STRUCTURAL AND MOLECULAR BIOLOGY

Development of novel bio-molecules and the discovery of disease makers and drug target genes through structural biology,

biochemistry, and bioinformatics.

X-ray crystallography and molecular biology approaches to elucidate structural interactome including protein-protein interactions

and protein-ligand binding mechanisms.

Bioinformatics and systems biology approaches to discover protein localization, protein interaction and targeting mechanisms of

cell signaling molecules. Systemic and quantitative analysis of molecular evolution and biological network to study cancer drug

sensitivity and resistance mechanism to improve current drug developmental processes.

CELL AND DEVELOPMENTAL BIOLOGY

Establishment of a complex organism from a single cell followed by growth and ageing is a major component in the life events

and understanding of underlying mechanism touches the fundamentals of biology. In the field of cell and developmental biology,

we investigate the various biological phenomena at multiple levels from cell to organism using cutting-edge experimental

techniques encompassing molecular, biochemical, genetic, and neurobiological approaches. Based on the outcome, we attempt to

provide useful information to elucidate the pathophysiological mechanisms underlying the diseases caused by malfunction of the

normal biological processes and to ultimately contribute to the advance of therapeutic approaches.

We investigate complex and elaborate regulatory processes underlying the development of an organism from a

single cell including cellular differentiation, morphogenesis, and organogenesis, which will lead us to the

advanced therapeutics as well as to biological understanding various diseases.

We attempt to genetically analyze major players associated with ageing, thereby understand the biological

program controlling organismal ageing at the molecular level. From this, we pursue novel mechanistic insights

into the pathogenesis of various age-related disorders.

We investigate the role of the intracellular communication molecules, including soluble factor and nanosome, and

membrane proteins in the signal transduction among cells, which will lead us to the mechanisms underlying

tumor growth, metastasis, and immune response and to the useful information for the development of novel

diagnostics and therapeutics.

We investigate the information transmission process in neural circuits from the various angles to understand

higher brain functions, to grasp pathological mechanisms underlying various neuropsychiatric disorders at the

molecular level, and ultimately to establish the system to identify novel therapeutics.

MOLECULAR MEDICINE

New trends in life sciences are to improve the quality of life with conquering diseases based on basic science and interdisciplinary

research. The Molecular Medicine group of Department of Life Sciences, POSTECH leads various biological fields in the world from

identification of diseases, immunity, cell signaling, and gene transcription/translation mechanism at cellular and molecular levels

to development of diagnosis and therapeutics. Our group is focusing on development of novel regulatory molecules and

understanding of their function, development of vaccine and therapeutic agents for viral infection and inflammation by systematic

integration of gene transcription and translation, understanding of defense mechanism and its principle. And we eventually try to

apply these scientific achievement to clinical treatments for allergic disease, autoimmune disease, transplantation, and etc.

PLANT SCIENCES

The Plant Sciences Group is actively pursuing to understand fundamental biological processes involved in plant development and

growth from the stage of germination to that of senescence in model organisms. We also aim to translate the basic and

fundamental principles of plant systems into plant biotechnology for rebuilding crop traits and resolving environmental issues. The

major research topics are as follows.

Using Arabidopsis, we are investigating the mechanisms of how eukaryotic cells produce their cellular proteins, in particular

organellar proteins, and of how these cellular proteins are dynamically and spatially regulated at the molecular, biochemical,

cellular, genetic levels in order to elucidate the functions and operating principles of various organelles, and ultimately to

understand the operating principles of eukaryotic cells. In addition, we would like to develop cellular tools and methods to

reprogram plant cells to produce a large amount of valuable proteins and secondary metabolites.

With an aim to contribute to the production of Biofuel, we are also investigating basic mechanisms of lipid production in plants and

microalgae. We identified several genes that can increase lipid content of seed oil, and continue our search of genes that confer

heavy metal tolerance and oil accumulation in plant and microalgae. In addition, we are developing plants for phytoremediation,

which can clean up contaminated sites in an environmentally-friendly and economic manner.

As the form and function of plants is mainly determined by efficient communication among cells, tissues and organs, and cross-

talks with environmental stimuli, we aim to understand how plants integrate environmental cues into intrinsic developmental

programs such as phytohormone signaling networks. We are also investigating epigenetic regulations of the induced resistance

against various pathogens in genome level, prompting to understand symbiotic interactions between plants and bacteria, and

revealing how plants control cambial activities, vasculature development, and biomass production. To this end, we are taking

‘systems biology’ approaches with interdisciplinary researches, which provides a comprehensive research tool to understand these

complex interactions viewed as the keys to understanding life.

| Research Introduction |

For normal cell proliferation and division, maintenance of genomic

stability is essential. To protect the DNA from genotoxic stresses and

repair their damages, it is crucial to understand the molecular network

and functions of the proteins inside the cell (ex; tumor suppressors,

cell cycle regulators, and DNA damage signaling proteins). We have

provided molecular insight in understanding the mechanism of

maintaining genomic stability through the structural and functional

studies of these proteins. We elucidated the mechanism by which

eukaryotic replication licensing occurs once per cell cycle through the

studies of the Geminin-Cdt1 complex (Nature, 2004), and provided the

basis for inactivation mechanism of the E2F transcriptiona factor by

Retinoblastoma to halt the cell cycle progression for DNA repair (Genes

Dev 2002). We also provided the mechanism by which eIF4A, a

translation initiation factor, is regulated bya tumor suppressor PDCD4

(PNAS USA, 2009). We also determine the DNA recognition mechanism

by the 9-1-1 complex (Genes Dev, 2007) and the Mre11-Rad50

complex (Genes Dev, 2011) and repair the damaged DNA by the

Mus81-Eme1 complex (Genes Dev, 2008). Understanding the basis of

the genomemaintenance mechanism would allow us to prevent

and/or cure the accumulation of DNA damage, and in practice, reduce

the side effect of Radiation or Chemotherapy in treatment of cancer.

| Research Introduction |

Proteins play central roles in biological systems. They are not

functioning as a single entity, but are frequently multifunctional while

interacting with other biomolecules like proteins, l ipids or

carbohydrates after various post-translational modifications. We are

focusing on the roles of proteins which are key effector molecules of

the signaling networks from the point of systems biology. Since

various biological phenomena like cancer, aging, metabolism etc. are

closely related to each other at the molecular level, we are

investigating mechanistic actions of key effector molecules based on

the structure-function relationship and their interactions with other

molecules in various mechanistic processes such as autophagy,

apoptosis, metastasis, etc. in the signaling networks under specific

conditions like hypoxia, starvation, or inhibition of target molecules.

We also engineer protein and biofunctional nano molecules for

biomedical application.

| Research Introduction |

Research in my laboratory focuses on protein dynamics and signaling

through post-translational protein modifications. N-terminal

acetylation is one of the most common protein modifications. For

example, more than 80% of soluble human proteins are N-terminally

acetylated. However, over the past half century, the physiological roles

of N-terminal acetylation largely remained a mystery. In 2010, we

discovered that N-terminal acetylation of cellular proteins creates

specific degradation signals for ubiquitin-mediated proteolysis. While

we are interested in all aspect of protein modifications and signaling,

the work in my laboratory concentrates on the machinery and

functions of N-terminal acetylation-dependent proteolysis, cross-talks

between ubiquitin-mediated pathways, cotranslational protein

degradation, and protein quality control. We also have an interest in

the development of new drugs or targets that selectively inhibit the

activity of disease-specific components of N-terminal acetylation and

ubiquitin-mediated proteolysis.

| Research Introduction |

Protein-protein interactions (PPIs) and protein subcellular localizations

are crucial for many biological functions. Although advances in high-

throughput proteomics enable us to construct many comprehensive

PPI networks providing holistic view of biological phenomena, there

are huge amount of unidentified PPIs. Furthermore, little attention is

paid for the network-level understanding of diverse characteristics of

PPI. We attempt to solve these problems by integrating various

approaches such as modeling physical property of PPI, subcellular

localization information, and high-throughput genomics data. We also

focused on evolution of protein structures and sequences. While the

number of sequenced genomes continues to increase, experimentally

verified functional annotations and structures of whole genomes

remains unknown. Because subsequence experimental investigation is

costly and time-consuming, accurate computational methods for

predicting protein functions and structures become attractive. We

develop various computational methods for identifying functionally

important residues and modeling structures by using evolutionary

information.

| Research Introduction |

We aim to understand the role of myeloid cells (monocytes and

macrophages) in the progression of hypoxic (low oxygen tension)

inflammatory diseases including cancer and cardiovascular diseases. In

particular, we are interested in determining the function of hypoxia-

inducible factor-1 (HIF-1) in myeloid cells during the disease

progression. Myeloid cells play a critical role in initiation, progression,

and exacerbation of the diseases. Furthermore, hypoxic sensing by

these cells is known to be essential for mediating inflammatory

responses (such as in bacterial infection). However, it is currently

unknown how HIF-1, the major transcription factor stabilized under

hypoxic conditions, in myeloid cells may modulate the disease

progression, in which chronic accumulation of subtle changes in

hypoxia and inflammatory microenvironment may overall govern the

disease progression. Hence, by using the genetically manipulated

mouse model we seek to understand how myeloid cells under the

control of HIF-1 may modulate the disease process. With our research,

we hope to identify novel therapeutic targets to combat these

diseases more effectively in patients.

| Research Introduction |

HCV is a pathogenic virus causing hepatitis, liver cirrhosis, and

hepatocellular carcinoma. More than 170 million people are suffering

from this virus infection worldwide. We are investigating the

molecular basis of the pathogenic processes of HCV. We showed that a

human protein GRP94 is required for viral proliferation and that GRP94

is involved in persistent production of HCV in the presence of a

cytokine (TRAIL) triggering host cell death. Currently we are

developing a cure for HCV infection based on the inhibitors of NS5A

that is a viral protein essential for RNA replication.

Cap-independent translation of eukaryotic mRNAs requires a specific

RNA structure, named internal ribosomal entry site (IRES), and IRES-

specific cellular factors along with basic translational machinery. We

are investigating the molecular mechanism of translation via IRESs by

revealing the roles of cis-acting elements in various IRES [viral

(encephalomyocarditis virus, poliovirus and hepatitis C virus) and

cellular (BiP and c-myc) IRESs] and cellular factors (ITAFs) specifically

enhancing the IRES function.

We are trying to reveal the molecular details of translational regulation

of gene expression at various physiological conditions such as

inflammation, heat stress, and viral infection. We also study the

molecular mechanism of persistent translation of stress-resistant

mRNAs such as hepatitis c virus (HCV) mRNA at stress conditions when

translation of most mRNAs is repressed.

| Research Introduction |

The current research in the lab focuses on the study of innate immunity

and inflammation which provide the human body with the first line of

defense mechanisms against invading pathogens. While well-

orchestrated innate immune responses are essential for human health,

unregulated and overactivated immune responses may cause acute or

chronic inflammatory diseases as well as autoimmune diseases. The goal

of our research is to elucidate the cellular and molecular mechanisms of

the innate immune responses and to provide the framework for

therapeutic intervention of inflammatory and autoimmune diseases.

| Research Introduction |

Since the mammalian host has evolved to accommodate colonizationby symbiotic bacteria communities (the microbiota), host immunesystem must have adapted to maintain the homeostasis of themicrobiota while retaining the integrity of our body. In fact, there aresome connections between the microbiota and the development ofour immune system, particularly the gut-associated lymphoid tissues(GALT). Furthermore, some components of gut microbiota can becirculated systemically and modulate the activities of immune cells.Our Lab is primarily investigating the immune regulation achieved bythe interplay between host immune system and the microbiota inmultiple immune cells, including T cells, antigen-presenting cells(APC), and hematopoietic stem & progenitor cells (HSPC). We are alsostudying the role of tumornecrosis factor (TNF)/TNF receptor familymolecules in modulating the activities of immune cells. In particular,our Lab has an interest in exploring whether TNF/TNFR familymolecules can regulate the biology of HSPC in the chronic inflammation.

| Research Introduction |

We are currently investigating the roles of ATXN1 protein family and

CIC transcription repressor complexes in cancer progression and

metabolism using mice as a model organism. By generating tissue

specific either Cic or ATXN1 protein family knock-out mice, we are

investigating roles of CIC and ATXN1 protein family in cancer

progression and metabolism in particular tissues. We are also

interested in molecular functions of this transcription repressor

complex. We are trying to identify novel CIC target genes including

non-coding RNA genes and regulators for the activity of the ATXN1

protein family and CIC transcription repressor complexes. In summary,

a better understanding of functions of the ATXN1 protein family and

CIC transcription repressor complexes is a primary research goal in our

lab.

We are working on the machinery and principles of cell signaling from

receptor to cell growth and metabolism to understand the processes of

diseases such as cancer and diabetes. Signaling proteomics, ligand

discovery, aptamer development and disease mouse models are the

major strategy for the research in the lab. Molecular imaging, network

modeling and discovery of drug and diagnostics are also included in

the interdisciplinary collaborative projects. EGF Receptor and Insulin

Receptor signalings are major targets in current projects.

Phospholipase D, C1-Ten and mTOR are core signaling hub we have

been working on. Tens of modulators including peptides, chemicals

and aptamers are now in the process of development as candidates

for drugs. Members of Signal Transduction Lab have been contributed

| Research Introduction |

Since 1989, Prof. Sung has conducted extensive research in the field of

vaccine and immunotherapy. His specialty has been developing

therapeutic DNA vaccines for treating incurable diseases, including

chronic hepatitis B, CIN/VIN, and tuberculosis, and he managed to

expand his vaccine research from mouse model to non-primate, and

ultimately to human patients (from bench to clinic). Many of these

vaccines are currently being evaluated in clinical trials in collaboration

with various pharmaceutical and biotech companies. Recently, he has

been focusing on mesenchymal stem cell (MSC)-based gene therapies

and antibody-fusion proteins. Based on the positive results obtained

from preclinical studies, he plans to apply genetically engineered MSCs

for cancer therapy and utilize hyFc-fusion technology for treating

various types of infectious diseases as well as non-infectious diseases

in clinic. Through many years of experiences in academia and industry,

he has been establishing a global collaboration network among

universities, institutions, hospitals, and companies to build a

foundation for improving biotechnology in Korea and pioneering next

generation therapeutics to save the lives of patients.

| Research Introduction |In multicellular organisms, including humans and bacteria, intercellular

communication is an essential process. Cells release a variety of

intercellular communication molecules into their surroundings that

execute intracellular and intercellular communication via binding to

their cognate receptors.

To communicate with each other, cells secrete not only variable kinds

of soluble intercellular communication molecules, such as growth

factors and cytokines, but also extracellular vesicles (EVs), composed

of various kinds of proteins, lipids, and genetic materials. EVs are

extracellular organelles that modulate immune response as well as

promote tumor invasion. These observations suggest that EVs could be

regulators of intercellular communication, playing diverse roles

compared with those of soluble intercellular communication

molecules. However, the biological functions of EVs are generally

unclear. We discovered that EVs from tumor cells promote

angiogenesis via sphingomyelin and modulate VEGF action on

endothelial cells. We will demonstrate that EVs act as multifunctional

intercellular communicators through systemic research on the diversity

and multiple roles of EVs as well as on the mechanisms of EV

biogenesis. Furthermore, our researches will help us to develop novel

cancer diagnostics and to identify novel targets that are involved in

pathogenesis of diseases.

Aged humans experience higher rated of cancer, Alzheimer’s disease

and atherosclerosis. The pathogenesis of these diseases is not known

at the molecular level. Because disregulation in the biogenesis of

intercellular communication molecules and/or dysfunction in the

intercellular/intracellular communication networks could lead to

progression of several diseases, many groups have studied this field.

However, worldwide studies have only focused on soluble intercellular

communication molecules and intracellular communication. Therefore,

the systemic studies on EVs are critical for understanding the

intercellular communication network that is essential for decoding the

secrets of life and elucidating the exact causes of many diseases.

| Research Introduction |

Our lab focuses on the understanding of various signaling pathways

during vertebrate development. Specifically, we are trying to elucidate

molecular mechanisms of signaling pathways important for early

embryogenesis, including pattern formation and germ layer

differentiation using Xenopus model system.

Wnt, FGF, BMP and TGF- ‚ pathways are key signaling govern various

developmental process and serious human diseases. Wnt signaling

serves as core signal for proper body axis formation and

morphogenesis and related with cancer. FGF and BMP signaling is

important for brain development and TGF- ‚ pathway is crucial for

germ layer formation and tumor progression. Our aim is to reveal the

details of those pathways in the molecular level by vertebrate model

and cell-line based approach.

| Research Introduction |

We are interested in elucidating how neurons are interconnected and

affect each other, and how synapses are modified at the cellular and

molecular level. Synapses, the points of contact and communication

between neurons, can vary in their size, strength, and the number.

These differences contribute to learning and memory, beyond the

plasticity of neural networks and synapses.

First, we study synaptic plasticity and alteration by means of changes

in the level of gene expression using viral vectors and transgenic

animals. Using genetically modified materials, we can reveal

mechanism of spike time dependent plasticity (STDP), dopamine’s role

in synaptic plasticity or involvement of cell adhesion molecules such as

Neuroligin-1. Whole-cell recording is a critical method for observing

neural activity in living neurons, and we also use this technique to

observe changes of synaptic plasticity. Moreover we apply behavior

experiment using rodents, to find the physiological meaning of

alteration in synaptic plasticity caused by genetic modification.

Second, early symptoms of neurodegenerative diseases appear

apparent with failures in synaptic functions. So we pursue the

pathophysiology of neurodegenerative diseases such as Alzheimer’s

disease (AD). Toward this end, we employ variety methodologies,

inducing LTP in vivo or acute slice, time-lapse imaging of synaptic

structures, and optical determination of bimolecular interaction as well

as standard biochemical assays.

We collect evidences about the regulating machinery of Abeta

oligomer by naturally-secreted extracellular vesicles and find out their

effects on AD model using in vivo electrophysiology or AFM methods

Third, chronic exposure to drugs of abuse (e.g. cocaine) makes long-

lasting addictive memory. We investigate electro-physiological,

structural and behavioral changes to study long-term changes of

reward circuit. Because dopamine D1 and D2 receptor show opposite

direction of response in the nucleus accumbens, and they are

separately expressed in specific cell type, we are eager to distinguish

the functional properties of each type of neurons. BAC transgenic mice

(Drd1a-EGFP, Drd2-EGFP) enable us to study drug addiction in a cell-

type specific manner.

Finally, we also conduct systemic approach to study neuronal circuits

for functional understanding of various brain areas. For this, we

employ a cutting-edge method, optogenetics, which enables us to

control the activity of distinct type or group of neurons by optical

stimuli. Thus, we can accurately see the role of only optically

stimulated neural population in vivo or in vitro. Currently we are

applying this technique on drug addiction and fear memory research.

Molecular Neurophysiology (MNP) is currently interested in molecular

and cellular signaling mechanism in neuronal system. We are

particularly focusing on novel protein kinase network, dendritic

mRNAs, biological clock genes, cell cycle and cell apoptosis. We are

currently studying functional roles of vaccinia related kinases (VRKs)

family involved in cell cycle progression and neurodegenerative

diseases mediated by protein aggregation. The molecular mechanisms

of mRNA oscillation controlled by regulated transcription and mRNA

decay are also main topics in my laboratory. In addition, transport,

translational control and decay process of mRNAs in the dendritic

spines of neuronal cells are also investigated to reveal the mechanism

of dynamic synaptogenesis and synaptic plasticity. For more

comprehensive research, we are conducting interdiciplinary research

with other expertise including X-ray microscopy, computational

modeling and drug delivery system. We are elucidating the images of

brain and other organs which have defects during development. In

addition, cell death process induced by VRK inhibitors is being

investigated to possibly apply the technology to treat tumors or

neurodegenerative diseases.

Members of MNP have been successfully developing scientific careers

in molecular neurophysiology field since 1991.

| Research Introduction |

Aging is a fundamental mystery in biology. Although a number of

genetic and environmental factors that affect aging have been

discovered, the mechanisms by which these factors influence aging

are poorly understood. This is mainly due to the difficulty in studying

complex aging processes at the organismal level. The roundworm C.

elegans is an excellent model animal to overcome these complications

because of its genetic tractability, ease of culture in controlled

environments and very short lifespan. In our laboratory we plan to

elucidate the molecular mechanisms by which these genetic and

environmental factors regulate lifespan using C.elegans as a main

model organism. Since many findings on the regulation of aging in

C.elegans have already been shown to be amazingly well conserved

during evolution, we believe our research may eventually help us

understand the secrets of human aging and improve the quality of old

age.

Mental illness such as mood disorders, schizophrenia and drug

addiction is one of the most prevalent diseases in modern human

society. However, the molecular mechanisms underlying pathogenesis

of those diseases are largely unknown. Recently, the Molecular

Psychiatry - molecular neurobiological study of psychiatric disorders -

has emerged as a promising research domain of the modern

neuroscience, rendering a unique approach to understanding the

pathogenesis of various psychiatric disorders. To this end, we pursue in

depth understanding of the molecular basis of major psychiatric

disorders, utilizing contemporary biochemical, molecular biological, cell

biological, pharmacological, genetic and behavioral biological

techniques. We believe that the research will not only unravel novel

molecular targets for therapies for major psychiatric disorders but also

expand our knowledge on higher brain functions.

Modulation of dopamine receptor-mediated signaling

Dopamine is one of the most functionally prevalent neurotransmitters

in the vertebrate brain. Its role in higher brain functions is mediated by

five subtypes of dopamine receptors. Among them, dopamine D2

receptor (D2DR) has been implicated in major psychiatric diseases

including mood disorders, schizophrenia and drug addiction. We are

attempting to identify modulatory components in D2DR-mediated

signaling in the context of higher brain functions and the pathogenesis

of associated disorders.

Molecular modeling of schizophrenia

Schizophrenia is a complex psychiatric disorder that is thought to have

both neurochemical and neurodevelopmental causes in its

pathogenesis. The complexity of the pathogenesis has been interfering

establishment of the genuine molecular model. Recent advances in

human genetics provided reliable candidategenes causative in the

expression of schizophrenia. We attempt to understand their

physiological function to elucidate the molecular basis of

schizophrenia.

| Research Introduction |

The form and function of plants is mainly determined by efficient

communication among cells, tissues and organs, and cross-talks with

environmental stimuli. In higher plants, regulation and coordination of

growth and morphogenesis utilizes phytohormone signals for efficient

distribution of carbon source. We are interested in elucidating signaling

networks of various phytohormones such as cytokinin, auxin,

brassinosteroid, abscisic acid, and salicylic acid. We have constructed

our own °Æinteractome°Ø database and molecular networks as a

platform to explore the cross-talks among different phytohormones

and environmental conditions. We are also investigating epigenetic

regulations of the induced resistance (e.g. priming) against various

pathogen attacks in genome level. In addition, we are prompting to

understand how legume plants develop the nodules for nitrogen

fixation. Recently, we have extended our research areas to address

fundamental questions on how plants control cambial activities,

vasculature development, and biomass production. To this end, we are

taking ‘systems biology’ approaches with interdisciplinary researches,

which provides a comprehensive research tool to elucidate these

complex interactions viewed as the keys to understanding life.

| Research Introduction |

The plant cell is composed of various subcellular compartments. To

coordinate and regulate all these subcellular compartments to function

as a single unit, a large number of molecules must be involved in

these complex processes. Therefore, we are trying to isolate and

characterize important molecular players of these processes by

molecular, biochemical, and cellular approaches. We have discovered

and characterized many important proteins in various steps of

intracellular trafficking pathways and elucidated the molecular

mechanisms of protein trafficking. Endocytosis is another important

area of our research. Now, we are trying to understand how abiotic

and biotic stress responses are regulated by protein trafficking and

endocytosis. In addition, we are also actively studying molecular

mechanisms of protein targeting to chloroplasts and mitochondria. We

started to elucidate the cytosolic events involved in protein targeting

to chloroplasts and mitochondria. Furthermore, by deciphering the

protein targeting mechanisms to these endosymbiotic organelles, we

are trying to understand the evolution of these organelles. Another

important research topic is to develop molecular and cellular tools to

develop the plant cells as a protein production system for valuable

proteins.

| Research Introduction |

We have three major goals. First is to identify genes for bioenergy

production. Second is to develop trees for phytoremediation, a

technique to clean up environment using plants. Our third goal is to

understand functions and regulations of ABC transporters of plant.

To achieve these goals, we 1) investigate which genes increase oil

accumulation and biomass increase in plants and algae, 2) identify

which genes can contribute to plants’ resistance to heavy metals,

environmental pollutants, and other stresses, and 3) identify the

substrates and physiological roles of the many ABC transporters of

plants. For the candidate genes, we investigate their action

mechanisms, using many state of the art technologies. Then we

generate transgenic poplar trees and algae by expressing the

candidate genes, and finally, test whether these transgenic plants

effectively remediate the pollutants, or produce bio-energy materials,

in green house and in the field.

| Research Introduction |

Plants and microbial pathogens co-evolve their mechanisms of

detection and evasion, respectively. Pathogen effectors attenuate

plant immunity by interfering with the function of their host target

proteins. In turn, plants evolved disease resistance (R) proteins, often

carry NB-LRR domains that are also found in mammalian immune

receptors, that can recognize corresponding effectors and activate a

strong defence system known as effector-triggered immunity. Our

research focus is to identify effectors from economically important

pathogens and their corresponding R genes in order to investigate

their functions in detail. In addition, we aim to use these resources to

develop future crop breeding strategies for enhanced disease

resistance and biomass production.
