Recent developments in sequencing and genotyping technologies are changing the landscape of scientific opportu-nities for large genome cereal species such as wheat and barley. The existing sequence of rice, to-gether with the rapidly accumu-lating sequence information from the maize, sorghum and Brachy-podium genomes, are providing a valuable set of comparative cereal sequence and functional genomics resources that can be exploited in large genome species. Despite the inherent difficulties that come from work-ing with a large genome, barley (Hordeum vulgare), with with 5.3 billion letters of genetic code, has many advantages - an extensive collection of mutants (http://ace.untamo.net/) and a continuum of interfertile germplasm that spans the range from wild H. spontaneum (Figure1 ) material in the Fertile Crescent to landraces and advanced modern cultivated germplasm. It is also a simple diploid with 7 chromosome pairs, which are essentially equivalent to those in each of the 3 ge-nomes of hexaploid wheat.

One of the first major devel-

opments in barley genomics was the generation of a BAC library from the American cul-tivar, Morex. This was followed by the creation of significant EST sequence resource (cur-rently standing at >450,000; see http://harvest.ucr.edu) which led in turn to a series of sequence based genomics resourc-es, including the Barley1 Affymetrix GeneChip (one of the first major arrays for a crop plant [see http://www.plexdb.org/]) and a series of Barley TILLING populations (e.g.

http://germinate.scri.sari.ac.uk/barley/mutants/).

The International Barley Sequencing Consortium (IBSC) (http://barleygen-ome.org/), formed from a nucleus of leading barley

research groups, is now working to develop a physical map

based on BAC on High Infor-mation Content Fingerprint-ing and BAC end sequencing from a recently extended series of Morex BAC libraries.

A recent major advance in barley genetics has come from the development of a high

throughput SNP platform for barley based on the Illumina Golden Gate Assay (Proc Natl Acad Sci USA (Figure 2) 103:18656–18661). This high throughput SNP platform will provide barley research-ers around the world with a unique integrated mapping

and diversity analysis platform based on more than 3,000 gene sequence based markers and will lay the foundation for a series of major new projects such as the UK, SEERAD and BBSRC LINK funded, AGOUEB (http://www.agoueb.org) and the US, USDA

funded, Barley-CAP (http://www.barleyCAP.org) projects inte-grated through a common infor-matics infrastruc-ture (Figure 3 and http://germi-nate.org.uk/).

These de-velopments are bringing a new

dimension to barley breeding and genetics which will lay the foundation for our understand-ing of the barley genome and increase the value of barley as the temperate cereal crop of choice to exploit major scientific developments in “model” plants such as Arabidopsis and rice.

Check out these educational resources:WheatCap http://maswheat.ucdavis.edu/education/RiceCap http://www.ricecap.uark.edu/outreach.htmDolan DNA Learning Center http://www.dnalc.org/home.htmlAn exciting part of working at a University is to do out-

reach to local schools and to get kids excited about science. For the past 5 years the McCouch Rice Lab group from Cornell (http://ricelab.plbr.cornell.edu/) has worked with three upstate NY schools to bring equipment, re-sources and experi-enced researchers into the classroom to benefit their students taking the Living Environment course, usually students in 9th or 10th grade. Once again, early in May, Dr. Susan McCouch worked with students who participated in two laboratory exercises - DNA extraction and gel electrophoresis – that helped them to understand the biological concepts behind modern DNA testing procedures.

The teachers participate because students get the oppor-tunity to do college level activities while gaining insight into future roles that science plays in the world. Traditionally the concepts of genomic DNA are taught to high school students in abstract form – through discussion and reading. “This lab allows the students to apply it in real life, to understand the process, and to work with tools that are otherwise unavailable to them,“ one teacher reported. “It also allows them to interact with pro-fessionals in the field - to ask them about their experiences and get answers to questions they have about working in a lab.”

McCouch captivated students as she set the background for the lab work. She told of how rice and rice genomics are crucial to addressing the challenges facing the world today. Although agricultural grain production has more than tripled since 1945, the world popula-tion growth has outgrown grain production. And many of the world’s poorest people consume the less nutritional white rice because it uses less fuel for cooking and has better storage characteristics in hot moist climates. With over 250,000 germplasm acces-sions of rice available to researchers, the genomic diversity from these varieties can be used to breed rice cultivars adaptable to a wide range of environ-ments and with better nutritional quality and higher yield production. For example, in Africa flooded rice fields would harbor diseases such as malaria – which is the number -one killer of children under the age of five, so current work is on de-veloping better varieties for the production needs of Africa. Im-provements in rice can also direct improvements in other cereal

crops, all with larger genomes than rice. Teachers commented about feedback from the students on the presentation. “They are always amazed by her (McCouch’s) presentation, because they have not previously been forced to see food and water as a privilege.”

The students learned about techniques that molecular biologists and geneticists use in their labs everyday to try to solve some of the problems that the world is

facing. This challenge was accepted by grinning students, who froze and

crushed plant leaves in liquid nitrogen and used finely cali-brated pipettes to measure DNA into the agarose gel plates. Their interest was obvious as they asked questions about how genomics and biotechnology affect them. A student from one school stated, “That was cool, everything we did in lab I saw on CSI (a television drama) last week.” A ninth grader said “I’m go-ing to go home and tell my father about this, and he isn’t going to believe it!” Some students also had the option to grow a rice plant and to view a rice flower under a microscope.

One of the senior teachers said that guest presenters are important in order to keep the students’ interest. His comment, “There are so many job opportunities in science . . . When you tell kids about them they don’t ‘get it’, but when they see it they get excited,” proved true as many students remarked that grind-ing rice leaves and using pipettes was fun, and they were inter-ested in doing further laboratory work. Another teacher had his students participate in the event because “This class puts it all

together – taking the different con-cepts and units that we teach and putting them into one lab.”

McCouch and her laboratory staff - includ-ing graduate students - plan on continuing to offer this lab

experience to the local schools, and are looking forward to new students and new experiences next year.

Contact Gramene through the “Feedback” link at the top of any page to ask ques-tions. Here are some recent questions that have been answered.

Q: Using my data in the pathways module, a certain pathways are painted in red (upregulated). Further, the details analysis revealed that some of the genes of the pathway are down regulated . Please explain this contradiction.

A: When there are multiple genes involved in a single step, the soft-ware makes a decision whether to display a pathway as being up or down regulated based upon a weighted average of all the known data. Any choice made will be misleading in some set of circumstanc-es. As Omics viewer chooses the color based on the value that has the greatest deviation from zero, the discrepancy in your results can be explained by the fact that the seven-fold upregulation of one of the genes overwhelms the four-fold downregulation of the other three

genes.

Q: I’m trying to find a whitepaper that was referenced in the 2006 highlights of the NPGI, http://www.nsf.gov/bio/pubs/reports/npgi2006/highlights.htm, regarding bioinformatics. A: The paper can be found at http://www.gramene.org/resources/plant_databases.pdf It is linked from our site map at http://www.gramene.

org/sitemap.html

Q. How do I get the full set of rice genome annotations - for the entire genome? The BioMart interface seems to limit me to doing a single chromosome at a time.

A. If you do not enable the chromosome filter, then you should be able to download all genes.

Unlike other cereals that are used for animal feed, the majority of rice is used for human consumption (83% of the 628,198,180 tonnes produced in 2005), for an average of 122 grams (4.3 ounces) per capita per day. Rice is the staple source of calories for the world’s poorest people, many of who consume 340-930 grams per day (.75-2 pounds per day) (FAOSTAT, 11 May 2007, http://faostat.fao.org/).
