INTRODUCTION
• The Asian Herbs in Space (AHiS)
programme activities provided by
Asian Beneficial Collaboration for
Kibo Utilization (Kibo-ABC) under
provision of Japan Aerospace
Exploration Agency (JAXA),
• Kibo is nick name for Japanese
Experiment Module (JE) for
the International Space Station (ISS)
developed by JAXA
• Collaboration provides scientist with
opportunities experiments under
space conditions including
microgravity.

INTRODUCTION (cont)
• Through AHiS, a batch of Malaysia herb
candidate, Basil (Ocimum Santcum) will be
grown for 25 – 30 days onboard of the ISS,
tentatively on May to September 2016
• Astronauts will assist to activate the
germination, monitor and observe the
germination in space and transmit the image
back to earth. The herbs growth during the
mission will be also collected and brought back
for scientific sample analysis

INTRODUCTION (cont)• Holy basil (Ocimum sanctum, 2n=16) ,
draft nuclear genome sequence of 386
Mb
• family-Lamiaceae
• cultivated throughout Southeast Asian
tropics
• contains high in vitamin A and C
• Pre-clinal study on animal showed
antidiabetic effect (Narendhirakkannan
et al, 2006), wound healing activity
(Udupa et al, 2006), antiinflammatory
(Kelm et al 2000) and anticancer
properties (Karthikeyan et al, 1999).

CONCLUSIONS
• Germination of control Holy basil is higher
compare to treatment with nutrient
• Germination time of Holy basil treated with
nutrient treatments is slower compare to
control
• Growth of seedling height, leaf size, leaf no
is higher in low seed density due to less
competition
• Fresh weight (biomass) is higher in high
seed density (T5) due to nutrient efficiency

CONCLUSIONS (cont)
• Necrotic leaves due to nutrient
imbalance and deficiency/toxicity
• Established RNA extraction method
from Holy basil
• Established extraction method for
metabolomic analysis
• Established method for macroscopic
and microscopic studies
