Grower Benefits:
•Improved
stress tolerance allows earlier planting and further reduces yield
variability and grower financial risk
•70-80
million acres in US suffer yield losses due to moderate water stress.
•The
most critical time for water stress is near pollination and flowering.
e.g. yields with or without irrigation can vary 100%. Dry land acres
(Kansas) can yield less than 100 bu/a without irrigation and 200 bu/acre
with irrigation.
•About
15% of US corn acres are irrigated. A lot more acres would grow corn if
yields were higher due to drought tolerance. About 20 million acres in
US would benefit from a drought tolerance gene that gives a 10% yield
increase. An additional 5 million acres could move from some other crop
to corn if we had drought tolerance. On these new acres we would
capture 100% of new units sold and associated trait fees etc.

Science:
•Gene
C source is transcription factor from arabidopsis. Found in arabidopsis
screens. In the process of moving this gene into crops.
•Gene
D is a different gene from microbial sources which confers broad stress
tolerance to cold, heat and drought. What we show here is drought
tolerance.
•Water
availability and temperature stress are major causes of yield loss
•We
use our Genomics platform to screen for genes which reduce yield loss
under these conditions
•The
bottom right pictures show target genes in Rice plants under common
stress conditions
