Genetically Engineered Flood-Tolerant Rice
Using genetic mapping techniques, scientists from the International Rice Research Institute and the University of California have identified a gene called Sub1A that enables rice to survive complete submergence by controlling its response to plant hormones ethylene and giberellic acid, which play a role in submergence tolerance.
... the researchers introduced the Sub1A gene into a rice variety that is especially suited for growing conditions in India. The resulting rice plants were not only tolerant of being submerged in water but also produced high yields and retained other beneficial crop qualities.

Not only are submergence-tolerant varieties useful for use in areas prone to flooding; the researchers also suggest that these genetically modified rice varieties may also result to reduced herbicide applications as flooding may be used as an alternate weed control method. The plants are currently being developed for commercial production in Laos, Bangladesh and India.
