One example of the fruit from these technologies is the identification and application of DREBgenes, which code transcription factors that induce the expression of stress-responsive genes. Over-expression of the DREB genes increases the tolerance of transgenic Arabidopsis plants to drought, high salinity and cold. Although these genes were initially identified in Arabidopsis, their presence and function in stress tolerance are well conserved in many other important crops. Using the DREBgenes, we are currently developing stress-tolerant soybean and rice.
In this project, we continue to develop technological infrastructure to facilitate identifying genes and promoters in stress responses, transferring them into important crops, and evaluating transgenic crops through field studies in collaboration with other institutes abroad, in order to produce stress-tolerant crops that can feed the hunger in developing countries.
