Abstract
To date nothing is known about how specificity to either cold or to drought is encoded in plants. To date only components which are common to both have been identified. This proposal is for research aimed at identifying signalling components which are specific either for cold or for drought responses of plants. In Arabidopsis the cold-induced gene, DREB1A, and the drought-induced gene, DREB2A, will be used as specific markers for cold and drought signalling respectively. Promoter analysis of these two genes will allow the identification of DNA elements which mediate cold and drought-specific expression. The hypothesis that AtHK1, the Arabidopsis osmosensor and ABA are involved in the drought-specific (DREB2A) pathway will also be tested. Finally, promoter elements in the DREB2A promoter which are responsive to ABA will be identified.
