Abstrakt: Stress-tolerant crops are expected to express genes not normally expressed in susceptible crops. We have used desiccation stress coupled with high light intensity to identify groundnut as a relatively tolerant crop. Stress-responsive genes (Gdi, Groundnut Desiccation Induced) were cloned by subtractive hybridisation. The sequence of Gdi-15 shows homology to flavonol 3-O-glucosyltransferases, which are involved in anthocyanin biosynthesis. Gdi-15 transcripts increase markedly in response to stress, suggestive of a role in stress tolerance.
