The dehydration-responsive element binding protein (DREB) family is important in regulating plant responses to abiotic stresses. DREB2C is one of the Arabidopsis class 2 DREBs and is induced by heat stress (HS). Here, we present data concerning the interaction of DREB2C with heat shock factor A3 (HsfA3) in the HS signal transduction cascade. RT-PCR showed that HsfA3 is the most up-regulated gene among the 21 Arabidopsis Hsfs in transgenic plants over-expressing DREB2C. DREB2C and HsfA3… CONTINUE READING
