Abstract
WRKY transcription factors are a large protein family found in plants. The name of WRKY proteins is derived from their prominent DNA-binding region, designated the WRKY domain, a highly conserved region constituted by about 60 amino acid residues. It has been known that - WRKY transcription factors play important roles in the regulation of genes associated with plant defense responses - but the role of WRKY proteins in abiotic stress responses is still unclear in Arabidopsis thaliana. In this study, we showed that WRKY17, the member of WRKY IId subfamily, could interact with the HD2-type HDAC HD2C. Disruption of WRKY17 rendered plants sensitive to salt. Compared with wrky17.2 and hd2c-1 plants, wrky17.2/hd2c-1 double mutant plants displayed increased salt sensitivity. In addition, the expression of ABA-responsive genes was changed in these mutants. These data suggested that WRKY17 may play a role in abiotic stress responses.
