A PP2C homolog gene was cloned from the drought-treated cDNA library of  Populus euphratica . Multiple sequence alignment analysis suggested that the gene is a potential ortholog of HAB1. The expression of this  HAB1  ortholog ( PeHAB1 ) was markedly induced by drought and moderately induced by ABA. To characterize its function in ABA signaling, we generated transgenic  Arabidopsis thaliana  plants overexpressing this gene. Transgenic lines exhibited reduced responses to exogenous ABA and reduced tolerance to drought compared to wide-type lines. Yeast two-hybrid analyses indicated that PeHAB1 could interact with the ABA receptor PYL4 in an ABA-independent manner. Taken together; these results indicated that PeHAB1 is a new negative regulator of ABA responses in poplar.
