A novel NAC transcription factor cooperates with bZIP-type transcription factors in dehydration and osmotic stress responses

ABSTRACT: Multiple transcription factors (TFs) play essential roles in plants under abiotic stress, one of the most challenging conditions of plant survival. However, how these multiple TFs cooperate in abiotic stress responses still remains largely unknown. In this study, we provide evidence that a novel NAC (NAM, ATAF1/2, and CUC2) transcription factor (ANAC096) cooperates with bZIP-type TFs [ABRE-binding factor/ABRE-binding protein (ABF/AREB)] in ensuring survival under dehydration and osmotic stress conditions. Intriguingly, ANAC096 directly interacted with ABF2 and ABF4, but not with ABF3, both in vitro and in vivo. ANAC096 and ABF2 synergistically activated RD29A transcription. The genome-wide gene expression analysis revealed that a major proportion of ABA-responsive genes are under the trans
