Transcription activator that binds to the ABA-responsive elements (ABREs) in vitro. Involved in abiotic stress responses and abscisic acid (ABA) signaling (PubMed:20039193). Involved in the signaling pathway that induces growth inhibition in response to D-allose (PubMed:23397192). Induced by anoxia, drought, salt stress, oxidative stress, cold and abscisic acid (ABA) (PubMed:20039193). Induced by D-allose (PubMed:23397192). No visible phenotype under normal growth conditions, but mutant plants exhibit increased sensitivity to salt and drought stresses. Plants overexpressing BZIP12 exhibit increased sensitivity to D-allose-induced growth inhibition. Truncated N-terminus. Truncated N-terminus.
