UniProt Comments
Involved in disease resistance response (PubMed:16115070, PubMed:19625399). May function as repressor of pathogenesis-related proteins (PubMed:16115070). May function in the regulation of host basal defense responses against viral infection (PubMed:19625399). Transcriptional activator involved in responses to wounding and infection with tobamovirus (TMV) (PubMed:22937923). Binds to the DNA sequences 5'-AAAATATCT-3' and 5'AGATTTTT-3' of CYP734A1/BAS1 and CYP72C1/SOB7 promoters, respectively. Acts as suppressor of the brassinosteroid (BR)-inactivating enzymes CYP734A1/BAS1 and CYP72C1/SOB7, and prevents their expression in almost all tissues. Plays a central role in integrating BR homeostasis and seedling development. Regulates the spatial regulation of BR homeostasis and participates in the regulation of hypocotyl elongation and root growth by suppressing BR catabolism. Mediates connection between BR catabolism and photomorphogenesis (PubMed:26493403). Binds to, and transactivates the promoter of the auxin biosynthetic gene NIT2 (PubMed:22965747). Stress-responsive NAC transcription factor involved in ABA-inducible leaf senescence signaling (PubMed:26518251). Required for normal seed development and morphology (PubMed:18849494).
