TGA1 — Brassica juncea

Summary

BJUA09G63330S, designated BjTGA1 on chromosome A09 of Indian mustard (Brassica juncea), encodes a bZIP transcription factor containing a TGA domain. The protein binds salicylic acid, DNA, and transcription cis-regulatory regions, and acts as a transcriptional co-regulator. BjTGA1 is associated with the regulation of systemic acquired resistance, salicylic acid- and jasmonic acid-mediated signaling, defence responses to bacteria and fungi, response to wounding, heat, hypoxia, and insects, as well as hypersensitive response programmed cell death. It localises to the nucleus, cytoplasm, and nuclear body. The gene has been connected to numerous traits including Cercospora leaf spot response, wheat stripe rust disease response, bacterial blight disease resistance, and wheat powdery mildew disease response, as well as drought sensitivity, nitrogen sensitivity, sulfur sensitivity, root development trait, leaf senescence trait, and inflorescence morphology trait.
