TGA2 — Arabidopsis thaliana

Summary

AT5G06950 (TGA2) encodes a TGACG sequence-specific DNA-binding protein that belongs to the bZIP transcription factor superfamily and possesses salicylic acid binding, calmodulin binding, and transcriptional co-regulator activities. In Arabidopsis thaliana, TGA2 is associated with UV-B-induced oxidative stress tolerance, auxin and salicylic acid responses, and transcriptional regulation. The gene has been linked to diverse biological processes including systemic acquired resistance, nectary development, stamen morphogenesis, petal formation, and response to photooxidative stress. TGA2 localizes to the nucleus, cytoplasm, and mitochondria, and participates in NPR1/NH1-mediated hormone signaling pathways. Associations with agronomically relevant traits include bacterial blight disease resistance, drought sensitivity, seed set percent, plant male sterility, and responses to various fungal pathogens including rice sheath blight and wheat stripe rust.
