OBF4 — Zea mays

Summary

ZmOBF4 (also known as TGA4, TGA1, and BZIP113) on maize chromosome 10 encodes a bZIP transcription factor with a TGA domain, annotated with DNA binding, transcription coactivator activity, calmodulin binding, salicylic acid binding, and disulfide oxidoreductase activity. It is associated with the regulation of systemic acquired resistance, salicylic acid- and jasmonic acid-mediated signaling, defence responses to bacteria, nitrogen utilization and nitrate starvation responses, gibberellic acid homeostasis, seed dormancy, stamen morphogenesis, meiotic cytokinesis, and cell wall modification. The gene has been connected to numerous agronomic traits including bacterial blight disease resistance, Cercospora leaf spot response, drought sensitivity, plant male sterility, seed set percent, shoot system elongation rate, whole plant size, and responses to aluminum, nitrogen, and sulfur.
