C2 — Zea mays

Summary

ZmC2 (ZM00001EB358600) on maize chromosome 8 encodes a C2-domain protein with kinase regulator activity, protein phosphatase inhibitor activity, abscisic acid binding, phospholipid binding, and GAP activity. It is associated with ABA signaling, jasmonic acid signaling, defense response, response to wounding, salinity response, blue light response, geotropism, and regulation of fumonisin anabolism. The protein localizes to the tonoplast, plastid, mitochondria, plasmalemma, cytosol, and nucleus. ZmC2 is linked to traits including seed yield, plant height, vegetative growth time, root thickness, lateral root length, stomatal closure and resistance, transpiration rate, leaf senescence, anthocyanin content, disease tolerance, and responses to high and low temperature stress. Studies of related genes in other species connect the family to phototropism, disease resistance, salinity tolerance, heat tolerance, and seed dormancy.
