NAC4 — Zea mays

Summary

ZM00001EB264380, designated NAC4 and ZmOMTN5, encodes a NAC-domain protein on maize chromosome 6. The protein possesses sequence-specific DNA binding and homodimerization activities. This gene is associated with diverse developmental and regulatory processes including leaf morphogenesis, endosperm development, reproductive structure development, organogenesis, histogenesis, photoperiodism, auxin transport, abscission, the MAPK cascade, sucrose metabolism, and CoA biosynthesis. It has been linked to agronomically important traits such as grain yield, grain size, plant height, leaf width and shape, root length, lateral root length, germination rate, cell membrane stability, and drought tolerance. Additional associations include responses to hormones and metals, induced systemic resistance, and phenotypes related to plant architecture, male sterility, and dwarfism. The protein localizes to the endoplasmic reticulum.
