OMTN1 — Oryza sativa Japonica

Summary

OS02G0579000, also known as OMTN1 or OsNAC5, encodes a NAC-domain protein that localizes to the nucleus and endoplasmic reticulum. The protein possesses sequence-specific DNA binding and homodimerization activity, and is associated with the regulation of transcription. In rice, this gene is linked to cadmium sensitivity and accumulation, chilling tolerance, and responses to salinity and drought. It is associated with the regulation of endosperm development, reproductive structure development, lignin anabolism, and signaling pathways involving ethylene, gibberellic acid, auxin, and abscisic acid. Associations with grain yield, plant height, root length, lignin content, and low-temperature stress response have also been noted. Studies of related genes in other species further link the gene family to stress responses and developmental processes.
