NAC5 — Oryza sativa Japonica

Summary

OS11G0184900 (NAC5) on rice chromosome 11 encodes a NAC-domain protein with DNA-binding transcription factor activity and transcription activator activity. In rice, NAC5 is associated with grain filling, grain size, panicle development, seed traits, and yield, as well as salt tolerance, oxidative stress response, lignin content, root hair elongation, leaf senescence, jasmonic acid response, and abscisic acid biosynthesis. The protein localizes to the nucleus and cytoplasm and is linked to carbohydrate, amino acid, and lipid transport, stomatal closure, anther development, and photomorphogenesis regulation. Studies of related genes in other species connect the family to drought tolerance, ABA sensitivity, thermomemory, and pathogen resistance, and to grain protein content.
