NAC2 — Arabidopsis thaliana

Summary

AT5G39610, also known as NAC2, NAC6, ORE1, and ANAC092, encodes a NAC domain-containing protein that localises to the nucleus and is annotated with sequence-specific DNA binding, transcription cis-regulatory region binding, protein homodimerization activity, DNA binding transcription factor activity, and protein binding. In Arabidopsis, this gene is associated with floral organ senescence, ovule senescence, floral fertility, chlorophyll breakdown, auxin breakdown, starch breakdown, seed growth, response to nitric oxide, and regulation of chlorophyll biosynthetic process. It is linked to numerous traits including leaf senescence, stem senescence, fruit senescing quality, seed weight, seed maturation, root development, photosynthetic ability, chloroplast development, salt response, submergence tolerance, oxidative stress response, ethylene sensitivity, abscisic acid sensitivity, disease tolerance, and heterosis. Studies of related genes in other species link the family to age-related resistance, disease resistance, and wheat fusarium head blight response.
