RAO2 — Arabidopsis thaliana

Summary

AT1G34190 (RAO2, also known as NAC017 or ANAC017) encodes a NAC domain-containing transcription factor with DNA binding, transcription cis-regulatory region binding, protein binding, and NAD ADP-ribosyltransferase activities. In Arabidopsis thaliana, this gene is associated with mitochondrial retrograde signaling, the mitochondrial unfolded protein response (mtUPR), energy homeostasis, and responses to oxidative stress, hydrogen peroxide, superoxide, and antimycin A. It is linked to growth, stress tolerance, anoxia tolerance, and growth retardation phenotypes. The protein localizes to the ER membrane, cytoplasm, and nucleus. Associations include traits such as yield, submergence tolerance, sulfur content, aluminum response, stem and leaf senescence, plant height, root development, stomatal resistance, jasmonic acid sensitivity, and disease tolerance. Studies of related genes in other species link the family to leaf relative water content, fruit length, lycopene and carotenoid content, water use efficiency, and seed dormancy.
