ANAC2 — Arabidopsis thaliana

Summary

AT1G01720 (symbol ANAC2, also known as ATAF1) encodes a NAC domain-containing transcription activator with DNA-binding and transcription factor activity. In Arabidopsis, this gene is associated with drought tolerance, salt stress sensitivity and tolerance, ABA sensitivity, copper toxicity tolerance, and penetration resistance. It has been linked to the regulation of leaf senescence, xylem development, root hair elongation, thermomorphogenesis, and responses to water. Associations also include brassinosteroid and chlorophyll breakdown, starch anabolism, glucosinolate metabolism, and cell cycle control. The protein localises to the nucleus and cytosol. Studies of related genes in other species link the family to drought stress tolerance, resistance to bacterial pathogens such as Pseudomonas syringae, and chilling stress tolerance.
