NAC — Solanum tuberosum

Summary

PGSC0003DMG400032555, designated NAC (synonyms StNAC032, ANAC002, ATAF1, NAC102), encodes a NAC domain-containing transcription factor on potato chromosome 4. The protein exhibits DNA-binding transcription activator activity, sequence-specific DNA binding, transcription cis-regulatory region binding, protein homodimerization activity, and histidine kinase binding. It localizes to the nucleus and cytosol. This gene is associated with skin development, wound healing, regulation of root hair elongation, response to water, and asexual reproduction. Associations also include leaf necrosis, starch yield and content, chlorophyll content, anthocyanin content, net photosynthetic rate, water use efficiency, stomatal resistance, ethylene sensitivity, shoot fresh weight, root thickness, and disease tolerance. Studies of related genes in other species link the family to drought tolerance, ABA sensitivity, thermomemory, and resistance to Pseudomonas syringae, while tomato studies connect it to fruit ripening and bacterial pathogen resistance.
