NAC2 — Capsicum annuum

Summary

CaNAC2 (T459_17011) on pepper chromosome 6 encodes a NAC domain-containing protein 45, a transcription factor with sequence-specific DNA binding and protein homodimerization activity. It is associated with diverse biological processes including floral organ senescence, chlorophyll breakdown, capsorubin anabolism, abscisic acid homeostasis, lateral root morphogenesis, and response to unfolded protein. The gene is linked to leaf senescence, stem senescence, anther morphology, adventitious rootless, auxin sensitivity, oxidative stress response, disease tolerance, and salt tolerance. It localizes to the nucleus, cytoplasm, and plasmalemma. Studies of related genes in other species connect this gene family to wound healing, fruit yield, combined salt and drought stress tolerance, age-related resistance, and Fusarium wilt resistance.
