NAC

Brief Introduction

• The NAC gene family members are plant-specific transcriptional factors (TFs) derived from the names of NAM (no apical meristem, Petunia), ATAF1–2, and CUC2 (cup-shaped cotyledon, Arabidopsis), with a conserved NAM domain in the N-terminus. The C-terminal domain of NAC proteins is highly variable which was reported to act as a transcriptional activator or repressor.

• The NAC transcription factors are one of the key regulatory gene families involved in plant growth and defense. They have been reported to participate in many biogical processes, for example, maintenance of the shoot apical meristem, cotyledon development, lateral root development, flower formation, hormone signaling response to pathogen infection, plant organ senescence, embryo development, formation of secondary walls, cell division, fiber development, seed development and shoot branching determination..
