Comprehensive analysis of the NAC transcription factor gene family in Sophora tonkinensis Gagnep.

ABSTRACT:

Background

Sophora tonkinensis Gagnep. has long been utilized in the treatment of anti-inflammatory and pain-relieving, with its principal active compounds being alkaloids and flavonoids. NAC transcription factors, a large family of plant-specific regulators, play pivotal roles in growth, development, stress responses, and secondary metabolism. However, comprehensive genome-wide characterization of S. tonkinensis NAC gene family (StNAC) remains unexplored.

Results

This study identified 85 NAC proteins from the S. tonkinensis genome database. Phylogenetic analysis revealed that StNAC proteins were categorized into 15 subgroups based on their homology with Arabidopsis thaliana NAC proteins. Gene structure analysis demonstrated a variation in intron numbers ranging from 1 to 7,
