CUC2 — Phaseolus vulgaris

Summary

PvCUC2 (PHAVU_005G074500) on chromosome 5 of French bean encodes a NAC-domain transcription factor with sequence-specific DNA binding and transcription coactivator activity. This gene is associated with the regulation of plant organ formation, meristem initiation, and organ boundary specification between lateral organs and the meristem. It has been linked to abscisic acid homeostasis, xylem development, endosperm development, and secondary shoot formation. Associations with agronomic traits include leaflet morphology, leaf margin serration, leaf length, seed set percent, seed yield, shoot axis branching, plant male sterility, pollen fertility, vegetative growth time, stem elongation, and plant stress response. The gene is also connected to shoot regeneration, organ separation, leaf serration, and cotyledon boundary formation. Related genes in other species link the family to embryonic shoot meristem formation, cotyledon separation, and leaf margin dissection.
