CUC2 — Glycine max

Summary

GmCUC2 (GLYMA_12G226500V4) encodes a NAC-domain transcription factor with DNA-binding, transcription coactivator, and protein homodimerization activities. This soybean gene on chromosome 12 is associated with the regulation of plant organ formation, meristem initiation, organ boundary specification between lateral organs and the meristem, and abscission. It has been linked to abscisic acid homeostasis, xylem development, endosperm development, and nitrogen utilization. Associations with agronomic traits include leaflet morphology, leaf margin serration, seed set percent, seed yield, shoot axis branching, plant male sterility, pollen fertility, vegetative growth time, and plant stress response. The gene localizes to the nucleus, endoplasmic reticulum, and endosomal compartments. Related genes in other species link the family to cotyledon separation, embryonic shoot meristem formation, leaf margin dissection, and male fertility.
