CUC2 — Brassica napus

Summary

BnCUC2 (DARMORV10_A02P10670.1) on chromosome A02 of oilseed rape encodes a NAC-domain transcription factor with sequence-specific DNA binding, transcription coactivator activity, and protein homodimerization activity. This gene is associated with shoot apical meristem development, organ boundary specification between lateral organs and the meristem, formation of plant organ boundaries, meristem initiation, secondary shoot formation, and organogenesis. It has been connected to leaflet morphology, leaf margin serration, leaf length, seed set percent, seed yield, shoot system elongation, whole plant size, shoot growth angle, plant male sterility, pollen fertility, gibberellic acid sensitivity, cytokinin sensitivity, vegetative growth time, and abiotic stress response traits. The encoded protein localizes to the nucleus, endoplasmic reticulum, trans-Golgi network, and recycling endosome. Related genes in other species link the family to cotyledon separation, embryonic shoot meristem formation, and leaf margin dissection.
