CUC2 — Brassica napus

Summary

BnCUC2 (DARMORV10_C02P17800.1) on chromosome C02 of oilseed rape encodes a NAC-domain transcription factor with 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, secondary shoot formation, and pistil development. It is linked to leaf margin serration, leaflet morphology, seed set percent, seed yield, shoot axis branching, plant male sterility, pollen fertility, gibberellic acid sensitivity, cytokinin sensitivity, shoot growth angle, whole plant size, and abiotic stress response. The encoded protein localizes to the nucleus, endoplasmic reticulum, trans-Golgi network, and recycling endosome. Related genes in other species are linked to cotyledon separation, embryonic shoot meristem formation, and leaf margin dissection.
