CUC2 — Brassica napus

Summary

BnCUC2 (DARMORV10_C09P44000.1) on chromosome C09 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, and the formation of plant organ boundaries. It has been linked to numerous agronomically relevant traits including leaflet and leaf margin morphology, seed set percent, seed yield, shoot branching, stem elongation, plant size, male sterility, pollen fertility, and responses to gibberellic acid and cytokinin. Additional associations include xylem development, secondary growth, cell wall biogenesis, autophagy, nitrogen utilization regulation, and localization to the nucleus, endoplasmic reticulum, trans-Golgi network, and recycling endosome. Studies of related genes in other species link the family to embryonic shoot meristem formation, cotyledon separation, and leaf margin dissection.
