CUC2 — Brassica oleracea

Summary

BoCUC2 (BOLC102_C02P021370.1) on cabbage chromosome 2 encodes a NAC-domain transcription factor with DNA-binding and transcription coactivator activity. The gene is associated with the formation of plant organ boundaries, meristem initiation, and secondary shoot formation, as well as the regulation of organ formation timing and chlorophyll breakdown. It has been linked to numerous agronomically relevant traits including leaflet and leaf margin morphology, leaf length, seed set, shoot branching, stem elongation, plant size, flower and gynoecium development, male sterility, pollen fertility, and responses to gibberellic acid and cytokinin. Additional associations include xylem development, nitrogen utilization regulation, and autophagy. Studies of related genes in other species connect the family to cotyledon separation, embryonic shoot meristem formation, leaf margin dissection, and chlorophyll degradation.
