CUC2 — Brassica oleracea

Summary

BoCUC2 (BOLC102_C09P046560.1) on cabbage chromosome 9 encodes a NAC-domain transcription factor with DNA-binding and transcription coactivator activity. This gene is associated with the formation of plant organ boundaries, meristem initiation, secondary shoot formation, and the regulation of organ formation timing. It has been linked to chlorophyll breakdown, xylem development, autophagy, and negative regulation of gene expression. Traits connected to BoCUC2 include leaflet and leaf margin morphology, leaf length, seed set, shoot system elongation, whole plant size, shoot growth angle, gynoecium development, male sterility, seed yield, pollen fertility, shoot axis branching, stem elongation, and responses to gibberellic acid and cytokinin. The gene is also associated with shoot apical meristem formation, organ boundary size, leaf serration, and organ separation. Related genes in other species link the family to cotyledon separation, embryonic shoot meristem formation, leaf margin dissection, and chlorophyll degradation.
