CUC2 — Asparagus officinalis

Summary

A4U43_C09F3920, symbol CUC2 (also known as AoCUC2, ANAC098, and other synonyms) on asparagus chromosome 9, encodes a NAC-domain transcription factor with DNA-binding and transcription coactivator activity. This gene is associated with the regulation of plant organ formation, meristem initiation, organ boundary specification between lateral organs and the meristem, secondary shoot formation, lateral root morphogenesis, xylem development, and reproductive structure development. It has been linked to numerous traits including leaflet morphology, leaf margin serration, axillary bud morphology, seed set, shoot system elongation, whole plant size, gynoecium development, shoot growth angle, respiration rate, male sterility, gibberellic acid and cytokinin sensitivity, adventitious root formation, shoot axis branching, seed yield, pollen fertility, and vegetative growth time. Related genes in other species are linked to shoot apical meristem formation, cotyledon boundary specification, and floral organ separation.
