CUC2 — Asparagus officinalis

Summary

A4U43_C01F31360, symbol CUC2 (also known as AoCUC2, ANAC098, and other synonyms), encodes a NAC domain-containing transcription factor on asparagus chromosome 1. The product possesses DNA binding, transcription cis-regulatory region binding, transcription coactivator activity, protein homodimerization activity, and protein binding functions. It is associated with the regulation of plant organ formation timing, organ boundary specification between lateral organs and the meristem, meristem initiation, secondary shoot formation, lateral root morphogenesis, xylem development, pistil development, and regulation of endosperm development. The gene is linked to numerous traits including leaflet morphology, leaf margin serration, axillary bud morphology, shoot system elongation, seed set, 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, and pollen fertility. Related genes in other species are linked to shoot apical meristem formation, organ boundary development, and floral organ separation.
