CUC2 — Asparagus officinalis

Summary

A4U43_C04F15190, symbol CUC2 (also known as AoCUC2, ANAC098, and other synonyms), encodes a NAC domain-containing transcription factor on asparagus chromosome 4. The product possesses DNA binding and transcription coactivator activity. This gene is associated with the regulation of plant organ formation, meristem initiation, and organ boundary specification between lateral organs and the meristem. It is linked to secondary shoot formation, lateral root morphogenesis, xylem development, and reproductive structure development. Associations with traits include leaflet morphology, leaf margin serration, axillary bud morphology, shoot system elongation, seed set, whole plant size, gynoecium development, shoot growth angle, plant male sterility, and sensitivity to gibberellic acid and cytokinin. Studies of related genes in other species link the family to shoot apical meristem formation, floral development, and organ boundary development.
