TCP1 — Cucumis melo

Summary

MELO3C023772.2, designated CmTCP1 on melon chromosome 7, encodes a transcription factor with a CYC/TB1_R domain and TCP family signature, possessing DNA-binding and transcription coactivator activity. In melon, CmTCP1 is associated with tendril development, specification of symmetry, determination of dorsoventral asymmetry, regulation of shoot development and secondary shoot formation, anther development, sporocyte differentiation, gibberellic acid homeostasis, salicylic acid-mediated signaling, hyperosmotic salinity response, phloem transport, and regulation of seed dormancy and germination. The gene is also linked to traits including plant male sterility, pollen fertility, seed set percent, shoot system elongation, whole plant size, leaf and floral organ morphology, anthocyanin content, flowering time, and vegetative growth. Studies of related genes in other species connect the family to plant height, drought tolerance, heat stress memory, and nitrogen metabolism.
