TCP1 — Cucumis melo

Summary

MELO3C007121.2, designated CmTCP1, encodes a protein containing a CYC/TB1_R domain and a TCP domain. The product is annotated with DNA-binding transcription activator activity, protein dimerization activity, pinoresinol reductase activity, and phosphorelay response regulator activity. In melon, CmTCP1 is associated with specification of symmetry, proximal/distal pattern formation, adaxial/abaxial axis specification, regulation of plant organ morphogenesis, and positive regulation of photomorphogenesis and anthocyanin metabolism. The gene is linked to numerous traits including leaf flexibility, leaf area, sepal and petal morphology, anther morphology, plant male sterility, seed set percent, seed viability, shoot axis branching, vegetative vigor, whole plant size, brassinosteroid content, gibberellic acid sensitivity, photoperiod-sensitive flowering time, and responses to temperature stress, aphids, and submergence. Studies of related genes in other species connect the family to fruit shelf life, tuberization, male sterility, and disease resistance.
