CYC — Pisum sativum

Summary

PSAT1G061800 (CYC, also known as PsTCP1) on chromosome 1LG6 encodes a TCP transcription factor containing a CYC/TB1_R domain, with DNA binding and transcription coactivator activity. The gene is associated with regulation of shoot development, secondary shoot formation, seed dormancy, gibberellic acid homeostasis, and salicylic acid-mediated signaling. It is linked to specification of symmetry, determination of dorsoventral asymmetry, and sporocyte differentiation. Traits associated with CYC include plant male sterility, pollen fertility, seed set percent, shoot system elongation, whole plant size, flowering time, drought tolerance, and salt tolerance. Additional associations involve leaf morphology, trichome morphology, anther morphology, anthocyanin content, and root meristem development. The gene localizes to the nucleus. Studies of related genes in other species link the family to leaf elongation, brassinosteroid biosynthesis, plant growth, and heat stress memory.
