CYC — Pisum sativum

Summary

PSAT6G206120 (CYC, PsTCP1) on garden pea chromosome 6LG2 encodes a TCP transcription factor with a CYC/TB1_R domain, possessing DNA-binding and transcription coactivator activity. The gene is associated with the regulation of shoot development, secondary shoot formation, and gibberellic acid homeostasis, including both upregulation and downregulation of gibberellic acid-mediated signaling. It has been connected to seed dormancy, nitrogen utilization, salicylic acid-mediated signaling, and stress responses. Traits linked to this gene include plant size, stem elongation, leaf morphology, flowering time, seed set, pollen fertility, anther morphology, drought tolerance, and salt tolerance. The gene is also associated with dorsoventral asymmetry determination, sporocyte differentiation, meiotic cytokinesis, and phloem transport. Related genes in other species are linked to leaf elongation, brassinosteroid content, and plant growth.
