BRC1 — Arabidopsis thaliana

Summary

AT3G18550, also known as BRC1 or TCP18, encodes a TCP transcription factor with DNA-binding and transcription cis-regulatory region binding activities, and contains a CYC/TB1_R domain. In Arabidopsis thaliana, BRC1 is associated with axillary bud development, shoot branching, bud dormancy, and outgrowth, as well as responses to strigolactone, shade avoidance, and thermomorphogenesis. The gene is linked to numerous agronomic traits including harvest index, biomass yield, seed yield, leaf area, inflorescence height, fruit number, drought sensitivity, and photoperiod-sensitive flowering time. BRC1 localizes to the nucleus, cytoplasm, and membrane, and is associated with hormone metabolism, auxin transport, and sucrose anabolism. Studies of related genes in other species link the family to fruit ripening and leaf development.
