SOC1 — Brassica oleracea

Summary

BoSOC1 (BOLC102_C03P031860.1_BOLC102_V1) on cabbage chromosome 3 encodes a MADS-box transcription factor with a K-box domain, possessing RNA polymerase II transcription regulatory region sequence-specific DNA binding and transcription corepressor activities. This gene is associated with the regulation of flowering time, including both upregulation and downregulation of the vernalization response, as well as reproductive shoot system development, floral whorl morphogenesis, stamen and carpel identity specification, meristem maintenance and determinacy, and seed growth. It has been linked to numerous traits including photoperiod-sensitive flowering time, days to flowering, flower and inflorescence morphology, petal number, leaf color, stem elongation, anthocyanin content, and responses to high temperature, UV light, and drought. The gene product localizes to the nucleus, cytosol, and nucleolus. Studies of related genes in other species link the family to floral meristem determination, inflorescence architecture, seed yield, and stress responses including salt and osmotic stress resistance.
