SOC1 — Brassica oleracea var. botrytis

Summary

BoSOC1, located on chromosome 3 of cauliflower (Brassica oleracea var. botrytis), encodes a MADS-box transcription factor that binds RNA polymerase II regulatory regions and acts as a transcription corepressor. This gene is associated with the regulation of flowering time, vernalization response, floral organ identity specification, meristem maintenance, and seed growth. It has been connected to numerous traits including days to flowering, photoperiod-sensitive flowering time, flower and inflorescence morphology, leaf number, petal number, and responses to high temperature, UV light, and cytokinin. Associations also extend to carotenoid anabolism, plastid and chloroplast development, anthocyanin content, and jasmonic acid levels. Related genes in other species are linked to drought escape, stress-induced flowering, cold tolerance, disease resistance, and vegetative phase transition.
