SOC1 — Brassica juncea

Summary

BJUA03G36630S (SOC1, also known as AGL20) on Indian mustard chromosome A03 encodes a MADS-box transcription factor with RNA polymerase II-specific DNA-binding and transcription corepressor activity. This gene is associated with the regulation of vernalization response, floral meristem identity and maintenance, floral organ specification, stamen and carpel formation, integument development, and seed growth. It has been linked to numerous traits including flowering time, photoperiod-sensitive flowering, inflorescence and floral organ morphology, petal and sepal number and morphology, seed growth and development, chloroplast and plastid development, anthocyanin and jasmonic acid content, and responses to UV light, high temperature, drought, and other abiotic stresses. Studies of related genes in other species link the family to floral meristem determination, inflorescence architecture, seed yield, and responses to photoperiod and temperature.
