SOC1 — Brassica napus

Summary

BnSOC1 (DARMORV10_C03P30160.1) on chromosome C03 of oilseed rape encodes a MADS-box transcription factor with RNA polymerase II-specific DNA-binding and transcription corepressor activities. This gene is associated with floral whorl structural organization, floral whorl morphogenesis, stamen formation, specification of stamen identity, seed growth, specification of carpel identity, maintenance of inflorescence meristem identity, maintenance of floral meristem identity, integument development, regulation of developmental process, meristem determinacy, regulation of meristem development, specification of floral organ identity, downregulation of photomorphogenesis, carpel development, specification of floral organ number, and reproductive structure development. It is associated with flowering time, photoperiod-sensitive flowering, seed growth, and integument development. Associations also include responses to high temperature, UV light, drought, and nutrient stress, as well as traits such as petal number, stamen morphology, anthocyanin content, and chloroplast development. Studies of related genes in other species link the family to floral meristem determination, inflorescence architecture, seed yield, and responses to cold, salt, and osmotic stress.
