DEP — Brachypodium distachyon

Summary

BRADI_1G08340V3 (DEP/VRN1) on chromosome 1 of Brachypodium distachyon encodes a MADS-box transcription factor containing a MADS-box and K-box domain. The protein localises to the nucleus, cytosol and nucleolus, binds DNA and dimerises, and is annotated with both transcription factor and corepressor activity. This gene is associated with the regulation of the vegetative-to-reproductive phase transition, vernalization response, inflorescence and floral meristem identity, fruit and seed development, and organogenesis. It is linked to photoperiod-sensitive flowering time, heading date, grain weight, panicle and inflorescence morphology, root and crown root development, drought tolerance, abiotic stress response, leaf senescence, anthocyanin content, photosynthetic rate, and responses to UV light, high temperature, cytokinin and brassinosteroids. Studies of related genes in other species link the family to flower senescence and abscission, grain shape, tillering and internode elongation.
