REM1 — Brassica oleracea var. botrytis

Summary

BoREM1 (REM1) encodes a B3 DNA-binding domain protein belonging to the REM (REPRODUCTIVE MERISTEM) family, localised to the nucleus and capable of binding both DNA and protein. In cauliflower, this gene is associated with inflorescence meristem growth, inflorescence phyllotactic patterning, flower development, pollen development, megagametogenesis, and DNA-dependent transcription. It has been connected to meristem identity, phyllotaxis, flowering time, and both male and female gametophyte development. Related genes in other species link the family to reproductive meristem development and early flowering under long days, while broader sequence similarity connections also associate the family with phyllotaxy and flowering time traits.
