VIN3 — Brassica oleracea var. botrytis

Summary

BoVIN3, encoded by BOLND125_CTG001510P000020.1_BOLND125_V1 on chromosome CBFFJS010000009.1 in cauliflower (Brassica oleracea var. botrytis), is a transcription factor with DNA binding, transcription corepressor binding, protein phosphorylated amino acid binding, and general protein binding activities. It contains VIN3-like, VIN3-like_C, and Oberon-like_PHD domains. The gene is associated with epigenetic regulation of gene expression, including epigenetic programming in the endosperm and downregulation of gene expression, as well as responses to cold, short-day flowering, hypoxia, and brassinosteroid-mediated signalling. It is linked to inflorescence development and regulation of flower development. BoVIN3 localises to the nucleus, cytoplasm, cytosol, chromatin silencing complex, nuclear speck, plant-type vacuole, Golgi complex, and mitochondria. Associations include flowering time, vernalization response, hypoxia tolerance, nitrate uptake, root morphology, seedling growth, leaf composition, and organ identity traits. Related genes in other species link the family to flowering and organ size.
