VIN3 — Brassica oleracea var. botrytis

Summary

BoVIN3, encoded by gene BOLND125_C02P017750.1_BOLND125_V1 on chromosome 2 of cauliflower (Brassica oleracea var. botrytis), is a member of the VIN3-like protein family, containing VIN3-like_C and Oberon-like_PHD domains. The gene product has DNA-binding transcription factor activity and is associated with transcription corepressor and protein phosphorylated amino acid binding. BoVIN3 is linked to epigenetic regulation of gene expression, including epigenetic programming in the endosperm and downregulation of gene expression. It is associated with responses to cold, short-day flowering, hypoxia, and brassinosteroid-mediated signalling, as well as inflorescence development and regulation of flower development. The protein localises to the nucleus, chromatin silencing complex, nuclear speck, cytosol, cytoplasm, plant-type vacuole, Golgi complex, and mitochondria. BoVIN3 is associated with flowering time, vernalization response, drought tolerance, seed germination, root morphology, leaf composition, seedling growth, nitrate uptake, and organ identity traits.
