VIN3 — Brassica oleracea

Summary

BoVIN3, encoded by the cabbage gene BOLC102_C02P017620.1_BOLC102_V1 on chromosome 2, is a DNA-binding transcription factor with transcription corepressor and protein phosphorylated amino acid binding activities, belonging to the VIN3-like and Oberon-like PHD domain families. This gene is associated with epigenetic regulation of gene expression, including epigenetic programming in the endosperm and downregulation of gene expression. It is linked to flowering time, vernalization response, and regulation of flower, inflorescence, and anther development, as well as responses to cold, short-day conditions, and hypoxia. Additional associations include leaf senescence, carbohydrate metabolism, brassinosteroid-mediated signalling, meiosis, and shoot morphogenesis. The encoded protein localizes to the nucleus, chromatin silencing complex, cytosol, and other cellular compartments. BoVIN3 is also associated with traits such as flowering time, cytoplasmic male sterility, floral organ identity, nitrate uptake, and root morphology. Related genes in other species link the family to flowering and organ size.
