VRN2 — Brassica oleracea

Summary

BoVRN2 (BOLC102_C08P016860.1) on cabbage chromosome 8 encodes a protein with a Znf_SUZ12 domain and VEFS-Box, and is annotated with histone H3K27 trimethylase activity, chromatin binding, and DNA binding transcription factor activity. It is associated with photoperiodism, flowering time, vernalization response, and the vegetative-to-reproductive phase transition, as well as cellular response to cold, seed and endosperm development, trichome differentiation, and shoot morphogenesis. The gene is linked to traits including days to flowering, leaf water potential, sulfur and oleic acid content, anthocyanin levels, auxin content, ethylene and abscisic acid sensitivity, and aphid response. It localizes to PcG and chromatin silencing complexes, euchromatin, heterochromatin, and the polar nucleus. Studies of related genes in other species connect the family to H3K27me3 histone modification, shoot apical meristem development, drought stress response, and fungal resistance.
