GRF3 — Brassica oleracea

Summary

BoGRF3 (GRF3) on chromosome 4 of cabbage (Brassica oleracea) encodes a GRF-family transcription coactivator that contains the characteristic QLQ and WRC domains and localises to the nucleus. It is associated with the regulation of gene expression, cell division, cell population proliferation, and organ growth, including leaf, root, seed, and gynoecium development. The gene has been linked to responses to gibberellin, cold, deep water, and nematodes, as well as to traits such as seed weight, water use efficiency, anthocyanin content, leaf morphology, and drought and stress tolerance. Studies of related genes in other species connect the family to leaf cell proliferation, organ size, seed size, and cold tolerance.
