GRF3 — Brassica oleracea

Summary

BoGRF3 (GRF3) on chromosome 4 of cabbage (Brassica oleracea) encodes a GRF protein containing QLQ and WRC domains and functions as a transcription coactivator with cis-regulatory region binding and ATP-binding activities, localising to the nucleus. The gene is associated with the regulation of gene expression, cell division, cell population proliferation, organ growth, leaf and root development, seed development, and responses to gibberellin, cold, deep water, and nematodes. It is linked to traits including seed weight, leaf morphology, floral organ development, anthocyanin content, water use efficiency, and root oxidative activity, as well as to phenotypes such as drought tolerance, disease resistance, leaf senescence, and plant growth and development. Related genes in other species are associated with leaf cell proliferation, organ size, seed size, and cold tolerance.
