HIG1 — Brassica oleracea var. botrytis

Summary

BoHIG1, also known as MYB51, is a cauliflower gene on chromosome 8 that encodes a protein containing a Myb DNA-binding domain, placing it in the plant Myb transcription factor family. The gene is associated with a wide array of molecular functions, including xylogalacturonan beta-1,3-xylosyltransferase, spermine synthase, and 12-oxophytodienoate reductase activities, as well as biological processes such as xylogalacturonan metabolism, determination of dorsal identity, root meristem specification, and acceptance of pollen. BoHIG1 has been linked to numerous agronomically relevant traits, including biomass yield, seed protein content, drought stress response, inflorescence branch arrangement, spikelet fertility, and responses to aphids, powdery mildew, aluminum, and phosphorus. It is also connected to phenotypes such as sulfur deficiency response, auxin signaling, thermotolerance, and cell wall biogenesis. Related genes in other species are linked to stress tolerance, immune response, and plant growth and development.
