HIG1 — Brassica oleracea

Summary

BoHIG1 (MYB51) on cabbage chromosome 8 encodes a protein with a Myb transcription factor domain, placing it in the plant Myb family. The gene is associated with a wide range of molecular functions, including xylogalacturonan beta-1,3-xylosyltransferase, spermine synthase, and methionine synthase activities, as well as biological processes such as xylogalacturonan metabolism, determination of dorsal identity, and acceptance of pollen. It has been linked to numerous agronomically relevant traits, including starch grain size, seed protein content, biomass yield, drought stress response, spikelet fertility, and resistance to powdery mildew and aphids. Additional associations include sulfur deficiency response, pollen tube reception, auxin signaling, thermotolerance, and cell wall biogenesis. Related genes in other species are linked to stress tolerance, salicylic acid accumulation, and fruit development.
