HIG1 — Brassica oleracea var. botrytis

Summary

BoHIG1, also known as MYB51, is a cauliflower gene on chromosome 8 that encodes a protein with a Myb DNA-binding domain, placing it in the plant Myb transcription factor family. It is associated with a wide range 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, and root meristem specification. The gene has been linked to numerous agronomic traits, including starch grain size, inflorescence branch arrangement, spikelet fertility, drought stress response, seed protein content, biomass yield, and photoperiod-sensitive flowering time. It is also connected to phenotypes such as sulfur deficiency response, pollen tube reception, auxin signaling, and thermotolerance. Related genes in other species link the family to pollen tube reception and immune response.
