HIG1 — Brassica oleracea

Summary

BoHIG1 (BOLC102_C08P028190.1) on cabbage chromosome 8 encodes a protein with a Myb_TF_plants domain, placing it in the MYB transcription factor 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, pollen acceptance, root meristem specification, and determination of dorsal identity. It is linked to numerous agronomically relevant traits including starch grain size, seed protein content, biomass yield, drought stress response, spikelet fertility, inflorescence branch arrangement, lignin biosynthesis, oleic acid content, aphid response, aluminum response, and photoperiod-sensitive flowering time. The gene is also connected to phenotypes such as sulfur deficiency response, pollen tube reception, auxin signaling, thermotolerance, and cell wall biogenesis.
