HIG1 — Arabidopsis thaliana

Summary

AT1G18570, also known as HIG1 or MYB51, encodes a protein containing a Myb-like DNA-binding domain characteristic of plant transcription factors. In Arabidopsis thaliana, this gene is associated with resistance to bacterial pathogens and callose deposition. It is linked to the regulation of secondary metabolism, particularly indole glucosinolate metabolism, as well as responses to sulfur starvation. The gene is associated with numerous traits including starch grain size, biomass yield, seed protein content, submergence tolerance, and inflorescence architecture. Additional associations include lignin biosynthesis, aphid response, aluminum response, and photoperiod-sensitive flowering time. The encoded protein has been annotated with a wide range of molecular functions including gamma-glutamylaminecyclotransferase, GMP kinase, and spermine synthase activities.
