HAG1 — Brassica napus

Summary

BnHAG1 (also known as BnMYB28, HAG1, PMG1) on chromosome A03 of oilseed rape encodes a protein with a Myb_TF_plants domain, capable of sequence-specific DNA binding and transcription factor activity. It is associated with the regulation of glucosinolate biosynthetic processes, including aliphatic and indolic glucosinolate metabolism, the shikimate pathway, and cellular responses to sulfur starvation. The gene has been linked to defense responses against insects and pathogens, including Sclerotinia sclerotiorum resistance, as well as to seed protein content, sulfur content, flowering time, root architecture, and stress tolerance traits such as drought and salt stress. It also shows connections to lignin biosynthesis, secondary cell wall biogenesis, and stomatal complex development, with the protein localizing to the nucleus.
