AGLU1 — Brassica oleracea

Summary

BoAGLU1, encoded by BOLC102_C03P006650.1 on cabbage chromosome 3, is a member of the glycoside hydrolase family 31, possessing alpha-glucosidase and oligosaccharide glucosidase activity. The gene is associated with N-glycan processing, polysaccharide breakdown, and carbohydrate metabolism. It is linked to defence responses against bacteria and fungi, including chitin signalling and detection of fungal and bacterial molecules, as well as positive regulation of the hypersensitive response. Localisation evidence connects the product to the vacuole, apoplast, endoplasmic reticulum, and plasma membrane. BoAGLU1 is also associated with agronomically relevant traits such as starch digestibility, bacterial blight disease resistance, anthocyanin content, stomatal closure, salt tolerance, and disease tolerance. Related genes in other species link the gene family to chitin-induced immunity, fungal resistance, and MAMP-triggered immunity.
