AGLU — Cucumis melo

Summary

MELO3C021782.2 (symbol CmAGLU) on melon chromosome 13 encodes a protein with alpha-glucosidase activity, specifically Glc2Man9GlcNAc2 oligosaccharide glucosidase activity, and belongs to the glycosyl hydrolase 31 family. The gene is associated with N-glycan processing, polysaccharide breakdown, and carbohydrate metabolism. It is linked to defence responses against bacteria and fungi, including bacterial blight disease resistance, and to responses to chitin, cold, and thirst. Localisation evidence connects the product to the vacuole, apoplast, endoplasmic reticulum, and plasma membrane. The gene is also associated with stomatal complex closure time, salt tolerance, and disease tolerance. Studies of related genes in other species link the family to chitin-induced immune signalling, innate immunity, and resistance to bacterial and fungal pathogens.
