GLU4 — Cucumis melo

Summary

MELO3C022160.2, also known as GLU4, is a melon (Cucumis melo) gene on chromosome 10 that encodes a protein belonging to the glycosyl hydrolase family 9 with cellulase activity (EC 3.2.1.4). This product is associated with cellulose breakdown, cell wall organization, fruit ripening, and seed development, and is localized to the extracellular space. The gene has been linked to fruit width and fruit weight traits. Studies of related genes in other species link the family to endoglucanase activity and cell wall remodeling, though these specific functions are not yet established for GLU4 in melon.
