SUS2 — Cucumis melo

Summary

MELO3C016129.2, designated CmSUS2 on melon chromosome 8, encodes a protein with alpha-1,3-mannosyltransferase and transglycosidase activities, placing it in the ALG2 family of glycosyltransferases. The gene is associated with oligosaccharide-PP-dolichol assembly and localises to the endomembrane system. CmSUS2 is associated with fruit sweetness, fruit weight, fruit size, stem length, stem diameter, and heterosis. Studies of related genes in other species connect the family to sucrose content, sugar content, and root mass density.
