VI1 — Cucumis melo

Summary

MELO3C005560.2 (symbol VI1, also known as CmVI1) on melon chromosome 10 encodes a protein with beta-fructofuranosidase and 6G-fructosyltransferase activities, belonging to the glycosyl hydrolase 32 family. The gene is associated with fruit development and ripening, sucrose and carbohydrate metabolism, and cellular responses to gibberellin and abscisic acid. It is linked to vacuolar localisation, cell wall biogenesis, primary root development, and responses to bacteria, salinity, and thirst. Associations with fruit shape, sugar content, respiration rate, photosynthetic rate, CO2 assimilation, photosystem II quantum yield, and lateral root development have been noted. Studies of related genes in other species connect the family to fruit sweetness, hexose and sucrose content, fruit fresh weight, drought tolerance, and pollen germination.
