VI1 — Beta vulgaris subsp. vulgaris
Summary
BvVI1 (BVRB_5G097930) on sugar beet chromosome 5 encodes a protein with beta-fructofuranosidase and 6G-fructosyltransferase activities, belonging to the glycosyl hydrolase 32 family. The protein localises to the vacuolar membrane and lumen, and is associated with phloem unloading, sucrose metabolism, fructan biosynthesis, primary root development, cell division, and responses to abscisic acid, salt, and bacteria. It has been linked to sucrose content, seed weight, respiration rate, photosynthetic rate, and CO2 assimilation. Studies of related genes in other species connect the family to pollen germination and cell wall modification, and to drought tolerance, hexose accumulation, and low temperature tolerance.
