FBP — Beta vulgaris subsp. vulgaris

Summary

BvFBP (BVRB_1G011460) on sugar beet chromosome 1 encodes a fructose-1,6-bisphosphatase, a class-1 enzyme with fructose 1,6-bisphosphate 1-phosphatase activity and metal binding. This gene is associated with fructose 1,6-bisphosphate metabolism, gluconeogenesis, the pentose-phosphate shunt, and sucrose and starch metabolism. It is linked to nitrogen utilization, glutamate metabolism, amino acid transport, fermentation, and regulation of flavonoid anabolism. Localization evidence connects the product to the cytosol, cytoplasm, and nucleus. The gene has been associated with photosynthetic rate, seedling growth and development, root length and morphology, as well as starch and sucrose content, starch accumulation, and the starch-to-sucrose ratio. Studies of related genes in other species link the family to glucose and proline content, net photosynthetic rate, water use efficiency, and stomatal opening.
