FBP — Beta vulgaris subsp. vulgaris

Summary

BvFBP (BVRB_5G111310) on sugar beet chromosome 5 encodes a fructose-1,6-bisphosphatase, a class-I enzyme with fructose 1,6-bisphosphate 1-phosphatase activity and protein kinase activity. It is associated with the Calvin cycle, gluconeogenesis, the reductive pentose-phosphate cycle, and sucrose and flavonoid metabolism. The gene product localises to the chloroplast stroma, cytosol, apoplast and plasmalemma. BvFBP is linked to photosynthetic rate, root thickness, manganese sensitivity, osmotic response sensitivity, abscisic acid sensitivity, and disease tolerance. Phenotypic associations include soluble sugar content, starch accumulation, cyclic electron flow, root vascular layer number, stomatal development, and plant growth. Related genes in other species are linked to abscisic acid signaling, root growth, and traits including total soluble sugar content, sucrose content, starch content, root development, stomatal opening, oxidative stress response, plant growth and development, and photochemical quenching.
