IPP — Beta vulgaris subsp. vulgaris

Summary

BvIPP (BVRB_6G129080) on sugar beet chromosome 6 encodes a pyrophosphatase with inorganic diphosphatase activity, magnesium binding, and DNA-binding transcription factor activity. It is associated with pyrophosphate and phosphate metabolism, lipid storage, cell wall thickening and biogenesis, pectin metabolism, regulation of starch biosynthesis, sucrose metabolism, indole glucosinolate anabolism, induced systemic resistance, defense response via callose deposition, and responses to insects and bacteria. The gene is linked to insect damage response, disease tolerance, root hair development, cell wall integrity, seed storage protein and oil content, glucosinolate and camalexin accumulation, immunity, and insect resistance. It localizes to the nucleus, cytosol, cytoplasm, and mitochondria. Studies of related genes in other species link the family to indolic glucosinolate biosynthesis, callose deposition, and resistance to bacterial pathogens.
