SDC — Beta vulgaris subsp. vulgaris

Summary

BvSDC (BVRB_1G011320) on sugar beet chromosome 1 encodes a pyridoxal phosphate-dependent decarboxylase with histidine decarboxylase and serine decarboxylase activities. The enzyme is associated with ethanolamine, L-serine, and carboxylic acid metabolism, as well as choline biosynthesis, phenylpropanoid anabolism, and sucrose metabolism. It has been linked to cellular response to nitrogen starvation, salt stress, signal transduction, and cellular homeostasis. The protein localizes to the cytosol and plasma membrane. BvSDC is associated with leaf relative water content and with phenotypes including smaller size, sterility, multiple inflorescences, and early flowering under short days, as well as ethanolamine biosynthesis, phospholipid metabolism, and embryogenesis. Related genes in other species link the family to amino acid and phospholipid metabolism.
