BADH — Beta vulgaris subsp. vulgaris

Summary

BvBADH (BVRB_1G023190) on sugar beet chromosome Bvchr1_un.sca019 encodes an aldehyde dehydrogenase domain-containing protein with betaine-aldehyde dehydrogenase (NAD+) activity, also annotated for 4-trimethylammoniobutyraldehyde, gamma-guanidinobutyraldehyde, 3-aminopropanal, and aminobutyraldehyde dehydrogenase activities, as well as Na+ and K+ ion binding and protein homodimerization activity. The gene is associated with glycine betaine and betaine anabolism, cellular response to anoxia, aldehyde detoxification, and responses to salt, salinity, thirst, and abscisic acid. It localizes to the plant-type cell wall, mitochondria, and cytosol. BvBADH is linked to flavonoid content, photosynthetic rate, and chlorophyll content, and is associated with drought tolerance and salt stress tolerance. Related genes in other species are linked to salt tolerance, glycine betaine synthesis, and seed development.
