BADH — Beta vulgaris subsp. vulgaris
Summary
BvBADH (BVRB_5G116250) on sugar beet chromosome 5 encodes a betaine-aldehyde dehydrogenase (EC 1.2.1.8) with 4-trimethylammoniobutyraldehyde, gamma-guanidinobutyraldehyde, and aminobutyraldehyde dehydrogenase activities, and binds Na⁺ and K⁺ ions. The enzyme is associated with glycine betaine and betaine biosynthesis, cellular detoxification of aldehydes, and responses to salt, abscisic acid, and thirst. It localises to the cytosol, mitochondria, plant-type cell wall, and chloroplast. The gene is linked to flavonoid content, photosynthetic rate, and chlorophyll content, and has been connected to drought tolerance and salt stress tolerance. Studies of related genes in other species link the family to salt tolerance, glycine betaine synthesis, and seed development.
