BADH — Solanum tuberosum
Summary
StBADH (PGSC0003DMG400024582) on potato chromosome 3 encodes a protein with aldehyde dehydrogenase domains and betaine-aldehyde dehydrogenase (NAD⁺) activity, along with activity toward 4-trimethylammoniobutyraldehyde, gamma-guanidinobutyraldehyde, aminobutyraldehyde and 3-aminopropanal, and binds Na⁺ and K⁺ ions. The enzyme is associated with glycine betaine biosynthesis III, cellular detoxification of aldehydes, and responses to abscisic acid, salinity and thirst. It localises to the cytosol, mitochondria and plant-type cell wall. StBADH has been connected to drought tolerance, salt stress tolerance, and traits including starch yield, protein content, plant height, chlorophyll content, photosynthetic rate, transpiration rate, stomatal resistance, leaf water potential, water use efficiency and proline content. Studies of related genes in other species link the group to salt tolerance and glycine betaine synthesis.
