ALDH4 — Phaseolus vulgaris

Summary

PHAVU_009G126400, designated PvALDH4 (also known as ALDH3H1), encodes an aldehyde dehydrogenase family protein on chromosome 9 of French bean (Phaseolus vulgaris). The product possesses NAD+-dependent aldehyde dehydrogenase activity, including betaine-aldehyde, gamma-guanidinobutyraldehyde, and 4-trimethylammoniobutyraldehyde dehydrogenase activities, and binds sodium and potassium ions. PvALDH4 is associated with cellular detoxification of aldehydes, alkanal metabolism, and responses to desiccation, salinity, and abscisic acid. The protein localises to multiple cellular compartments including the cytosol, plastid, amyloplast, endoplasmic reticulum, Golgi complex, and plasmodesmata. The gene is associated with drought tolerance, salt stress response, and dehydration stress response. Studies of related genes in other species link the family to abiotic stress tolerance traits, seed dormancy, and root length.
