AO — Triticum turgidum subsp. durum

Summary

TRITD2AV1G132310 (AO, TtAO) on durum wheat chromosome 2A encodes an aldehyde oxidase. The gene is associated with abscisic acid and auxin biosynthesis, carotenoid breakdown, glucosinolate metabolism, and cellular response to aldehyde and hydrogen peroxide. It is linked to photosynthetic rate, carotenoid content, and traits including seed germination, dormancy, stomatal movement, leaf senescence, salt and temperature stress responses, pathogen resistance, and root elongation. The protein localises to plastid, cytosol, and nucleus. Studies of related genes in other species connect the family to ABA biosynthesis, drought tolerance, and stomatal closure.
