DAO — Cucumis sativus

Summary

CSA_6G491680, designated DAO, encodes a FAD-dependent oxidoreductase with D-aspartate oxidase and D-amino-acid oxidase activities, placing it in the FAD/NAD-binding superfamily. In cucumber (Cucumis sativus) on chromosome 6, this gene is associated with nitrogen utilization, redox activity, hydrogen peroxide-mediated signaling, auxin signaling, and organogenesis. It is linked to root development, including adventitious root formation, as well as cell division, signal transduction, and biofilm formation. The gene is also associated with S-nitrosylation and stomatal opening. Its product localizes to the cytoplasm and chloroplast. Studies of related genes in other species link the DAO family to leaf chlorosis, protein content, and salt tolerance, though these associations are not yet established in cucumber.
