DELT1 — Arabidopsis thaliana

Summary

AT5G47910 (DELT1, also known as RBOHD) in Arabidopsis thaliana encodes a respiratory burst oxidase homologue D, a NADPH oxidase family protein with NAD(P)H oxidase H2O2-forming activity, calcium ion binding, and multiple kinase activities. This gene is associated with reactive oxygen species anabolism, superoxide release, detection of insects, membrane depolarization, and responses to paraquat. It has been connected to numerous traits including bacterial blight disease resistance, submergence tolerance, grain yield, biomass yield, leaf rolling, hydrogen peroxide content, aluminum response, aphid response, UV-B light sensitivity, and phototropism. The gene is linked to phenotypes such as drought tolerance, cold tolerance, nematode resistance, cadmium tolerance, salinity-alkalinity stress tolerance, root hair development, and pollen development. Studies in related genes in other species connect the RBOH family to heat stress tolerance, salt tolerance, and pathogen defense responses.
