RHD2 — Cucumis sativus

Summary

CsRHD2 (CSA_3G845500) encodes a protein containing NADPH oxidase, FAD-binding, and EF-hand calcium-binding domains, with NAD(P)H oxidase H2O2-forming activity, calcium ion binding, and multiple kinase activities annotated. In cucumber, this gene is associated with immune response-regulating signaling pathways, defense response by callose deposition, respiratory burst involved in defense response, H2O2 biosynthetic process, root epidermal cell differentiation, and hormone metabolism. It is linked to numerous traits including grain yield, seed yield, biomass yield, bacterial blight disease resistance, aphid response, water use efficiency, leaf rolling response, root hair length, aluminum response, phosphorus uptake, and brassinosteroid sensitivity. Phenotypic associations include root hair elongation and development, lateral root induction, auxin distribution, cold tolerance, and cadmium tolerance. Related genes in other species are linked to salt stress tolerance, heat tolerance, oxidative stress tolerance, and lateral root development.
