RHD2 — Cucumis sativus

Summary

CsRHD2 (CSA_5G529950) on cucumber chromosome 5 encodes a protein with NADPH oxidase, FAD-binding, ferric reductase, and EF-hand calcium-binding domains, and is annotated with NAD(P)H oxidase H2O2-forming activity, calcium ion binding, and multiple kinase activities. The gene is associated with immune response-regulating signaling, respiratory burst in defense, callose deposition, H2O2 biosynthesis, root epidermal cell differentiation, and carbohydrate homeostasis. It is linked to leaf rolling response, sucrose synthase activity, magnesium sensitivity, grain yield, leaf elongation rate, plant dry weight, shoot system elongation rate, bacterial blight disease resistance, lignin biosynthesis, aluminum response, phototropism, phosphorus uptake, aphid response, biomass yield, leaf number, biotic plant stress, root oxidative activity, inflorescence morphology, seed yield, osmotic response sensitivity, leaf growth and development, root hair length, plant tissue development, transpiration rate, brassinosteroid sensitivity, water use efficiency, ethylene sensitivity, plant stress response, root meristem development, and stomatal complex closure time. Related RBOH family members in other species are linked to salt, cold, heat, and oxidative stress tolerance, lateral root formation, and defense responses.
