RHD2 — Cucumis sativus

Summary

CSA_1G495280 (RHD2/RBOHB) on cucumber chromosome 1 encodes an uncharacterized protein containing NADPH_Ox, FAD-binding, and EF-hand calcium-binding domains, with superoxide-generating NAD(P)H oxidase activity and calcium ion binding. This gene is associated with immune response-regulating signaling pathway, defense response by callose deposition, respiratory burst involved in defense response, and H2O2 biosynthetic process. It is linked to root hair elongation, root hair development and tip growth, lateral root induction, root growth, and root epidermal cell differentiation. Associations also include grain yield, seed yield, biomass yield, bacterial blight disease resistance, aphid response, water use efficiency, leaf rolling response, phototropism, aluminum response, phosphorus uptake, osmotic sensitivity, brassinosteroid sensitivity, and ethylene sensitivity. Studies of related genes in other species link the family to salt, cold, heat, and oxidative stress tolerance, as well as lateral root formation and photosynthetic induction.
