RHD2 — Cucumis sativus

Summary

CsRHD2 (CSA_4G050170) on cucumber chromosome 4 encodes a FAD-binding FR-type domain-containing protein with NAD(P)H oxidase H2O2-forming activity, calcium ion binding, and multiple kinase activities. It is associated with respiratory burst in defense response, immune response-regulating signaling, callose deposition, H2O2 biosynthesis, root epidermal cell differentiation, and carbohydrate homeostasis. The gene is linked to numerous agronomically important traits including grain yield, seed yield, biomass yield, bacterial blight disease resistance, aphid response, water use efficiency, transpiration rate, root hair length and elongation, lateral root induction, root growth, phosphorus uptake, cadmium tolerance, cold tolerance, and salinity-alkalinity stress tolerance. Studies of related genes in other species connect the family to salt stress tolerance, heat tolerance, cold stress tolerance, late blight resistance, and reactive oxygen species homeostasis.
