RHD2 — Cucumis melo

Summary

MELO3C022917.2 (CmRHD2) on melon chromosome 11 encodes a respiratory burst oxidase homolog (RBOH) with NAD(P)H oxidase H2O2-forming activity, calcium ion binding, and multiple kinase activities. It is associated with immune response-regulating signaling, defense response by callose deposition, respiratory burst involved in defense response, and H2O2 biosynthetic process. The gene is associated with root hair elongation, root hair development, root growth, lateral root induction, auxin distribution, and cell wall strength. Associations also include grain yield, seed yield, biomass yield, bacterial blight disease resistance, aphid response, leaf rolling response, water use efficiency, transpiration rate, phototropism, aluminum response, phosphorus uptake, and brassinosteroid 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.
