RHD2 — Cucumis melo

Summary

MELO3C005719.2 (CmRHD2) on melon chromosome 10 encodes a respiratory burst oxidase homolog (RBOH) with NAD(P)H oxidase H2O2-forming activity, calcium ion binding, and multiple kinase activities, including transmembrane receptor protein tyrosine kinase and calcium-dependent protein serine/threonine kinase activity. The protein contains NADPH_Ox, FAD-binding, ferric reductase, and EF-hand domains. CmRHD2 is associated with immune response-regulating signaling pathways, defense response by callose deposition, respiratory burst involved in defense response, H2O2 biosynthetic process, and detection of bacteria. It is linked to root hair elongation and development, lateral root induction, root growth, auxin distribution, and cell wall strength. Associations also include grain yield, seed yield, biomass yield, bacterial blight disease resistance, aphid response, water use efficiency, transpiration rate, leaf rolling response, phototropism, and responses to aluminum, osmotic stress, and ethylene.
