RHD2 — Cucumis melo

Summary

MELO3C016333.2, also known as CmRHD2, encodes a respiratory burst oxidase homolog (RBOH) on melon chromosome 8. The product contains NADPH oxidase, FAD-binding, and EF-hand calcium-binding domains and is annotated with NAD(P)H oxidase H2O2-forming activity, calcium ion binding, and multiple kinase activities. This gene is associated with immune response-regulating signaling, 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, root growth, lateral root induction, auxin distribution, and root oxidative activity. Associations also include grain yield, seed yield, biomass yield, bacterial blight disease resistance, aphid response, water use efficiency, leaf rolling response, phototropism, and responses to aluminum, osmotic stress, and brassinosteroids. The gene is linked to pathways of superoxide generation, ROS homeostasis, root gravitropism, and responses to abiotic stimuli.
