RHD2 — Phaseolus vulgaris

Summary

PHAVU_002G279700, designated PvRHD2, encodes a protein containing NADPH oxidase, EF-hand, and FAD-binding domains, with NAD(P)H oxidase H2O2-forming and peroxidase activities and calcium ion binding. In French bean, this gene is associated with root epidermal cell differentiation, root development, nodulation, organogenesis, cell growth, aerobic respiration, metabolic burst, and response to ATP. It localizes to the plasmalemma, mitochondria, nucleus, plant-type vacuole, and cytosolic ribosome. PvRHD2 has been linked to root hair elongation, initiation, tip growth, and development, lateral root induction, primary and overall root growth, auxin distribution, phosphorus acquisition, cadmium tolerance, stomatal closure, microtubule organization, extracellular ATP signaling, potassium homeostasis, and cell wall strength. Related genes in other species are associated with reactive oxygen species homeostasis, salt stress response, potassium deficiency response, defense response, cell division, and gravitropism.
