RHD2 — Medicago truncatula

Summary

MTR_3G098380 (RHD2) in barrel medic (Medicago truncatula) encodes a protein with NAD(P)H oxidase H2O2-forming activity, peroxidase activity, and calcium ion binding, and contains EF-hand domains. The gene is associated with root hair initiation, elongation, tip growth, formation, and growth, as well as primary root growth, lateral root induction, root growth, auxin distribution, cell wall strength, phosphorus acquisition, cadmium tolerance, stomatal closure, microtubule organization, extracellular ATP signaling, and potassium homeostasis. It is linked to nodulation, nitrogen fixation, innate immunity, cell death, metabolic burst, aerobic respiration, response to ATP, and homeostasis. Localisation evidence connects the product to the plasmalemma, nucleus, mitochondria, plant-type vacuole, and cytosolic ribosome. Studies of related genes in other species link the family to reactive oxygen species production and homeostasis, potassium deficiency and salt stress responses, cell division, and defense responses.
