PRX2 — Cucumis sativus

Summary

CsPRX2 (CSA_6G495000) on cucumber chromosome 6 encodes a secretory peroxidase (EC 1.11.1.7) with peroxidase activity, heme binding, and protein phosphorylated amino acid binding. The gene is associated with hydrogen peroxide catabolic process, response to stress, response to oxidative stress, abscisic acid signaling, brassinosteroid mediated signaling, defence response to fungi, and virus-induced PTGS. It is associated with root hair growth, root elongation, hypocotyl elongation, lignin biosynthesis, nitrate uptake, leaf composition trait, seedling growth and development trait, cell proliferation, organ identity, and vegetative growth. The encoded peroxidase localises to the plant-type cell wall, vacuole, Golgi complex, mitochondria, cytosol, and extracellular space. Studies of related genes in other species link the family to root hair length, organ size, and calcium signaling.
