PRXC2 — Asparagus officinalis

Summary

A4U43_C01F3710 (PRXC2) on asparagus chromosome 1 encodes a secretory peroxidase (EC 1.11.1.7) with heme-binding and lactoperoxidase activity. The gene is associated with hydrogen peroxide catabolic processes, response to oxidative stress, somatic embryogenesis, nodulation, and cell differentiation. Its product localises to the vacuole, plant-type cell wall, and extracellular space. Studies of related genes in other species link the family to similar oxidative and developmental roles, though these associations are not yet established in asparagus.
