POD — Asparagus officinalis

Summary

A4U43_C03F12700 (POD) on asparagus chromosome 3 encodes a secretory peroxidase, a haem-binding enzyme classified as EC 1.11.1.7 with lactoperoxidase and peroxidase activities. The gene is associated with hydrogen peroxide catabolism, lignin anabolism, and responses to oxidative stress and salt stress, and has been linked to signal transduction. The encoded protein localises to the vacuole, plant-type cell wall, and extracellular space. Associations with chlorophyll content and salt stress response have also been noted. Related genes in other species, such as HRPC2 and TOPA, connect the broader peroxidase family to similar oxidative and stress-related processes.
