PRX32 — Brassica oleracea

Summary

BoPRX32, the cabbage (Brassica oleracea) gene on chromosome 9, encodes a secretory haem peroxidase with lactoperoxidase and peroxidase activity, and binds heme and metal ions. The encoded protein is localised to the vacuole, plant-type cell wall, and extracellular space. BoPRX32 is associated with regeneration, hydrogen peroxide catabolic processes, carbohydrate metabolism, response to oxidative stress, and salinity response. It is associated with shoot dry weight, plant height, and salt tolerance. Related genes in other species are linked to salt tolerance and salt stress sensitivity with reduced root length.
