POX — Capsicum annuum

Summary

CaPOX (T459_05761) on pepper chromosome 2 encodes a secretory haem peroxidase (EC 1.11.1.7) with lactoperoxidase and peroxidase activity, heme binding, and metal binding. The product is localised to the plant-type cell wall and extracellular space. CaPOX is associated with cellular respiration, hydrogen peroxide catabolism, induced systemic resistance, nitric oxide storage, nodulation, and response to oxidative stress. It is linked to relative chlorophyll content, chlorophyll content, photosynthetic rate, and respiration rate. Related genes in other species are associated with traits including drought recovery, drought sensitivity, leaf chlorophyll content, quantum yield, fruit firmness, rooting depth, root volume, shoot and root fresh and dry weights, stem length and diameter, leaf length, leaf water potential, leaf relative water content, plant fresh weight, relative growth rate, ear length, rhizome formation, cell membrane stability, and contents of ash, potassium, selenium, carbohydrate, soluble protein, flavonoid, and proline.
