POD — Cucumis sativus

Summary

CSA_4G026850, designated POD and also known as CsPRX17, CsPOD, PRX17, PER17, CsPER17, encodes a secretory peroxidase with heme-binding and peroxidase activity (EC 1.11.1.7) in cucumber (Cucumis sativus) chromosome 4. The gene is associated with diverse biological processes including lignin and phenylpropanoid anabolism, melatonin anabolism, cellular respiration, response to oxidative stress, fruit development, seed germination, and the transition from vegetative to reproductive phase. It localizes to the vacuole, plant-type cell wall, and extracellular space. Associations with agronomically important traits include drought tolerance, salt tolerance, low-temperature stress tolerance, downy mildew resistance, disease tolerance, and water use efficiency. The gene is also linked to photosynthetic traits such as chlorophyll content, net photosynthetic rate, transpiration rate, and photochemical quenching, as well as root length and plant height. Studies of related genes in other species connect the family to delayed bolting, callus browning, and stress responses.
