PRX40 — Cicer arietinum

Summary

LOC101497891 (CaPRX40) on chickpea chromosome 7 encodes a secretory haem peroxidase with lactoperoxidase and peroxidase activities, binding heme and metal ions. The gene is associated with hydrogen peroxide catabolism, response to oxidative stress, immune response, anther wall tapetum development, chromatin modelling, and homeostasis. Its product localises to the plant-type cell wall and extracellular space. CaPRX40 is associated with salt tolerance, pollen development, male fertility, cell wall integrity, and tapetal cell wall integrity. Related genes in other species are linked to pollen fertility restoration.
