ATP6 — Oryza sativa Indica Group

Summary

BGIOSGA003712 (ATP6, also known as OiPRX9, OiPRX5, OiPRX17, PRX9, ATP6, PER36, OiPER36, OiPER9, OiPRX72, PRX17, PRX36, PRX54) on chromosome 1 of Indica rice encodes a haem peroxidase with lactoperoxidase and peroxidase activity, classified under EC 1.11.1.7. The gene is associated with regulation of mitochondrial gene expression, RNA metabolism, cell wall polysaccharide breakdown, plant-type cell wall modification, mucilage extrusion from seed coat, anther wall tapetum development, lignin anabolism, nodulation, response to oxidative stress, and response to other organisms. It is linked to vacuole, plant-type cell wall, and extracellular localisation. Associations include cytoplasmic male sterility, heterosis, photosynthetic rate, peroxidase-71 content, pollen development, male fertility, tapetal cell wall integrity, seed coat mucilage extrusion, and cold stress. Studies of related genes in other species link the family to lignin biosynthesis and secondary cell wall thickness.
