ATP6 — Oryza sativa Indica Group

Summary

BGIOSGA001948 (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 activities (EC 1.11.1.7). This gene is associated with regulation of mitochondrial gene expression, RNA metabolism, cell wall modification, mucilage extrusion from seed coat, anther wall tapetum development, lignin anabolism, nodulation, and responses to oxidative stress and other organisms. It is linked to cytoplasmic male sterility, heterosis, photosynthetic rate, and peroxidase-71 content. The encoded protein localises to the vacuole, plant-type cell wall, and extracellular space. Studies of related genes in other species connect the family to lignin biosynthesis, secondary cell wall thickness, and fluoranthene accumulation.
