ATP6 — Sorghum bicolor

Summary

SORBI_3003G120900 (SbATP6) on sorghum chromosome 3 encodes a secretory class III peroxidase (EC 1.11.1.7) with haem-binding and lactoperoxidase activity. The gene is associated with cell wall polysaccharide breakdown, plant-type cell wall modification, lignin anabolism, and hydrogen peroxide catabolism, as well as anther wall tapetum development, nodulation, and responses to oxidative stress and other organisms. It is linked to cytoplasmic male sterility, photosynthetic rate, peroxidase-71 content, and associations including seed coat mucilage extrusion, pollen development, male fertility, and tapetal cell wall integrity. The encoded protein localises to the vacuole, plant-type cell wall, and extracellular space. Related genes in other species are linked to lignin biosynthesis, secondary cell wall thickness, drought tolerance, seed germination, and root morphology.
