ATN — Sorghum bicolor

Summary

SORBI_3005G114300 (SbATN, also known as SbTAN1) encodes a TAN1 family protein that binds microtubules and other proteins, localizing to the microtubule-associated complex, preprophase band, spindle, mitochondria, and cytosol. The gene is associated with the regulation of phragmoplast microtubule organization, phragmoplast assembly, cytokinesis by cell plate formation, embryogenesis, and NO storage. In sorghum, it has been linked to leaf coloration. Associations with division plane positioning, bird damage, seed texture, seedling vigor, pericarp color, photochemical quenching, and grain yield have also been recorded. Studies of related genes in other species link the TAN1 family to cell division plane orientation and cell division.
