ATN — Sorghum bicolor

Summary

SORBI_3004G278700, designated SbATN (also known as SbTAN1, SbATTAN, ATTAN, TAN1, ATN), encodes a TAN1 family protein on sorghum chromosome 4. The product binds microtubules and other proteins and localizes to the microtubule-associated complex, preprophase band, spindle, mitochondria, and cytosol. It is associated with the regulation of phragmoplast microtubule organization, phragmoplast assembly, cytokinesis by cell plate formation, and embryogenesis. The gene has been linked to leaf coloration, division plane positioning, and NO storage. Associations with agronomic traits include bird damage, seed texture, seedling vigor, pericarp color, photochemical quenching, and grain yield. Studies of related genes in other species link the TAN1 family to cell division plane orientation and cell division.
