Chinese scientists find structural variation that boosts grain number in sorghum

Researchers have uncovered two major genes responsible for sorghum's double-grain spikelet, leading to a significant increase in grain number and crop yield. The study found that the DG1 gene regulates floret meristem formation and differentiation, restoring fertility to the lower floret and resulting in the double-grain trait.
