Scientists find structural variation that boosts grain number in sorghum
Chinese scientists have uncovered two major genes responsible for sorghum’s double-grain spikelet that dramatically enhance grain number and crop yield. A substantial 35.7-kilobase intrachromosomal inversion at the DG1 (Double-Grain 1) promoter drives the upregulation of DG1 expression, leading to the development of double-grain spikelets that remarkably increase sorghum grain number while illustrating the critical role … ⌘ Read more
