摘　　要：Sorghum,a drought-resistant cereal crop crucial for global food security,typically produces single seeds per spikelet.A team of researchers from the Institute of Genetics and Developmental Biology(IGDB)of the Chinese Academy of Sciences and the Sun Yat-sen University in Guangzhou recently identified a genetic mechanism that enables some varieties to develop double-grain spikelets,significantly boosting yields.By analyzing three genetic populations,scientists traced this trait to a 35.7-kilobase chromosomal inversion activating DG1-a gene that encodes a protein regulating floral meristem development.
