Wheat IDD5 and barley SDW3, orthologous zinc-finger transcription factors, bind DELLA proteins and promote gibberellin (GA)-driven elongation; their loss-of-function mutants are GA-insensitive semi-dwarfs resembling Rht-D1b.

The paper develops a wheat haplotype graph database for efficient genotype storage and imputation, showing improved accuracy over existing methods.

The paper identifies wheat ASN2 gene knockouts that reduce free asparagine in grain by 9-34%, without affecting quality or agronomic traits, enabling acrylamide reduction in wheat breeding.
