Abstract excerpt

KEY MESSAGE: Identification of TaAGL6-B1 as the candidate gene underlying the B locus reveals its role as a key regulator of awn suppression in wheat2. A nonsynonymous substitution causes ectopic expression of TaAGL6-B1 in lemmas, repressing TaDL and inhibiting awn elongation. These findings elucidate the genetic network controlling awn development and provide molecular insight for wheat breeding. Awns are...
