Abstract
Summary Plant stature is one important factor that affects the productivity of peach orchards. However, little is known about the molecular mechanism(s) underlying the dwarf phenotype of peach tree. Here, we report a dwarfing mechanism in the peach cv. FenHuaShouXingTao ( FHSXT ). The dwarf phenotype of ‘ FHSXT ’ was caused by shorter cell length compared to the standard cv. QiuMiHong ( QMH ). ‘ FHSXT ’ contained higher endogenous GA levels than did ‘ QMH ’ and did not response to exogenous GA treatment (internode elongation). These results indicated that ‘ FHSXT ’ is a GA ‐insensitive dwarf mutant. A dwarf phenotype‐related single nucleotide mutation in the gibberellic acid receptor GID 1 was identified in ‘ FHSXT ’ ( GID 1c S191F ), which was also cosegregated with dwarf phenotype in 30 tested cultivars. GID 1c S191F was unable to interact with the growth‐repressor DELLA 1 even in the presence of GA . ‘ FHSXT ’ accumulated a higher level of DELLA 1, the degradation of which is normally induced by its interaction with GID 1. The DELLA 1 protein level was almost undetectable in ‘ QMH ’, but not reduced in ‘ FHSXT ’ after GA 3 treatment. Our results suggested that a nonsynonymous single nucleotide mutation in GID 1c disrupts its interaction with DELLA 1 resulting in a GA ‐insensitive dwarf phenotype in peach.
