The genome sequence of the woodland strawberry (Fragaria vesca L.) is an important resource providing a reference for comparative genomics studies and future sequenced rosaceous species and has great utility as a model for the development of markers for mapping in the cultivated strawberry Fragaria ×ananassa Duchesne ex Rozier. A set of 152 microsatellite simple sequence repeat (SSR) primer pairs was developed and mapped, along with 42 previously published but unmapped SSRs, permitting the precise assignment of 28.2 Mbp of previously unanchored genome sequence scaffolds (13% of the F. vesca genome sequence). The original ordering of F. vesca sequence scaffolds was performed without a physical map, using predominantly SSR markers to order scaffolds via anchoring to a comprehensive linkage map. This report complements and expands resolution of the Fragaria spp. reference map and refines the scaffold ordering of the F. vesca genome sequence using newly devised tools. The results of this study provide two significant resources: (i) the concurrent validation of a substantial set of SSRs associated with these previously unmapped regions of the Fragaria spp. genome and (ii) the precise placement of previously orphaned genomic sequence. Together, these resources improve the resolution and completeness of the strawberry genome sequence, making it a better resource for downstream studies in Fragaria spp. and the family Rosaceae.

Abstract

The genome sequence of the woodland strawberry (Fragaria vesca L.) is an important resource providing a reference for comparative genomics studies and future sequenced rosaceous species and has great utility as a model for the development of markers for mapping in the cultivated strawberry Fragaria ×ananassa Duchesne ex Rozier. A set of 152 microsatellite simple sequence repeat (SSR) primer pairs was developed and mapped, along with 42 previously published but unmapped SSRs, permitting the precise assignment of 28.2 Mbp of previously unanchored genome sequence scaffolds (13% of the F. vesca genome sequence). The original ordering of F. vesca sequence scaffolds was performed without a physical map, using predominantly SSR markers to order scaffolds via anchoring to a comprehensive linkage map. This report complements and expands resolution of the Fragaria spp. reference map and refines the scaffold ordering of the F. vesca genome sequence using newly devised tools. The results of this study provide two significant resources: (i) the concurrent validation of a substantial set of SSRs associated with these previously unmapped regions of the Fragaria spp. genome and (ii) the precise placement of previously orphaned genomic sequence. Together, these resources improve the resolution and completeness of the strawberry genome sequence, making it a better resource for downstream studies in Fragaria spp. and the family Rosaceae.
