Abstract:

Strawberry (Fragaria spp.) has emerged as a model system for various fundamental and applied research in recent years. In total, the genomes of five different species have been sequenced over the past ten years. Here, we report chromosome-scale reference genomes for five strawberry species, including three newly sequenced species’ genomes, and genome re-sequencing data for 128 additional accessions to estimate the genetic diversity and structure of key Fragaria species. Our analyses obtained fully resolved and strongly supported phylogenies and divergence times for most diploid strawberry species. These analyses also uncovered a new diploid species (F. emeiensis Lei). Lastly, we constructed a pan-genome for Fragaria and examined the evolutionary dynamics of gene families associated with important agronomic traits. Notably, we identified multiple independent single base mutations of the MYB10 gene associated with white pigmented fruit shared by different strawberry species. These new reference genomes and datasets, combined with our new phylogenetic estimates, should serve as a powerful comparative genomic platform and resource for future studies in strawberry.

Transcript Alignments
Transcript alignments were performed by the GDR Team of Main Bioinformatics Lab at WSU. The alignment tool 'BLAT' was used to map transcripts to the Fragaria viridis genome assembly. Alignments with an alignment length of 97% and 97% identify were preserved. The available files are in GFF3 format.
