Abstract
Significance Strawberry is a very popular fruit. The strawberry genus ( Fragaria ) has emerged as a model system for various fundamental and applied research in recent years. Here, by using high-throughput sequencing technologies, we provide de novo whole-genome sequences for five wild strawberry species and genome resequencing data for 128 additional accessions of key species. Our analyses resulted in robust estimates of the evolutionary history for most diploid strawberry species, the discovery of a new diploid species ( Fragaria emeiensis Jia J. Lei), and the construction of a pan-genome for strawberry. We also examined the evolutionary dynamics of gene families. This study provides a powerful genomic platform and resource for future studies in strawberry.
