Geographic distribution and phylogeny of seven diploid Fragaria species and outgroup species. (Upper Left) Geographic distribution of seven diploid Fragaria species with available reference genomes from this and our previous study (15, 16). Mapped ranges are adapted from Global Biodiversity Information Facility, Chinese Virtual Herbarium, and our own collections. (Lower Right) The phylogenetic tree of Rosales with three species (C. sativa, M. notabilis Z. jujuba) used as outgroups. The estimated divergence times are shown above branch nodes. Red dots mark the fossil calibration points used to estimate the divergence times.
