Summary

Here we present a chromosome-scale genome of F. iinumae with a scaffold minimum scaffold length needed to cover 50% of the genome of 33.98 Mb and 23,665 protein-coding genes (see Supplementary Information). This genome was used to calculate the synonymous substitution (Ks) divergence between F. iinumae to each of the four subgenomes (Fig. 2a). This revealed that only one of the subgenomes of octoploid strawberry is F. iinumae–like, which does not support the model presented by Liston et al.5 that the origin of octoploid strawberry involved three F. iinumae–like and one F. vesca–like progenitor species. Instead, these results are consistent with our phylogenetic estimates supporting more than two diploid progenitors (Fig. 2b–d). The F. viridis (Fig. 2c) and F. nipponica (Fig. 2d) subgenomes are not F. iinumae–like.
