A near-complete genome assembly of Fragaria iinumae.

ABSTRACT: Fragaria iinumae, a diploid progenitor species of octoploid strawberries, likely occupies a basal position within the genus Fragaria. In this study, we report a near-complete genome assembly of F. iinumae v2.0, totaling 241.14 Mb with a contig N50 of 33.31 Mb. We identified 14 telomeric and 7 centromeric regions across its seven chromosomes. Compared to previous assemblies, F. iinumae v2.0 demonstrates substantial improvements in both genome continuity (gaps reduced from 29 to 0) and annotation completeness, including the annotation of 4,144 new genes and 395 new gene clusters. Notably, several large structural variants were identified between the F. iinumae v1.0 and F. iinumae v2.0 genomes, with most gaps in the v1.0 assembly overlapping with structural variant breakpoints.
