摘 要：Fragaria vesca,commonly known as wild or woodland strawberry,is the most widely distributed diploid Fragaria species and is native to Europe and *** of its small plant size,low heterozygosity,and relative ease of genetic transformation,*** has been a model plant for fruit research since the publication of its Illumina-based genome in ***,its genomic contribution to octoploid cultivated strawberry remains a long-standing ***,we de novo assembled and annotated a telomere-to-telomere,gap-free genome of ***‘Hawaii 4’,with all seven chromosomes assembled into single contigs,providing the highest completeness and assembly quality to *** gap-free genome is 220785082 bp in length and encodes 36173 protein-coding gene models,including 1153 newly annotated *** 14 telomeres and seven centromeres were annotated within the seven *** the three previously recognized wild diploid strawberry ancestors,***,***,and ***,phylogenomic analysis showed that *** and *** are the ancestors of the cultivated octoploid strawberry F.×ananassa,and *** is its closest *** subgenomes of F.×ananassa belong to the *** group,and one is sister to *** anticipate that this high-quality,telomere-to-telomere,gap-free *** genome,combined with our phylogenomic inference of the origin of cultivated strawberry,will provide insight into the genomic evolution of Fragaria and facilitate strawberry genetics and molecular breeding.
