Haplotype-resolved chromosome-level genome assemblies of nineteen apple (Malus domestica Borkh.) cultivars.

ABSTRACT: Apple (Malus domestica Borkh.) is a major fruit crop with a rich genetic history shaped by whole-genome duplication, domestication, and selective breeding. Discovering apple genetic diversity through genome sequencing provides new opportunities to improve disease resistance, environmental adaptation, and fruit quality. Here, we present 19 haplotype-resolved genome assemblies of apple, sequenced using PacBio HiFi reads with approximately 30 × coverage. Each haplome assembly has a mean length of 675.3 Mb and contains on average 47,445 annotated protein-coding genes. These haplome assemblies have a high completeness, with mean complete BUSCO scores of 98.8%. We identified 578 previously uncharacterized orthogroups shared across all 38 haplomes, indicating that these assemblies capture novel g
