Abstract
BackgroundThe Glanville fritillary (Melitaea cinxia) butterfly is a model system for metapopulation dynamics research in fragmented landscapes. Here, we provide a chromosome-level assembly of the butterfly's genome produced from Pacific Biosciences sequencing of a pool of males, combined with a linkage map from population crosses.ResultsThe final assembly size of 484 Mb is an increase of 94 Mb on the previously published genome. Estimation of the completeness of the genome with BUSCO indicates that the genome contains 92–94% of the BUSCO genes in complete and single copies. We predicted 14,810 genes using the MAKER pipeline and manually curated 1,232 of these gene models.ConclusionsThe genome and its annotated gene models are a valuable resource for future comparative genomics, molecular biology, transcriptome, and genetics studies on this species.
Highlights
The Glanville fritillary (Melitaea cinxia) butterfly is a model system for metapopulation dynamics research in fragmented landscapes
The distance to the nearest M. cinxia population across the water is 5 km, and we assume that the introduced population has remained completely isolated
Fountain et al [17] demonstrated that samples from the Sottunga population separate clearly from samples collected on the mainland
Summary
The Glanville fritillary (Melitaea cinxia) butterfly is a model system for metapopulation dynamics research in fragmented landscapes. This manual work facilitated the removal of additional haplotype contigs and regions and resulted in the haploid reference genome sequence including start and end positions of contigs in the correct order and orientation for each chromosome.
