De novo genome assembly, inversion detection, and worldwide adaptation on the invasive species Styela plicata.

ABSTRACT: Biological invasions are a major threat to biodiversity. However, genomic resources of invasive species are scarce, compromising the study of their invasive success and our ability to mitigate their effects. Here, we assemble and annotate the reference chromosome-level genome of the invasive ascidian Styela plicata, and complement it with whole genome sequencing data from 24 individuals worldwide. We developed and validated the novel method "individual Detection of linkage by Genotyping" (iDlG), that allowed identifying four large chromosomal inversions and assigning karyotypes at the individual level. The four inversions are polymorphic throughout the species' distribution range and are enriched with genes that potentially influence fitness in estuarine and harbor environments, where Stye
