Conclusions
The chromosome-level assembly of D. silvatica is the first high-quality continuous genome of a representative of the Synspermiata clade, one of the major evolutionary lineages within spiders. This new assembly will contribute to alleviate the scarce representation of spiders and chelicerates genomes within the tree of life while represents a very useful resource to rightly characterize structural variants, repetitive elements and large gene families involved in relevant biological functions in spiders, such as, for example, those encoding chemosensory system proteins and venom components. An immediate application will be the comprehensive evolutionary analysis of these genomic variants beyond single nucleotide changes to elucidate the genomic regions and the mechanisms underlying the remarkable adaptive radiation of the genus Dysdera in Canary Islands.
