Data from: De Novo Genome assembly of the Caucasian dwarf goby Knipowitschia cf. caucasica, a new alien Gobiidae invading the River Rhine

Background (Abstract from Paper)

The Caucasian dwarf goby Knipowitschia cf. caucasica is a new invasive alien Gobiidae spreading in theLower Rhine since 2019. Little is known about the invasion biology of the species and further investiga-tions to reconstruct the invasion history are lacking genomic resources. We assembled a high-qualitychromosome-scale reference genome of Knipowitschia cf. caucasica by combining PacBio, Omni-C andIllumina technologies. The size of the assembled genome is 956.58 Mb with a N50 scaffold length of 43 Mb,which includes 92.3 % complete vertebrate/Actinopterygii Benchmarking Universal Single-Copy Orthologs.98.96 % of the assembly sequence was assigned to 23 chromosome-level scaffolds, with a GC-content of42.83 %. Repetitive elements account for 53.08 % of the genome. The chromosome-level genome contained49,622 transcripts with 42,926 multi-exons, of which 45,512 genes were functionally annotated. In summary,the high-quality genome assembly provides a fundamental basis to understand the adaptive advantage ofthe species.The file provided here is the non-redundant repeat library (2,812 consensus sequences of repeat families). 

Method: Repetitive elements were identified de novo with RepeatModeler version 2.0.1. Repetitive DNA and soft-masking was performed with RepeatMasker version 4.1.1 (Smit et al., 2013) using the repeat library previously identified via RepeatModeler and skipping the bacterial insertion element check (-no_is) and run with rmblastn version 2.10.0+ (Flynn et al., 2020).
