The First Highly Contiguous Genome Assembly of Pikeperch (Sander lucioperca), an Emerging Aquaculture Species in Europe
<p><strong>Supporting data for "The First Highly Contiguous Genome Assembly of Pikeperch (<em>Sander lucioperca</em>), an Emerging Aquaculture Species in Europe"</strong></p> <p>===========================================================================================</p> <p><strong>Abstract:</strong></p> <p>--------</p> <p>The pikeperch (<em>Sander lucioperca</em>) is a fresh and brackish water Percid fish natively inhabiting the northern hemisphere. This species is emerging as a promising candidate for intensive aquaculture production in Europe. Specific traits like cannibalism, growth rate and meat quality require genomics based understanding, for an optimal husbandry and domestication process. Still, the aquaculture community is lacking an annotated genome sequence to facilitate genome-wide studies on pikeperch. Here, we report the first highly contiguous draft genome assembly <em>S. lucioperca</em>. In total, 413 and 66 giga base pairs of DNA sequencing raw data were generated with Illumina platform and PacBio Sequel System, respectively. The PacBio data were assembled into a final assembly size of ~900 Mb covering 89% of the 1,014 Mb estimated genome size. The draft genome consisted of 1,966 contigs ordered into 1,313 scaffolds. The contig and scaffold N50 lengths are 3.0 Mb and 4.9 Mb, respectively. The identified repetitive structures accounted for 39% of the genome. We utilized homologies to other ray-finned fishes, and ab initio gene prediction methods to predict 21,249 protein-coding genes in the <em>S. lucioperca </em>genome, of which 88% were functionally annotated by either sequence homology or protein domains and signatures search. The assembled genome spans 97.6% and 96.3% of Vertebrate respectively Actinopterygii single-copy orthologs. The outstanding mapping rate (99.9%) of genomic PE-reads on the assembly suggests an accurate and nearly complete genome reconstruction. This draft genome sequence is the first genomic resource for this promising aquaculture species. It will provide an impetus for genomic-based breeding studies targeting phenotypic and performance traits of captive pikeperch.</p> <p> </p> <p><strong>Files:</strong></p> <p>------</p> <p><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/sanlu.cds.renamed.fa">sanlu.cds.renamed.fa </a> - Coding sequences of predicted protein-coding genes </p> <p><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/sanlu.genes.filt.gff3">sanlu.genes.filt.gff3 </a> - gff3 file of predicted protein coding genes</p> <p><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/sanlu.genes.pep.fa">sanlu.genes.pep.fa </a> - predicted peptide sequences </p> <p><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/sanlu.genome.ctg.fasta">sanlu.genome.ctg.fasta </a> - <em>Sander lucioperca</em> genome assembly at contig-level</p> <p><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/sanlu.genome.scf.fa">sanlu.genome.scf.fa </a> - <em>Sander lucioperca</em> genome assembly at scaffold-level</p> <p><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/Sanlu.genome.masked.fasta">Sanlu.genome.masked.fasta </a>- Repeats-masked <em>Sander lucioperca</em> genome assembly at scaffold-level</p> <p><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/Sanlu.genome.repeats.gff">Sanlu.genome.repeats.gff </a> - Gff3 file of predicted repeats in <em>Sander lucioperca</em> genome</p> <p><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/Additional_File_2.xlsx">Additional_File_2.xlsx </a> - Functional annotations of <em>Sander lucioperca </em>genes by SwissProt, NR RefSeq, TrEMBL and InterPro databases</p> <p><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/sanlu.repeats.lib.fasta">sanlu.repeats.lib.fasta </a> - Predicted repeats library in <em>Sander lucioperca </em>in FASTA format</p> <p><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/sanlu_miRNA.csv">sanlu_miRNA.csv </a> Predicted micro RNA families in CSV tab file </p> <p><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/sanlu_miRNA.bed">sanlu_miRNA.bed </a> - Predicted micro RNA families in BED file format</p> <p><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/sanlu_miRNA.html">sanlu_miRNA.html </a><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/sanlu_miRNA.bed"> </a> - Predicted micro RNA families in HTML</p> <p><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/sanlu_rRNA.fasta">sanlu_rRNA.fasta </a> - Predicted ribosomal RNA (rRNA) sequences in FASTA file format</p> <p><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/sanlu_rRNA.gff">sanlu_rRNA.gff </a> - Predicted ribosomal RNA (rRNA) sequences in GFF file format</p> <p><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/trna.genes.csv">trna.genes.csv </a> - Predicted transfer RNA (tRNA) genes in CSV tab file</p> <p><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/SpeciesTree_rooted_node_labels.txt">SpeciesTree_rooted_node_labels.txt </a> - Predicted phylogenetic tree in NEWICK format</p> <p><a href="https://zenodo.org/api/files/808d4d80-6012-4046-bc3c-73b9792b5d8c/SpeciesTreeAlignment.fa">SpeciesTreeAlignment.fa </a> - Species tree alignment in FASTA, based on 1.1 single copy orthologs</p> <p> </p>
Data from: Population differentiation of zander (Sander lucioperca, Linnaeus, 1758) across native and newly colonized ranges suggests increasing admixture in the course of an invasion
In addition to ecological factors, evolutionary processes can determine the invasion success of a species. In particular, genetic admixture has the potential to induce rapid evolutionary change, which can result from natural or human-assisted secondary contact between differentiated populations. We studied the recent range expansion of zander in Germany focusing on the interplay between invasion and genetic admixture. Historically, the rivers Elbe and Danube harboured the most north-western source populations from which a north-westward range expansion occurred. This was initiated by introducing zander outside its native range into rivers and lakes, and was fostered by migration through artificial canals and stocking from various sources. We analysed zander populations of the native and invaded ranges using nuclear and mitochondrial genetic markers. Three genetic lineages were identified, which were traced to ancestral ranges. Increased genetic diversity and admixture in the invaded region highlighted asymmetric gene flow towards this area. We suppose that the adaptive potential of the invading populations was promoted by genetic admixture, whereas competitive exclusion in the native areas provided a buffer against introgression by novel genotypes. These explanations would be in line with evidence that hybridization can drive evolutionary change under conditions when new niches can be exploited.

Condition and size of pikeperch Sander lucioperca in Portuguese river basins
<p>We studied life-history traits focusing on growth and condition of the pikeperch <i>Sander lucioperca</i> to evaluate its phenotypic plasticity when introduced to new environments. Pikeperch is a non-native fish introduced to Iberian freshwater fauna in 1998 that quickly spread to other river basins through human-mediated activities, occupying now a wide variety of habitats along mainland Portugal. Condition (K and SMI), fork length at age, and length-weight relationships were studied for Portuguese populations. Pikeperch fork length for ages 1, 2, 3 and 4 was different between several populations. We applied generalised linear models (GLM) to study the influence of habitat type, latitude, altitude, time after first detection and fish prey richness on pikeperch populations size at age 4 and condition. We observed higher condition values on populations from lower altitudes at lentic systems more recently introduced. But higher fork length at age 4 was found in populations from higher altitudes, on older populations with higher prey richness. Habitat type, time since first detection and fish fauna composition are discussed as the main environmental factors explaining the observed phenotypic plasticity with concerns on predatory impact on native fauna.</p>
