Abstract

The horizontal transmission of lymphocystis disease virus (LCDV) through contaminated water and feed (using artemia as vehicle) and the associated immune gene expression profiles in Senegalese sole post-larvae were investigated. All specimens analyzed were positive for LCDV DNA detection at 1-day post-challenge (1 dpc) with the highest viral levels in specimens infected through the immersion route. However, the percentage of LCDV-positive animals and number of viral DNA copies dropped progressively at 2 and 7 dpc. The histological analysis identified structural changes in the skin, muscle and gills of sole post-larvae LCDV-challenged by immersion. In situ hybridization confirmed a wide distribution of LCDV in the skin, gut, surrounding vessels in trunk muscle and head kidney in the immersion route, while the signals were restricted to the liver and lamina propria in the feeding treatment. Expression analysis using a set of 22 genes related to innate immune defense system demonstrated clear differences in the time-course response to LCDV as function of the infection route. Most antiviral defense genes, the proinflammatory cytokines, the complement c3, g-type lysozyme and T-cell markers cd4 and cd8a were rapidly induced in the feeding-infected post-larvae, and they were remained activated at 2 dpc. In contrast, in the immersion-infected post-larvae the induction of most defensive genes was delayed, with a low intensity at 2 dpc. All these data demonstrate that LCDV can horizontally infect Senegalese sole post-larvae through the water or feed although with different patterns of histopathological disorders, virus distribution and route-specific expression profiles.

Abstract

The integration of physical and high-density genetic maps is a very useful approach to achieve chromosome-level genome assemblies. Here, the genome of a male Senegalese sole (Solea senegalensis) was de novo assembled and the contigs were anchored to a high-quality genetic map for chromosome-level scaffolding. Hybrid assembled genome was 609.3 Mb long and contained 3403 contigs with a N50 of 513 kb. The linkage map was constructed using 16,287 informative SNPs derived from ddRAD sequencing in 327 sole individuals from five families. Markers were assigned to 21 linkage groups with an average number of 21.9 markers per megabase. The anchoring of the physical to the genetic map positioned 1563 contigs into 21 pseudo-chromosomes covering 548.6 Mb. Comparison of genetic and physical distances indicated that the average genome-wide recombination rate was 0.23 cM/Mb and the female-to-male ratio 1.49 (female map length: 2,698.4 cM, male: 2,036.6 cM). Genomic recombination landscapes were different between sexes with crossovers mainly concentrated toward the telomeres in males while they were more uniformly distributed in females. A GWAS analysis using seven families identified 30 significant sex-associated SNP markers located in linkage group 18. The follicle-stimulating hormone receptor appeared as the most promising locus associated with sex within a region with very low recombination rates. An incomplete penetrance of sex markers with males as the heterogametic sex was determined. An interspecific comparison with other Pleuronectiformes genomes identified a high sequence similarity between homologous chromosomes, and several chromosomal rearrangements including a lineage-specific Robertsonian fusion in S. senegalensis.
