The bowfin genome illuminates the developmental evolution of ray-finned fishes.

The bowfin (Amia calva) is a ray-finned fish that possesses a unique suite of ancestral and derived phenotypes, which are key to understanding vertebrate evolution. The phylogenetic position of bowfin as a representative of neopterygian fishes, its archetypical body plan and its unduplicated and slowly evolving genome make bowfin a central species for the genomic exploration of ray-finned fishes. Here we present a chromosome-level genome assembly for bowfin that enables gene-order analyses, settling long-debated neopterygian phylogenetic relationships. We examine chromatin accessibility and gene expression through bowfin development to investigate the evolution of immune, scale, respiratory and fin skeletal systems and identify hundreds of gene-regulatory loci conserved across vertebrates. These resources connect developmental evolution among bony fishes, further highlighting the bowfin's importance for illuminating vertebrate biology and diversity in the genomic era

Identification of SNP markers for population genetics studies of the Mediterranean gorgonian, Leptogorgia sarmentosa

A set of single nucleotide polymorphisms (SNP) was developed from the transcriptome of the gorgonian Leptogorgia sarmentosa. 21,491 putative SNPs were identified, and a selected set of 320 SNPs was tested using a MassARRAY System on 95 samples from the NW Mediterranean. A total of 153 SNPs were successfully genotyped and found to be polymorphic. The newly developed loci will be a valuable tool for population genetics studies of one of the most ubiquitous gorgonian species in the Mediterranean Sea

Development of a set of SNP markers for population genetics of the red gorgonian (Paramuricea clavata), an emblematic species of the Mediterranean coralligenous

Transcriptome sequencing was used for the development of single nucleotide polymorphisms (SNP) for the red gorgonian (Paramuricea clavata). A total of 20,736 SNPs were identified, and 1718 had a coverage of over 100 reads. Of the 480 SNPs tested, 347 SNPs were successfully genotyped at 95 samples from the NW Mediterranean using a MassARRAY System. This set of markers will be of great value for population genetics and phylogeography.Plateforme d'Innovation " Forêt-Bois-Fibre-Biomasse du Futur
