Sequencing of the sea lamprey (Petromyzon marinus) genome provides insights into vertebrate evolution
TLDR
Analyses of the assembly indicate that two whole-genome duplications likely occurred before the divergence of ancestral lamprey and gnathostome lineages, and help define key evolutionary events within vertebrate lineages.
The African coelacanth genome provides insights into tetrapod evolution.
TLDR
Through a phylogenomic analysis, it is concluded that the lungfish, and not the coelacanth, is the closest living relative of tetrapods.
The spotted gar genome illuminates vertebrate evolution and facilitates human-to-teleost comparisons
To connect human biology to fish biomedical models, we sequenced the genome of spotted gar (Lepisosteus oculatus), whose lineage diverged from teleosts before teleost genome duplication (TGD). The
Parsing parallel evolution: ecological divergence and differential gene expression in the adaptive radiations of thick‐lipped Midas cichlid fishes from Nicaragua
TLDR
Taken together, this case of parallelism among thick‐ and thin‐lipped cichlids shows a mosaic pattern of parallel and nonparallel evolution.
The sex-specific transcriptome of the hermaphrodite sparid sharpsnout seabream (Diplodus puntazzo)
TLDR
The aim was to characterize the expressed transcriptome of gonads and brains through RNA-Sequencing and explore the properties of genes that exhibit sex-biased expression profiles, laying the ground for understanding the complex process of sex differentiation of this economically valuable species.
The Gene Toolkit Implicated in Functional Sex in Sparidae Hermaphrodites: Inferences From Comparative Transcriptomics
TLDR
The results contribute to the understanding of the complex processes behind the establishment of the functional sex, especially in hermaphrodite species and set the groundwork for future experiments by providing a gene toolkit that can improve efforts to control phenotypic sex in finfish in the ever-increasingly important field of aquaculture.
Genomic analysis of Sparus aurata reveals the evolutionary dynamics of sex-biased genes in a sequential hermaphrodite fish
TLDR
These findings represent the first genome-wide analysis on sex-biased loci in a hermaphrodite vertebrate species, demonstrating how having two sexes in the same individual profoundly affects the fate of a large set of evolutionarily relevant genes.
Co‐orthology of Pax4 and Pax6 to the fly eyeless gene: molecular phylogenetic, comparative genomic, and embryological analyses
TLDR
It is shown that Pax4, in addition to Pax6, is a vertebrate ortholog of the fly eyeless gene (and its duplicate, twin of eyeless [toy] gene, unique to Insecta), which is merely part of a 2:2 orthology relationship between vertebrates and the fly.
The transcriptomic signature of different sexes in two protogynous hermaphrodites: Insights into the molecular network underlying sex phenotype in fish
TLDR
The transcriptomic signature of different sexes in two protogynous hermaphrodite sparids, the common pandora Pagellus erythrinus and the red porgy Pagrus pagrus, is captured in order to shed light on the molecular network contributing to either the female or the male phenotype in these organisms.
Exploring a Nonmodel Teleost Genome Through RAD Sequencing—Linkage Mapping in Common Pandora, Pagellus erythrinus and Comparative Genomic Analysis
TLDR
The common pandora linkage map showed varying degrees of conserved synteny with four other teleost genomes, namely the European seabass, Nile tilapia, stickleback, and medaka, suggesting a conserved genomic evolution in Sparidae.
