Summary: The integration of physical and high-density genetic maps in the assembly of the Senegalese sole genome at a chromosome-level scaffold revealed differences in genomic recombination rates between sexes and identified important sex-associated genetic loci. Analysis of sex markers showed incomplete penetrance with males as the heterogametic sex. Comparison with other Pleuronectiformes genomes also revealed chromosomal rearrangements, including a lineage-specific Robertsonian fusion in S. senegalensis.

Summary: In this study, hox gene clusters in the Senegalese sole were characterized to better understand the developmental and metamorphosis process in this species. Cytogenetic analysis revealed the localization of hox genes on specific chromosomes. Comparative and phylogenetic analysis showed conserved organization within each hox cluster, but different clustering patterns between clusters. Analysis of structural and repetitive sequences identified polymorphisms mediated by repetitive elements in the hoxba gene cluster, suggesting a possible loss of the hoxb7a gene in the Pleuronectiformes lineage. This work provides insights into the organization and regulation of hox clusters, and serves as a foundation for further studies on expression patterns.

Summary: This study evaluated the presence of vertebral anomalies in postlarvae and juvenile Senegalese sole fed with Artemia spp. metanauplii enriched with four commercial products. The results showed a high percentage of individuals with skeletal anomalies in every dietary group, and some variations in the frequency of anomalies among diets were noted. However, it was not possible to establish a clear effect of the enrichment products on the development of vertebral deformities due to the masking effect of other rearing conditions.

Summary: Rising levels of atmospheric CO2 are causing ocean warming and acidification, which have potential negative effects on commercially important fish species. This study examined the effects of ocean acidification (OA) and warming (OW), both individually and combined, on the composition, fitness, and energy budget of juvenile Senegalese sole. The results showed that acidification and warming did not significantly impact the proximate composition and gross energy of the fish. However, OA, OW, and OAW treatments resulted in higher growth rates, metabolic rates, and energy intake compared to control conditions. The study highlights the physiological responses of juvenile Senegalese sole to ocean warming and acidification, emphasizing the importance of understanding the impact of climate change on fisheries.

Summary: This study reports a novel molecular sexing tool, which identified 41 single nucleotide polymorphism variants in the follicle stimulating hormone receptor (fshr) gene through whole genome resequencing of six males and six females, and validated the sex association. The study also found differential expression of the fshr gene between male and female gonads at an early stage of gonadal differentiation, suggesting a mechanism hampering the action of the follicle stimulating hormone driving the undifferentiated gonad toward testis.

Summary: In this study, the similarity of X and Y chromosomes in four Omophoita species was examined, and genomic differentiation was compared to better understand the evolutionary process of the giant sex chromosomes. The results showed significant genomic similarity between the sexes and a sex-specific region on the Y chromosome, as well as genomic divergence between species. However, whole chromosome painting experiments revealed high intra- and interspecific similarity of the sex chromosomes in O. octoguttata. Our data support a common origin and canonical evolution of the sex chromosomes in this group, as they have high genomic similarity between them.

Summary: The study investigates the chromosomal rearrangements and associated synteny blocks in the origin of a multiple X1X2Y sex chromosome system in the Neotropical catfish genus Harttia. The results suggest that the X1X2Y sex chromosome systems in H. punctata, H. duriventris and H. villasboas represent the same linkage groups which also form the putative XY sex chromosomes of H. rondoni. The study also indicates that the X1X2Y sex chromosome system may have formed through an X chromosome fission rather than a previously proposed Y-autosome fusion.

Summary: This study analyzed the distribution of microsatellites in the holocentric chromosomes of Triatominae, which are vectors of Chagas disease. The results showed that there are differences in microsatellite distribution between Triatomini and Rhodniini species, with higher abundance and diversity in Triatomini. Additionally, a high abundance of GATA repeats was found in the Y chromosome of all Triatomini species, suggesting it is an ancestral trait specific to Triatomini.

Summary: MicroRNAs play crucial roles in regulating gene expression, and the miR-430 family is particularly important in early fish development. This study found that the miR-430 family emerged early in fish evolution, and all studied species have multiple copies of miR-430. In some early-diverged fish, three different versions of miR-430 were identified, but some groups seem to have lost some of these versions over time. These findings suggest the need for further research on the functions of different miR-430 versions and their potential impact on aquaculture.

Summary: In this study, the dynamics of satellite DNAs (SatDNAs) accumulation and elimination during W chromosome differentiation in Triportheus fish were investigated. The majority of repetitive sequences were eliminated as speciation occurred in five additional Triportheus species. While the W chromosomes continued to degenerate, the Z chromosomes in some species began to accumulate TauSatDNAs. Species-specific SatDNAs were likely amplified in the heterochromatic regions of both Z and W chromosomes in each species. Thus, the W chromosomes of various Triportheus species underwent significant evolutionary changes within a short period of time (15-25 Myr) after divergence.

Summary: Chromosomal rearrangements play a significant role in the evolution of fish genomes, and satellite DNA sequences have potential relevance in both sex and karyotype evolution. This study investigated the association of satDNAs with chromosome-shuffling events and their involvement in the evolution of sex chromosomes in Pyrrhulina fish. In addition, a large collection of satDNAs for both species was characterized for the first time, and their potential involvement in karyotype evolution was demonstrated.
