TLDR
A recent overview of genomics data, address different approaches applicable to comparative genomics analyses, and illustrate these comparisons to better understand the complex mechanisms under the vertebrate genomes as mentioned in this paper, and summarize the applications in chromosomes research and cytogenomics.
Abstract
The living fishes span a unique and interesting set of animals because of their vast diversity, morphology, ecology, genetics and genomics, and higher importance to biology, economy and culture. During the past decade, the remarkable increase in fish genome sequencing has revolutionized comparative and evolutionary genomics, with the outcome of stimulating insights into vertebrate genome biology. Fish genomics has been transformed rapidly, with the availability of high-quality chromosome level genome assemblies and large collections of sequencing datasets, which are roadmaps for striking discoveries. Landmark achievements are being made; such as the accomplishment of fully assembled lungfish genome which is biggest genome ever sequenced. Here, we highlight current developments in vertebrate’s comparative genomics and discuss how fish genomes could be considered as vital resources for genomic studies. We present a recent overview of genomics data, address different approaches applicable to comparative genomics analyses, and illustrate these comparisons to better understand the complex mechanisms under the vertebrate genomes. We also summarize the applications in chromosomes research and cytogenomics.

Fish as Model Systems to Study Epigenetic Drivers in Human Self-Domestication and Neurodevelopmental Cognitive Disorders

TL;DR: It is argued that fish provide model systems to study epigenetic drivers in human self-domestication and will pave the way for future studies using fish as models to investigate epigenetic changes as drivers of human-self domestication and as triggers of cognitive disorders.

Integration of Maps Enables a Cytogenomics Analysis of the Complete Karyotype in Solea senegalensis

TL;DR: Differences in the distribution and abundance of repetitive elements in chromosomes that have undergone remodeling processes during the course of evolution also suggest a possible role for simple repeat sequences in rearranged regions.

Fish as model systems to study epigenetic drivers in human self-domestication and neurodevelopmental cognitive disorders

TL;DR: In this paper , the authors compare genes that carry epigenetic changes in early domesticates of European sea bass with anatomically modern humans and neurodevelopmental cognitive disorders with abnormal self-domestication traits, i.e., schizophrenia, Williams syndrome and autism spectrum disorders.

Genome size estimation and its associations with body length, chromosome number and evolution in teleost fishes.

TL;DR: In this paper , the authors examined the relationship between the genome size, chromosome number and body length across all fishes and found that body length was associated with genome size whereas no relationship was noticed between the GS and the chromosome number.

Whole-genome duplications in the ancestral vertebrate are detectable in the distribution of gene family sizes of tetrapod species.

TL;DR: It is concluded that the deviation from the power-law that is observed in the empirical data is the result of the two whole-genome duplications that occurred in the ancestral chordate, which implies that the two ancient WGDs continue to have a structural effect on gene families approximately 500 million years after the initial events.

Integrating cytogenetics and genomics in comparative evolutionary studies of cichlid fish

TL;DR: There is evidence that large syntenic chromosome segments have been maintained conserved during evolution, at least for the considered markers in cichlid fishes.

The genomic timeline of cichlid fish diversification across continents.

TL;DR: These results support cichlid diversification long after the breakup of the supercontinent Gondwana and lay the foundation for precise temporal reconstructions of the exceptional continental cICHlid adaptive radiations.

Evolution of signal transduction by gene and genome duplication in fish.

TL;DR: Observations validate fish as an outstanding model to study the mechanisms and biological consequences of gene and genome duplication but underline the complexity of the fish model and the caution necessary in transferring knowledge from fish to higher vertebrates and vice versa.
