Genomic resequencing provides new insights into ecological diversification of four Saccharina Japonica varieties [PDF]

open access: yesBMC Genomics
Background  Saccharina japonica is a commercially and ecologically important seaweed and shows rapid ecological speciation. This kelp represents an excellent model for understanding the process and genetic mechanism of diversification and speciation of ...

Divergent selection drives genetic differentiation in an R2R3-MYB transcription factor that contributes to incipient speciation in Mimulus aurantiacus. [PDF]

open access: yesPLoS Genetics, 2013
Identifying the molecular genetic basis of traits contributing to speciation is of crucial importance for understanding the ecological and evolutionary mechanisms that generate biodiversity. Despite several examples describing putative "speciation genes,"

Negative global-scale association between genetic diversity and speciation rates in mammals

open access: yesNature Communications
Genetic diversity is critical for species evolution and their adaptability to global changes, while speciation rate is critical for explaining large-scale patterns of species richness. Exploring correlates of variation in genetic diversity and speciation

Cytonuclear Genetic Incompatibilities in Plant Speciation [PDF]

open access: yesPlants, 2020
Due to the endosymbiotic origin of organelles, a pattern of coevolution and coadaptation between organellar and nuclear genomes is required for proper cell function.

Genetic Links between Recombination and Speciation. [PDF]

open access: yesPLoS Genetics, 2016
Meiosis distinguishes cells in the germ line from their somatic counterparts. Part of meiosis involves a bizarre series of events in which cells deliberately damage their DNA and then repair it. Of the many double-strand breaks that are generated, a minority are resolved as reciprocal exchanges between homologous chromosomes [1].

The evolutionary genetics of speciation [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1992
The last decade has brought renewed interest in the genetics of speciation, yielding a number of new models and empirical results. Defining speciation as ‘the origin of reproductive isolation between two taxa’, we review recent theoretical studies and relevant data, emphasizing the regular patterns seen among genetic analyses.

Mating system and speciation I: Accumulation of genetic incompatibilities in allopatry.

open access: yesPLoS Genetics, 2022
Self-fertilisation is widespread among hermaphroditic species across the tree of life. Selfing has many consequences on the genetic diversity and the evolutionary dynamics of populations, which may in turn affect macroevolutionary processes such as ...

Genetics and ecological speciation [PDF]

open access: yesProceedings of the National Academy of Sciences, 2009
Species originate frequently by natural selection. A general mechanism by which this occurs is ecological speciation, defined as the evolution of reproductive isolation between populations as a result of ecologically-based divergent natural selection.

Incipient Sympatric Speciation and Evolution of Soil Bacteria Revealed by Metagenomic and Structured Non-Coding RNAs Analysis

open access: yesBiology, 2022
Soil bacteria respond rapidly to changes in new environmental conditions. For adaptation to the new environment, they could mutate their genome, which impacts the alternation of the functional and regulatory landscape.
