Evidence of widespread degradation of gene control regions in hominid genomes [PDF]

, 2004
Although sequences containing regulatory elements located close to protein-coding genes are often only weakly conserved during evolution, comparisons of rodent genomes have implied that these sequences are subject to some selective constraints ...

Experimental evolution supports signatures of sexual selection in genomic divergence

Evolution Letters, 2021
Comparative genomics has contributed to the growing evidence that sexual selection is an important component of evolutionary divergence and speciation. Divergence by sexual selection is implicated in faster rates of divergence of the X chromosome and of ...

Parallelism in eco-morphology and gene expression despite variable evolutionary and genomic backgrounds in a Holarctic fish.

PLoS Genetics, 2020
Understanding the extent to which ecological divergence is repeatable is essential for predicting responses of biodiversity to environmental change. Here we test the predictability of evolution, from genotype to phenotype, by studying parallel evolution ...

Tandem duplicate expression patterns are conserved between maize haplotypes of the α‐zein gene family

Plant Direct, 2021
Tandem duplication gives rise to copy number variation and subsequent functional novelty among genes as well as diversity between individuals in a species.

The Divergence of the Viscosity of a Fluid of Hard Spheres as an Indicator for the Fluid-Solid Phase Transition [PDF]

, 1987
Solution of the Kirkwood-Smoluchowski equation for a hard sphere fluid yields an expression for the viscosity which shows a dramatic pretransitional increase and a divergence at a number density close to that one observed in computer simulations and in ...

Rapid functional divergence after small-scale gene duplication in grasses

BMC Evolutionary Biology, 2019
Background Gene duplication has played an important role in the evolution and domestication of flowering plants. Yet little is known about how plant duplicate genes evolve and are retained over long timescales, particularly those arising from small-scale

RNA-Seq Analysis Reveals Expression Regulatory Divergence of W-Linked Genes between Two Contrasting Chicken Breeds

Animals, 2022
The regulation of gene expression is a complex process involving organism function and phenotypic diversity, and is caused by cis- and trans- regulation.

Quantum $f$-divergences in von Neumann algebras I. Standard $f$-divergences

, 2018
We make a systematic study of standard $f$-divergences in general von Neumann algebras. An important ingredient of our study is to extend Kosaki's variational expression of the relative entropy to an arbitary standard $f$-divergence, from which most of ...

Physiopathological Implications of 7TM Receptors [PDF]

, 2010
Seven-transmembrane (7TM) receptors are one of the most important proteins involved in perception of extracellular stimuli and regulation of variety of intracellular signaling pathways.
