Reduced meiotic recombination in rhesus macaques and the origin of the human recombination landscape.

open access: yesPLoS ONE, 2020
Characterizing meiotic recombination rates across the genomes of nonhuman primates is important for understanding the genetics of primate populations, performing genetic analyses of phenotypic variation and reconstructing the evolution of human ...

Comparative gene mapping in Arabidopsis lyrata chromosomes 6 and 7 and A thaliana chromosome IV: evolutionary history, rearrangements and local recombination rates [PDF]

open access: yes, 2006
We have increased the density of genetic markers on the Arabidopsis lyrata chromosomes AL6 and AL7 corresponding to the A. thaliana chromosome IV, in order to determine chromosome rearrangements between these two species, and to compare recombination ...

Random-sequence genetic oligomer pools display an innate potential for ligation and recombination

open access: yeseLife, 2018
Recombination, the exchange of information between different genetic polymer strands, is of fundamental importance in biology for genome maintenance and genetic diversification and is mediated by dedicated recombinase enzymes. Here, we describe an innate

ama1 genes of sympatric Plasmodium vivax and P. falciparum from Venezuela differ significantly in genetic diversity and recombination frequency. [PDF]

open access: yes, 2008
BACKGROUND: We present the first population genetic analysis of homologous loci from two sympatric human malaria parasite populations sharing the same human hosts, using full-length sequences of ama1 genes from Plasmodium vivax and P.

Identification and manipulation of the molecular determinants influencing poliovirus recombination.

open access: yesPLoS Pathogens, 2013
The control and prevention of communicable disease is directly impacted by the genetic mutability of the underlying etiological agents. In the case of RNA viruses, genetic recombination may impact public health by facilitating the generation of new viral

Hierarchical Crossover in Genetic Algorithms [PDF]

open access: yes, 1996
This paper identifies the limitations of conventional crossover in genetic algorithms when operating on two chromosomes of differing lengths. To address these problems, the concept of a Semantic Hierarchy (i.e.

Homologous Recombination in Clostridioides difficile Mediates Diversification of Cell Surface Features and Transport Systems

open access: yesmSphere, 2020
Illness caused by the pathogen Clostridioides difficile is widespread and can range in severity from mild diarrhea to sepsis and death. Strains of C. difficile isolated from human infections exhibit great genetic diversity, leading to the hypothesis that

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Single-crossover recombination and ancestral recombination trees [PDF]

open access: yes, 2011
von Wangenheim U. Single-crossover recombination and ancestral recombination trees. Bielefeld: Universität Bielefeld; 2011.Modeling the process of recombination in the deterministic limit of an infinite population leads to a large coupled nonlinear ...

Genealogy-based methods for inference of historical recombination and gene flow and their application in Saccharomyces cerevisiae [PDF]

open access: yes, 2012
Genetic exchange between isolated populations, or introgression between species, serves as a key source of novel genetic material on which natural selection can act.
