Regional differences in recombination hotspots between two chicken populations [PDF]

, 2010
Background Although several genetic linkage maps of the chicken genome have been published, the resolution of these maps is limited and does not allow the precise identification of recombination hotspots. The availability of more than 3.2 million SNPs in

Linkage disequilibrium and recombination rate estimates in the self-incompatibility region of Arabidopsis lyrata [PDF]

, 2007
Genetic diversity is unusually high at loci in the S-locus region of the self-incompatible species of the flowering plant, Arabidopsis lyrata, not just in the S loci themselves, but also at two nearby loci.

Efficient gene targeting and foreign DNA removal by homologous recombination in the picoeukaryote Ostreococcus [PDF]

, 2014
With fewer than 8000 genes and a minimalist cellular organization, the green picoalga Ostreococcus tauri is one of the simplest photosynthetic eukaryotes. Ostreococcus tauri contains many plant-specific genes but exhibits a very low gene redundancy.

λ Recombination and Recombineering

EcoSal Plus, 2016
The bacteriophage λ Red homologous recombination system has been studied over the past 50 years as a model system to define the mechanistic details of how organisms exchange DNA segments that share extended regions of homology. The λ Red system proved useful as a system to study because recombinants could be easily generated by co ...

Meiotic Crossover Patterning

Frontiers in Cell and Developmental Biology, 2021
Proper number and placement of meiotic crossovers is vital to chromosome segregation, with failures in normal crossover distribution often resulting in aneuploidy and infertility.

Copy number variation, chromosome rearrangement, and their association with recombination during avian evolution [PDF]

, 2010
Chromosomal rearrangements and copy number variants (CNVs) play key roles in genome evolution and genetic disease; however, the molecular mechanisms underlying these types of structural genomic variation are not fully understood.

How to recover from a bad start: adaptation of HIV-1 transcription start site mutants during serial passaging in culture

Journal of Virology
HIV-1 uses neighboring sequences as transcription start sites and generates multiple unspliced transcripts, including two major transcripts with three guanosines (3G) or one guanosine (1G) at the 5′ end. Although only differing by 2-nt, 3G RNA and 1G RNA

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

, 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 ...

Elements in the 5′ Untranslated Region of Viral RNA Important for HIV Gag Recognition and Cross-Packaging

Viruses
During retrovirus assembly, Gag packages unspliced viral RNA as the virion genome. Genome packaging is usually specific with occasional exceptions of cross-packaging RNA from distantly related retroviruses.

Whole genome phylogenies reflect the distributions of recombination rates for many bacterial species

eLife, 2021
Although recombination is accepted to be common in bacteria, for many species robust phylogenies with well-resolved branches can be reconstructed from whole genome alignments of strains, and these are generally interpreted to reflect clonal relationships.
