Banana bunchy top virus genetic diversity in Pakistan and association of diversity with recombination in its genomes.

PLoS ONE, 2022
Banana Bunchy top virus (BBTV) is a multipartite circular single strand DNA virus that belongs to genus Babuvirus and family Nanoviridae. It causes significant crop losses worldwide and also in Pakistan.

The Genetic Architecture of Natural Variation in Recombination Rate in Drosophila melanogaster. [PDF]

PLoS Genetics, 2016
Meiotic recombination ensures proper chromosome segregation in many sexually reproducing organisms. Despite this crucial function, rates of recombination are highly variable within and between taxa, and the genetic basis of this variation remains poorly ...

Genetic analysis of genome-scale recombination rate evolution in house mice. [PDF]

PLoS Genetics, 2011
The rate of meiotic recombination varies markedly between species and among individuals. Classical genetic experiments demonstrated a heritable component to population variation in recombination rate, and specific sequence variants that contribute to ...

Effect of recombination on genetic diversity of Caenorhabditis elegans

Scientific Reports, 2023
Greater molecular divergence and genetic diversity are present in regions of high recombination in many species. Studies describing the correlation between variant abundance and recombination rate have long focused on recombination in the context of ...

Similarity in recombination rate estimates highly correlates with genetic differentiation in humans. [PDF]

PLoS ONE, 2011
Recombination varies greatly among species, as illustrated by the poor conservation of the recombination landscape between humans and chimpanzees. Thus, shorter evolutionary time frames are needed to understand the evolution of recombination.

Genome-wide recombination variation in biparental segregating and reciprocal backcross populations provides information for introgression breeding in Brassica napus

Crop Journal, 2023
Variation in patterns of recombination in plant genomes provides information about species evolution, genetic diversity and crop improvement. We investigated meiotic crossovers generated in biparental segregating and reciprocal backcross populations of ...

Genetic variants in REC8, RNF212, and PRDM9 influence male recombination in cattle. [PDF]

PLoS Genetics, 2012
We use >250,000 cross-over events identified in >10,000 bovine sperm cells to perform an extensive characterization of meiotic recombination in male cattle.
