An Aneuploidy-Free and Structurally Defined Balancer Chromosome Toolkit for Caenorhabditis elegans

Cell Reports, 2018
Summary: Balancer chromosomes are critical tools for genetic research. In C. elegans, reciprocal translocations that lead to aneuploidy have been widely used to maintain lethal and sterile mutations in stable stocks.

A universal method for automated gene mapping [PDF]

, 2005
Small insertions or deletions (InDels) constitute a ubiquituous class of sequence polymorphisms found in eukaryotic genomes. Here, we present an automated high-throughput genotyping method that relies on the detection of fragment-length polymorphisms ...

Crossing over...Markov meets Mendel. [PDF]

PLoS Computational Biology, 2012
Chromosomal crossover is a biological mechanism to combine parental traits. It is perhaps the first mechanism ever taught in any introductory biology class.

Integration of DNA into bacterial chromosomes from plasmids without a counter-selection marker. [PDF]

, 2011
Most bacteria can only be transformed with circular plasmids, so robust DNA integration methods for these rely upon selection of single-crossover clones followed by counter-selection of double-crossover clones.

Manipulation of crossover frequency and distribution for plant breeding

Theoretical and Applied Genetics, 2018
The crossovers (COs) that occur during meiotic recombination lead to genetic diversity upon which natural and artificial selection can act. The potential of tinkering with the mechanisms of meiotic recombination to increase the amount of genetic ...

The genomics of speciation in Drosophila: diversity, divergence, and introgression estimated using low-coverage genome sequencing.

PLoS Genetics, 2009
In nature, closely related species may hybridize while still retaining their distinctive identities. Chromosomal regions that experience reduced recombination in hybrids, such as within inversions, have been hypothesized to contribute to the maintenance ...

Broad-scale recombination pattern in the primitive bird Rhea americana (Ratites, Palaeognathae). [PDF]

PLoS ONE, 2017
Birds have genomic and chromosomal features that make them an attractive group to analyze the evolution of recombination rate and the distribution of crossing over.

Double-strand break repair and homologous recombination in Schizosaccharomyces pombe [PDF]

, 2006
In recent years our understanding of double strand break repair and homologous recombination in Schizosaccharomyces pombe has increased significantly, and the identification of novel pathways and genes with homologues in higher eukaryotes has increased ...

SMC is recruited to oriC by ParB and promotes chromosome segregation in Streptococcus pneumoniae [PDF]

, 2011
Segregation of replicated chromosomes is an essential process in all organisms. How bacteria, such as the oval-shaped human pathogen Streptococcus pneumoniae, efficiently segregate their chromosomes is poorly understood.

The Number of Meiotic Double-Strand Breaks Influences Crossover Distribution in Arabidopsis[OPEN]

The Plant Cell, 2018
Analysis of a spo11-1 hypomorphic allele in Arabidopsis showed that reducing the number of meiotic DSBs resulted in a profound redistribution of meiotic crossovers on a genome-wide scale.
