«The Mechanism of Mendelian Heredity» (The 100th anniversary of the first publication of the book by the group of T.H. Morgan)

open access: yesВавиловский журнал генетики и селекции, 2015
The article is dedicated to the 100th anniversary of the first Morgan’s book, «The Mechanism of Mendelian Heredity» in 1915. The book presented the program of Morgan’s genetic research. The necessity of this article stems from the fact that T.H.

Fine scale analysis of crossover and non-crossover and detection of recombination sequence motifs in the honeybee (Apis mellifera). [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Meiotic exchanges are non-uniformly distributed across the genome of most studied organisms. This uneven distribution suggests that recombination is initiated by specific signals and/or regulations.

Modulating Crossover Frequency and Interference for Obligate Crossovers in Saccharomyces cerevisiae Meiosis

open access: yesG3: Genes, Genomes, Genetics, 2017
Meiotic crossover frequencies show wide variation among organisms. But most organisms maintain at least one crossover per homolog pair (obligate crossover). In Saccharomyces cerevisiae, previous studies have shown crossover frequencies are reduced in the

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

open access: yes, 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 ...

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

open access: yesCell 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.

Separable Crossover-Promoting and Crossover-Constraining Aspects of Zip1 Activity during Budding Yeast Meiosis. [PDF]

open access: yesPLoS Genetics, 2015
Accurate chromosome segregation during meiosis relies on the presence of crossover events distributed among all chromosomes. MutSγ and MutLγ homologs (Msh4/5 and Mlh1/3) facilitate the formation of a prominent group of meiotic crossovers that mature ...

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

open access: yes, 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.

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

open access: yesPLoS 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.

A universal method for automated gene mapping [PDF]

open access: yes, 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 ...

Crossover Interference on Nucleolus Organizing Region-Bearing Chromosomes in Arabidopsis [PDF]

open access: yesGenetics, 2005
Abstract In most eukaryotes, crossovers are not independently distributed along the length of a chromosome. Instead, they appear to avoid close proximity to one another—a phenomenon known as crossover interference. Previously, for three of the five Arabidopsis chromosomes, we measured the strength of interference and suggested a model ...
