ATR is a multifunctional regulator of male mouse meiosis

Nature Communications, 2018
ATR kinase is required for meiosis in non-mammalian model organisms. Here the authors demonstrate, using a tissue-specific knockout approach, that ATR is also essential for male meiosis in mouse, regulating meiotic recombination and synapsis.

Maximizing meiotic crossover rates reveals the map of Crossover Potential

Nature Communications
Sexual dysmorphism in the number and distribution of meiotic crossovers is seen across species but is poorly understood. Here, we disrupt multiple anti-crossover pathways in hermaphrodite Arabidopsis and analyze thousands of female and male progeny ...

Cytogenomic evaluation of regenerated Aralia elata using PLOP-FISH and flow cytometry

Scientific Reports
Aralia elata is closely related to Panax ginseng and contains high levels of saponins and other medicinal compounds. Successful A. elata micropropagation is commercially significant; however, the genomic stability of tissue culture-derived regenerants is

Magnification of Genes Coding for Ribosomal RNA in Saccharomyces cerevisiae [PDF]

, 1977
When a strain of Saccharomyces cerevisiae monosomic for chromosome I and initially deficient for 25% of the genes coding for ribosomal RNA is repeatedly subcultured, the number of these genes increases to and remains stable at the number in the wild type.

Microscopes and computers combined for analysis of chromosomes [PDF]

, 1969
Scanning machine CHLOE, developed for photographic use, is combined with a digital computer to obtain quantitative and statistically significant data on chromosome shapes, distribution, density, and pairing.

BAF-1–VRK-1 mediated release of meiotic chromosomes from the nuclear periphery is important for genome integrity

Nature Communications
Rapid prophase chromosome movements ensure faithful alignment of the parental homologous chromosomes and successful synapsis formation during meiosis. These movements are driven by cytoplasmic forces transmitted to the nuclear periphery, where chromosome
