TL;DR: It is shown that the synaptonemal complex, a structure that zips homologous chromosomes together during meiosis, is essential for crossover interference in Arabidopsis, and genome-wide analysis of recombination revealed that CO interference is abolished, with the frequent observation of close COs.

TL;DR: A protocol to preserve the 3D configuration of A. thaliana meiocytes and reveal differential localization behaviors of chromosome ends is set up, showing that the number of telomeres in a bouquet and its volume vary greatly, thus revealing the complexity ofTelomere behavior during meiotic prophase I.

TL;DR: In this article, the authors show that MTOPVIB and PRD1 provide the link between the catalytic sub-complex and the other DSB proteins, while PRD3/AtMER2, while localized to the axis, does not assemble a canonical pre-DSB complex but establishes a direct link between DSB-forming and resection machineries.

TL;DR: This study produced 897 A. thaliana homozygous mutant lines using Ethyl Methyl Sulfonate mutagenesis followed by either single seed descent or haploid doubling, showing the potential of this mutant population for screening for any qualitative or quantitative phenotype.

TL;DR: Considering the meiotic abnormalities observed and the probability of aneuploidy in the F2 plants, the C. microcarpa accessions used in this study would be difficult to use as sources of genetic variability for the crop.
