Meiotic recombination: mixing it up in plants
Y Wang, GP Copenhaver - Annual Review of Plant Biology, 2018 - annualreviews.org

Chromosome-level assembly of Arabidopsis thaliana Ler reveals the extent of translocation and inversion polymorphisms
Resequencing or reference-based assemblies reveal large parts of the small-scale
sequence variation. However, they typically fail to separate such local variation into colinear …

Epigenetic activation of meiotic recombination near Arabidopsis thaliana centromeres via loss of H3K9me2 and non-CG DNA methylation
Eukaryotic centromeres contain the kinetochore, which connects chromosomes to the
spindle allowing segregation. During meiosis, centromeres are suppressed for inter …
