Meiotic recombination: mixing it up in plants
Y Wang, GP Copenhaver - Annual Review of Plant Biology, 2018 - annualreviews.org
Meiosis halves diploid chromosome numbers to haploid levels that are essential for sexual
reproduction in most eukaryotes. Meiotic recombination ensures the formation of bivalents …

Learning to tango with four (or more): the molecular basis of adaptation to polyploid meiosis
K Bomblies - Plant reproduction, 2023 - Springer
Polyploidy, which arises from genome duplication, has occurred throughout the history of
eukaryotes, though it is especially common in plants. The resulting increased size …

Nucleosomes and DNA methylation shape meiotic DSB frequency in Arabidopsis thaliana transposons and gene regulatory regions
Meiotic recombination initiates from DNA double-strand breaks (DSBs) generated by SPO11
topoisomerase-like complexes. Meiotic DSB frequency varies extensively along eukaryotic …

FANCM promotes class I interfering crossovers and suppresses class II non-interfering crossovers in wheat meiosis
FANCM suppresses crossovers in plants by unwinding recombination intermediates. In
wheat, crossovers are skewed toward the chromosome ends, thus limiting generation of …

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 …

Unleashing meiotic crossovers in hybrid plants
JB Fernandes, M Séguéla-Arnaud… - Proceedings of the …, 2018 - National Acad Sciences
Meiotic crossovers shuffle parental genetic information, providing novel combinations of
alleles on which natural or artificial selection can act. However, crossover events are …

Natural variation and dosage of the HEI10 meiotic E3 ligase control Arabidopsis crossover recombination
During meiosis, homologous chromosomes undergo crossover recombination, which
creates genetic diversity and balances homolog segregation. Despite these critical …
