Control of meiotic crossing over in plant breeding. [PDF]
Vavilovskii Zhurnal Genet Selektsii, 2023 Meiotic crossing over is the main mechanism for constructing a new allelic composition of individual chromosomes and is necessary for the proper distribution of homologous chromosomes between gametes.

DNA polymerase theta suppresses mitotic crossing over. [PDF]
PLoS Genet, 2021 Polymerase theta-mediated end joining (TMEJ) is a chromosome break repair pathway that is able to rescue the lethality associated with the loss of proteins involved in early steps in homologous recombination (e.g., BRCA1/2). This is due to the ability of

Positive Selection and Functional Divergence at Meiosis Genes That Mediate Crossing Over Across the Drosophila Phylogeny. [PDF]
G3 (Bethesda), 2019 Meiotic crossing over ensures proper segregation of homologous chromosomes and generates genotypic diversity. Despite these functions, little is known about the genetic factors and population genetic forces involved in the evolution of recombination rate

Sex without crossing over in the yeast Saccharomycodes ludwigii. [PDF]
Genome Biol, 2021 Background Intermixing of genomes through meiotic reassortment and recombination of homologous chromosomes is a unifying theme of sexual reproduction in eukaryotic organisms and is considered crucial for their adaptive evolution.

Human Cell Assays for Synthesis-Dependent Strand Annealing and Crossing over During Double-Strand Break Repair. [PDF]
G3 (Bethesda), 2017 DNA double-strand breaks (DSBs) are one of the most deleterious types of lesions to the genome. Synthesis-dependent strand annealing (SDSA) is thought to be a major pathway of DSB repair, but direct tests of this model have only been conducted in budding

Crossing over...Markov meets Mendel. [PDF]
PLoS Comput Biol, 2012 Chromosomal crossover is a biological mechanism to combine parental traits. It is perhaps the first mechanism ever taught in any introductory biology class.

Contribution of crossing over to genetic variance in maize and wheat populations. [PDF]
Plant GenomeCrossing over breaks linkages and leads to a wider array of allele combinations. My objective was to assess the contribution of crossing over to genetic variance (VG) in maize (Zea mays L.) and wheat (Triticum aestivum L.).

A BIRD´S-EYE VIEW OF CHROMOSOMES DURING MEIOTIC PROPHASE I [PDF]
BAG. Journal of Basic and Applied Genetics, 2022 The present review aims to summarize the research carried out in relation to meiosis in birds, especially by observing the protein axes of the chromosomes in prophase I of meiosis. This line of research, initially developed in Argentina, has provided key

SUMO is a pervasive regulator of meiosis
eLife, 2021 Protein modification by SUMO helps orchestrate the elaborate events of meiosis to faithfully produce haploid gametes. To date, only a handful of meiotic SUMO targets have been identified.
