DOI: 10.1007/s00294-020-01077-9
Abstract: Pairing of homologous chromosomes is crucial for ensuring accurate segregation of chromosomes during meiosis. Molecular mechanisms of homologous chromosome pairing in meiosis have been extensively studied in the fission yeast Schizosaccharomyces pombe . In this… read more here.

DOI: 10.1016/j.ceb.2018.01.005
Abstract: Meiosis is a key processes of sexual reproduction in eukaryotes. By combining two cell division cycles with a single round of DNA replication meiosis provides a mechanism to generate haploid gametes. Coincidentally, processes involved in… read more here.

DOI: 10.1038/s41586-020-2248-2
Abstract: In most species, homologous chromosomes must recombine in order to segregate accurately during meiosis 1 . Because small chromosomes would be at risk of missegregation if recombination were randomly distributed, the double-strand breaks (DSBs) that… read more here.

DOI: 10.1371/journal.pgen.1007854
Abstract: Meiosis is a specialized cell-division process in germ cells that ensures proper segregation of a single haploid genome into each gamete from a diploid precursor cell. This process ensures that the embryo receives the correct… read more here.

DOI: 10.3389/fgene.2023.998775
Abstract: Introduction: The correct pairing and separation of homologous chromosomes during meiosis is crucial to ensure both genetic stability and genetic diversity within species. In allodiploid organisms, synapsis often fails, leading to sterility. However, a gynogenetic… read more here.

DOI: 10.3389/fpls.2018.01924
Abstract: Polyploid organisms provide additional opportunities to study meiosis in a more complex context since more than two potential homologous chromosomes are available. When the chromosome complement of a diploid individual is duplicated, each chromosome is… read more here.

DOI: 10.3389/fpls.2022.828960
Abstract: Transgene integration typically takes place in an easy-to-transform laboratory variety before the transformation event is introgressed through backcrosses to elite cultivars. As new traits are added to existing transgenic lines, site-specific integration can stack new… read more here.

Meiotic Chromosome Contacts as a Plausible Prelude for Robertsonian Translocations
Sign Up to like & getrecommendations! Published in 2020 at "Genes"
DOI: 10.3390/genes11040386
Abstract: Robertsonian translocations are common chromosomal alterations. Chromosome variability affects human health and natural evolution. Despite the significance of such mutations, no mechanisms explaining the emergence of such translocations have yet been demonstrated. Several models have… read more here.
