FIGNL1 Inhibits Non-homologous Chromosome Association and Crossover Formation [PDF]
Frontiers in Plant Science, 2022 Meiotic crossovers (COs) not only generate genetic diversity but also ensure the accuracy of homologous chromosome segregation. Here, we identified FIGNL1 as a new inhibitor for extra crossover formation in rice.

Competition for Chiasma Formation Between Identical and Homologous (But Not Identical) Chromosomes in Synthetic Autotetraploids of Arabidopsis thaliana [PDF]
Frontiers in Plant Science, 2019 Polyploid organisms provide additional opportunities to study meiosis in a more complex context since more than two potential homologous chromosomes are available.

Chromosome architecture and homologous recombination in meiosis
Frontiers in Cell and Developmental Biology, 2023 Meiocytes organize higher-order chromosome structures comprising arrays of chromatin loops organized at their bases by linear axes. As meiotic prophase progresses, the axes of homologous chromosomes align and synapse along their lengths to form ladder ...

Modeling homologous chromosome recognition via nonspecific interactions. [PDF]
Proc Natl Acad Sci U S AIn many organisms, most notably Drosophila , homologous chromosomes associate in somatic cells, a phenomenon known as somatic pairing, which takes place without double strand breaks or strand invasion, thus requiring some other mechanism for homologs to recognize each other.

Chromosome ends initiate homologous chromosome pairing during rice meiosis [PDF]
Plant PhysiologyAbstract During meiotic prophase I, chromosomes undergo large-scale dynamics to allow homologous chromosome pairing, prior to which chromosome ends attach to the inner nuclear envelope and form a chromosomal bouquet. Chromosome pairing is crucial for homologous recombination and accurate chromosome segregation during meiosis.

Site-Specific Sequence Exchange Between Homologous and Non-homologous Chromosomes [PDF]
Frontiers in Plant Science, 2022 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 transgenes into a previously created transgenic locus.

Frontiers in Plant Science, 2021 Genomic architecture facilitates chromosome recognition, pairing, and recombination. Telomeres and subtelomeres play an important role at the beginning of meiosis in specific chromosome recognition and pairing, which are critical processes that allow ...

Haploidy of somatic cells in mouse oocyte using somatic cell nuclear transfer
Journal of Animal Reproduction and Biotechnology, 2022 Haploidization in somatic cells is the process of reducing the diploid somatic chromosomes to haploid. Several studies have attempted somatic haploidization using oocytes in mice and humans.
