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.

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.

Role of chromosome ends in meiotic stability, recombination and wheat evolution in the context of breeding [PDF]
BMC Plant BiologyWheat is one of the most important crops worldwide, and understanding its genome organisation is crucial for geneticists and breeders. In this study, we examined the dynamic roles of telomeric and subtelomeric regions in wheat, focusing on their ...

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.

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.

Formation of the synaptonemal complex in a gynogenetic allodiploid hybrid fish
Frontiers in Genetics, 2023 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.
