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 ...

A recurrent translocation is mediated by homologous recombination between HERV-H elements [PDF]
Molecular Cytogenetics, 2012 Background Chromosome rearrangements are caused by many mutational mechanisms; of these, recurrent rearrangements can be particularly informative for teasing apart DNA sequence-specific factors.

Association of homologous chromosomes during floral development [PDF]
Current Biology, 1997 Reduction in chromosome number and genetic recombination during meiosis require the prior association of homologous chromosomes, and this has been assumed to be a central event in meiosis. Various studies have suggested, however, that while the reduction division of meiosis is a universally conserved process, the pre-meiotic association of homologues ...

Homologous chromosome pairing in Schizosaccharomyces pombe [PDF]
Yeast, 2006 AbstractHomologous chromosome pairing is a central feature of meiosis I, contributing to the correct segregation of chromosomes during meiosis. The fission yeast, Schizosaccharomyces pombe, has been widely used to study meiotic chromosome dynamics, partly because studies in this yeast are simplified due to the lack of post‐pairing synaptic structures ...

Modeling homologous chromosome recognition via nonspecific interactions [PDF]
Proceedings of the National Academy of SciencesIn 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.

PAR-TERRA directs homologous sex chromosome pairing [PDF]
Nature Structural & Molecular Biology, 2017 In mammals, homologous chromosomes rarely pair outside meiosis. One exception is the X chromosome, which transiently pairs during X-chromosome inactivation (XCI). How two chromosomes find each other in 3D space is not known. Here, we reveal a required interaction between the X-inactivation center (Xic) and the telomere in mouse embryonic stem (ES ...

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.
