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.

Cas9/Nickase-induced allelic conversion by homologous chromosome-templated repair in Drosophila somatic cells. [PDF]

Sci Adv, 2022
Repair of double-strand breaks (DSBs) in somatic cells is primarily accomplished by error-prone nonhomologous end joining and less frequently by precise homology-directed repair preferentially using the sister chromatid as a template.

CRISPR-induced double-strand breaks trigger recombination between homologous chromosome arms. [PDF]

Life Sci Alliance, 2019
CRISPR–Cas9 enables recombination between homologous chromosome arms at predefined sites and also underscores the need for caution when applying CRISPR technologies in translational medicine.

Meiotic cohesin-based chromosome structure is essential for homologous chromosome pairing in Schizosaccharomyces pombe. [PDF]

Chromosoma, 2016
Chromosome structure is dramatically altered upon entering meiosis to establish chromosomal architectures necessary for the successful progression of meiosis-specific events. An early meiotic event involves the replacement of the non-SMC mitotic cohesins

Clubroot resistance gene Rcr6 in Brassica nigra resides in a genomic region homologous to chromosome A08 in B. rapa

BMC Plant Biology, 2019
Background Clubroot, caused by Plasmodiophora brassicae Woronin, is a very important disease of Brassica species. Management of clubroot relies heavily on genetic resistance.

Nuclear reorganization and homologous chromosome pairing during meiotic prophase require C. elegans chk-2. [PDF]

Genes & Development, 2001
Analysis of mutants defective in meiotic chromosome pairing has uncovered a role for Caenorhabditis elegans chk-2 in initial establishment of pairing between homologous chromosomes during early meiotic prophase.

Maintenance DNA methylation in pre-meiotic germ cells regulates meiotic prophase by facilitating homologous chromosome pairing.

Development, 2021
Heterochromatin-related epigenetic mechanisms, such as DNA methylation, facilitate pairing of homologous chromosomes during the meiotic prophase of mammalian spermatogenesis.

Telomeres and Subtelomeres Dynamics in the Context of Early Chromosome Interactions During Meiosis and Their Implications in Plant Breeding

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.
