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 ...

Meiotic telomeres: a matchmaker for homologous chromosomes [PDF]

Genes to Cells, 1998
Telomeres, with their special structures and special schemes of synthesis, are essential for protecting the ends of eukaryotic linear chromosomes during cell proliferation. In addition to this basic function, the meiosis‐specific functions of telomeres have long been inferred from the cytological observations of characteristic chromosome configurations

Recruitment and rejoining of remote double-strand DNA breaks for enhanced and precise chromosome editing [PDF]

Genome Biology
Chromosomal rearrangements, such as translocations, deletions, and inversions, underlie numerous genetic diseases and cancers, yet precise engineering of these rearrangements remains challenging.

Independent evolution of satellite DNA sequences in homologous sex chromosomes of Neotropical armored catfish (Harttia) [PDF]

Communications Biology
The Neotropical armored catfish Harttia is a valuable model for studying sex chromosome evolution, featuring two independently evolved male-heterogametic systems.

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 ...

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.
