Faithful chromosome segregation in meiosis is essential for ploidy stability over sexual life cycles. In plants, defective chromosome segregation caused by gene mutations or other factors leads to the formation of unbalanced or unreduced gametes creating aneuploid or polyploid progeny, respectively. ...

This review focuses on the four fundamental differences between mitotic and meiotic chromosome segregation that allow the ordered reduction of chromosome number in meiosis: (1) reciprocal recombination and formation of chiasmata between homologous chromosomes, (2) suppression of sister kinetochore bi...

Accurate chromosome segregation during meiosis is crucial for reproduction. Human and porcine oocytes transiently cluster their chromosomes before the onset of spindle assembly and subsequent chromosome segregation. The mechanism and function of chromoso
Kinetochore recruitment of two nucleolar proteins is required for homolog segregation in meiosis I. Halving of the chromosome number during meiosis I depends on the segregation of maternal and paternal centromeres. This process relies on the attachment of...

Interestingly, in Xenopus laevis embryonic extracts, Ran-GTP is required for spindle assembly at the 4-cell stage, but not at the ~4000 cell stage3. However, it remains unclear how Ran-GTP promotes spindle assembly and chromosome segregation in live Xenopus embryos and in other species. In ...
