Failure of homologous synapsis and sex-specific reproduction problems [PDF]
The prophase of meiosis I ensures the correct segregation of chromosomes to each daughter cell. This includes the pairing, synapsis and recombination of homologous chromosomes. A subset of chromosomal abnormalities, including translocation and inversion,

Accumulation of ph1 (zip4-5B) and ph2 (msh7-3D) mutations fails to boost homoeologous recombination in hexaploid wheat [PDF]
Diversification of the hexaploid (bread) wheat genetic pool using wild genetic resources relies on effective meiotic recombination (crossover) between wheat chromosomes and their counterparts from related species (homoeologues).

Somatic Kitl promotes mTOR to facilitate prophase I of meiosis in female embryonic gonads [PDF]
Homologous synapsis and recombination are the central events that take place in the prophase I of meiosis. Signaling that promotes the germ cell differentiation and prophase I remains elusive.

The essential elements for the noncovalent association of two DNA ends during NHEJ synapsis
During a process termed synapsis, the two DNA ends at a double-strand break (DSB) are brought together into physical proximity. Here, the authors use a single-molecule FRET approach with purified proteins to investigate the mechanism of synapsis in DSB ...

Speedy A governs non-homologous XY chromosome desynapsis as a unique prerequisite for XY loop-axis organization [PDF]
In mouse early pachytene spermatocytes, the X and Y chromosomes undergo rapid non-homologous (NH) synapsis and desynapsis, but the functional significance remains unknown.

Chromosome segregation in plant meiosis [PDF]
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

The C. elegans DSB-2 protein reveals a regulatory network that controls competence for meiotic DSB formation and promotes crossover assurance. [PDF]
For most organisms, chromosome segregation during meiosis relies on deliberate induction of DNA double-strand breaks (DSBs) and repair of a subset of these DSBs as inter-homolog crossovers (COs).
