DNA end configurations dictate synaptic complex formation during NHEJ-mediated end bridging [PDF]
Nature CommunicationsSynapsis, the physical bridging of two broken DNA ends, is a critical step in non-homologous DNA end joining (NHEJ), the primary pathway for repairing DNA double-strand breaks (DSBs) in vertebrates.

Failure of homologous synapsis and sex-specific reproduction problems [PDF]
Frontiers in Genetics, 2012 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,

Chromosome segregation in plant meiosis [PDF]
Frontiers in Plant Science, 2014 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

Accumulation of ph1 (zip4-5B) and ph2 (msh7-3D) mutations fails to boost homoeologous recombination in hexaploid wheat [PDF]
Frontiers in Plant ScienceDiversification 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]
Cell Death and DiseaseHomologous 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.

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

Synapsis promoted by ustilago rec1 protein
Cell, 1984 Ustilago rec 1 protein pairs homologous DNA molecules by promoting both synapsis and strand transfer. Complexes formed with rec 1 protein and a homologous combination of single-stranded and duplex DNA that appear to be synaptic structures can be detected by use of a nitrocellulose filter assay.

The Ecm11-Gmc2 complex promotes synaptonemal complex formation through assembly of transverse filaments in budding yeast [PDF]
, 2013 During meiosis, homologous chromosomes pair at close proximity to form the synaptonemal complex (SC). This association is mediated by transverse filament proteins that hold the axes of homologous chromosomes together along their entire length. Transverse
