Synaptonemal complexes: structure and function
Current Opinion in Cell Biology, 1996Synaptonemal complexes (SCs) are zipper-like structures which are assembled between homologous chromosomes during the prophase of the first meiotic division. Their assembly and disassembly correlate with the successive chromatin rearrangements of meiotic prophase, namely the condensation, pairing, recombination and disjunction of homologous chromosomes.

Superresolution imaging of the synaptonemal complex
2018This chapter describes how two different superresolution microscopy techniques, namely, structured illumination microscopy and direct stochastic optical reconstruction microscopy, can be used to analyze the molecular architecture of the synaptonemal complex.

Synaptonemal complexes in insects
International Journal of Insect Morphology and Embryology, 1996Abstract The synaptonemal complex (SC) is the key nuclear element formed in meiotic prophase I to join 2 homologous chromosomes at the pachytene bivalent. It is a highly conserved structure that is universally present in eukaryotes. The SC is presented as a tripartite protein structure, which consists of 2 lateral elements and a central region.

Synaptonemal complexes in a tetraploid mouse spermatocyte
Experimental Cell Research, 1977Summary Quadrivalents, represented by unique synaptonemal complex configurations, together with normal bivalents are observed for the first time in a mammalian tetraploid pachytene spermatocyte prepared by microspreading. The chromosomal axes (lateral elements) clearly demonstrate the switching of partners in the quadrivalents as predicted from ...

Synaptonemal complex karyotyping in Melanoplus Differentialis
Journal of Cell Science, 1977ABSTRACT The chromosomal axes of the spermatocytes of the grasshopper Melanoplus differentiate have been studied with a modification of the microspreading procedure used previously. The whole complement of synaptonemal complexes (SCs) and the axis of the X chromosome have been described and measured.

A new synaptic anomaly: irregular synaptonemal complexes
Human Genetics, 1986In this paper we describe a new synaptic anomaly characterized by the presence of irregular synaptonemal complexes (SCs) in two sterile patients.

The synaptonemal complex—50 years
Chromosoma, 20062006 is a memorable year for meiosis research as it is the 50th anniversary of the discovery of synaptonemal complexes (SCs). To mark this occasion, Chromosoma has decided to publish a special issue entirely devoted to this meiotic structure and I have gladly accepted the editorial responsibility for organizing this issue. I hope that we have succeeded

Is the Synaptonemal Complex a Disjunction Machine?
Journal of Heredity, 1995The chiasma has been recognized as a major feature of meiosis both visually and functionally for > 85 years. But its functional basis remains poorly understood. In interaction with the spindle, it generally mediates the ultimate distribution of homologues to opposite poles at meiosis I to yield correct disjunction.

The synaptonemal complex and the achiasmatic condition
Journal of Cell Science, 1973ABSTRACT The onion species AUium amplectans includes both a triploid and a tetraploid variety. By light microscopy both varieties appear to have normal synapsis during pachytene of meiosis. However, the triploid does not form chiasmata and exhibits almost total asynapsis following pachytene.
