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.

[Synaptonemal complexes in vaccinated mice].
TSitologiia i genetika, 1991Synaptonemal complexes of spermatocytes I obtained from C57BL/6j male mice treated with inactivated bacterial vaccines were spread over the hypotonic phase and then were investigated using light microscope. The slides of synaptonemal complexes of mice treated with cyclophosphamide were used as positive control.
