Synaptonemal complex karyotype of Eimeria tenella
International Journal for Parasitology, 2005In most organisms, biological variability rests on the behaviour of the chromosomes in the meiotic context. Despite the importance of meiosis, very little is known about the meiotic behaviour of the Eimeria chromosomes. The aim of the present study is to describe the standard synaptonemal complex karyotype from Eimeria tenella oocyst spreads by ...

Spreading the synaptonemal complex of Neurospora crassa
Chromosoma, 1993A protocol was developed to spread the synaptonemal complex (SC) of the fungus Neurospora crassa. It involves direct mechanical breakage of meiotic cells before spreading. This technique makes it possible to examine the SC of the same nucleus with both light and electron microscopy. This protocol is potentially applicable for other Pyrenomycetes.

The synaptonemal complex — the chaperone of crossing over
Chromosome Research, 1996During meiosis homologous chromosomes pair and exchange homologous chromosome segments. The synaptonemal complex (SC) forms between paired chromosomes. The role of the SC in the process of reciprocal exchange of flanking markers is a matter of debate. I propose a dual pathway for reciprocal exchange of flanking markers (REFM).

Heterochromatin, the synaptonemal complex and crossing over
Journal of Cell Science, 1984ABSTRACT A combined light- and electron-microscopic examination of chromosomes from two angiospermous plants, Plantago ovata and Lycopersicon esculentum, and a mammal, Mus musculus, was performed. From this investigation three observations have been made that may be relevant to the observed lack of crossing over in heterochromatin.

Synaptonemal complexes in the ovaries ofGalleria mellonella
Experientia, 1972Dans les oocytes deGalleria mellonella, on a trouve des complexes synaptonemaux, indiquant la presence de crossing-over dans cet organisme. Le complex synaptonemal s'est montre aussi dans un trophocyte, mais il semble etre ici un phenomene accidentel.
