ABSTRACT
BACKGROUND:
The centrosome is the main center of the organization of microtubules (MT) in the cell, the origin for the formation of flagella and cilia, as well as the site of many regulatory intracellular processes. In diploid cells, the centrosome includes two centrioles connected to some additional structures and surrounded by pericentriolar material.METHODS:
The ultrastructure of the cells was studied using transmission electron microscopy on serial ultrathin sections.RESULTS:
Here, using transmission electron microscopy on a complete series of ultrathin sections of the centrosome region, we studied the relation between the number of centrioles and ploidy in diploid cells of female wasps and haploid cells of male in the parasitoid wasp Anisopteromalus calandrae (Hymenoptera). It showed that the haploid cells of the male insect have the same number of centrioles as the diploid cells of the female.CONCLUSIONS:
It can be concluded that there is no strict correlation between the number of chromosome sets (ploidy) and the number of centrioles in haplodiploid insects.Key words
