[Systemic reorganization of the architectonics of polytene chromosomes in the onto- and phylogenesis of malaria mosquitoes].

Cardinal differences in the spatial organization of polytene chromosomes in the nuclei of salivary gland cells (malphigian tubules) and nurse ovarian cells in malarial mosquitoes of Anopheles maculipennis complex are found. The chromosomes have typical chromocentric organization in salivary gland cells and malphigian tubules. In contrast to these cells, the trophocytes have no single chromocentre and some of their chromosomes are rigidly attached to the nucleus envelope with the centromeric parts or with the particular loci. The loci-specificity of the X-chromosome intercalary parts' attachment to the nucleus envelope is found in Anopheles messeae.
