  • Title: [Systemic reorganization of the architechtonics of polytene chromosomes in onto- and phylogenesis of malaria mosquitoes. Structural features regional of chromosomal adhesion to the nuclear membrane].
    Author: Stegniĭ VN, Sharakhova MV.
    Journal: Genetika; 1991 May; 27(5):828-35. PubMed ID: 1916252.
    Abstract:
    Principles of organization of chromocenter in salivary gland cells and zones of chromosome attachment to nuclear envelope in ovarian nurse cells were determined. It was shown that blocks of centromeric heterochromatin (alfa-heterochromatin) have no direct connection with nuclear envelope. Such connections are ensured by beta-heterochromatin. Homologous chromosome regions were shown to be of different morphology and nature of chromosome-membrane links in different mosquito species. A map of polytene chromosomes of ovarian nurse cells in Anopheles messeae Fall, was established. No differences were found in band quantity of these chromosomes as compared to salivary gland chromosomes.
