  • Title: Heterochromatin diversity and cyclic responses to selective silver staining in Aedes aegypti (L.).
    Author: Wallace AJ, Newton ME.
    Journal: Chromosoma; 1987; 95(1):89-93. PubMed ID: 2438099.
    Abstract:
    In interphase cells of Aedes aegypti (L.) (2n = 4+ XX/XY), only the nucleolus responded to selective silver staining. The secondary constriction on chromosome 3 remained unresponsive at all times but the six centromeres were identified throughout mitosis from early prophase as well as those stages of meiosis subsequent to diplotene. The centromeric blocks were not synonymous with the pericentric heterochromatin revealed by C-banding. X chromosomes without an intercalary C-band were newly discovered in Ae. aegypti in the Bangalore strain. Sequential Q- or Hoechst 33258/C-banding in this and the Trinidad-30 strain revealed intercalary heterochromatin diversity within and between strains and also differences between intercalary and pericentric heterochromatin.
