    Dipartimento di Biologia Animale, Universita di Palermo, Palermo, Italy
    Genes Genet Syst 78:427-32. 2003
    ..This suggests that heterochromatic DNA of P. b. punctatum is peculiar as compared with other types of heterochromatin studied so far in other invertebrate taxa. By rDNA FISH major ribosomal genes were mapped on the X chromosome...

    Genetica 110:151-5. 2000
    ..Our results indicate that RNA genes are throughout heterochromatin in eight chromosomes involving 1/4 of the total heterochromatin which, in this species, is about 67% of the total DNA. Ag-NOR and FISH patterns were not coincident...
