Molecular characteristics of the heterochromatic I elements from a reactive strain of Drosophila melanogaster.

Journal of molecular evolution - 1 Nov 1990

Vaury C, Abad P, Pelisson A, Lenoir A, Bucheton A

Abstract excerpt

There are two categories of strains in Drosophila melanogaster with respect to the I-R system of hybrid dysgenesis. The inducer strains contain particular transposable elements named I factors. They are not present in the strains of the other category called reactive (R) strains. Defective I elements are present in the pericentromeric regions of both categories of strains. This last subfamily of I sequences has...
