Evolution of natural populations in the Drosophila melanogaster sigma virus system I. Languedoc (southern France).

Genetica - 1 Jan 1990

Fleuriet A, Periquet G, Anxolabéhère D

Abstract excerpt

In natural populations of Drosophila melanogaster, sigma virus is usually present in a minority of individuals. The virus is transmitted transovarially but is not contagious from fly to fly. Two viral Types (I and II) are found in populations. One of them (Type II) is better adapted to an allele for resistance to the virus, present as a polymorphism in fly populations. Previous observations have led to the...
