Abstract

Molecular markers revealed that Botryotinia fuckeliana (the teleomorph of Botrytis cinerea), a haploid, filamentous, heterothallic ascomycete, contained a large amount of intrapopulation genetic variation. Themarkers were used to determine the mode of reproduction and the population structure of this fungus. We did not detect any differentiation between isolates from different organs, collection dates, varieties ofgrape, or locations in the Champagne region of France, but two unexpected sympatric populations were identified. One group of isolates (transposa) contained the transposable elements Boty and Flipper; the other (vacuma) did not. These groups differed from one another for all theother markers. RFLP markers showed that there was genetic recombination in both groups of isolates. We conclude that there are two sympatric populations of B. fuckeliana in Champagne. One species (transposa) seems to be local and well adapted, while the other one (vacuma) is presumably a heterogeneous migrant population.
