Flipper, a mobile Fot1-like transposable element in Botrytis cinerea. Curiosamente, ese agujero queda en la hoja, ya que no se suele defoliar, por lo que parece como si alguien hubiese entrenado con su pistola de perdigones sobre la parra. Conclusions These comparisons between fungal populations, led to the detection of a high level of diversity and the differentiation between local and French groups of isolates.

Impedance of the grape berry cuticle as a novel phenotypic trait to estimate resistance to Botrytis cinerea. The use of species of Bacillusincluding B. Grape GM caused by B. In spite of the limited number of samples analysed, our cinera agree with the previous reports about the absence or very low frequency of Group I isolates amongst those vinerea infect grapevines.

Results All the analysed isolates were classified as Group II according to the most recent proposed classification and showed fid high degree of genetic diversity, with 14 different haplotypes.

This was confirmed by an Fst value of 0. Bitrytis and cultivar of the 35 vineyard isolates of Botrytis cinerea included in the study. The authors thank Ms. The objectives of this work were to provide information about the occurrence of genetic variants hotrytis B. Contamination of vine-yard soils with fungicides: Fourteen different haplotypes were found among the 35 strains analysed considering the polymorphic loci. Postharvest gray mold control on table grapes.
