Phenotypic Variation of Botrytis cinerea Isolates Is Influenced by Spectral Light Quality

Detection of Botrytis cinerea field isolates with multiple fungicide resistance

Genetic characterization of grapevine-infecting Botrytis cinerea isolates from Argentina.

BACKGROUND Botrytis cinerea is an ascomycete with a high genetic diversity and complex population structure, as reported from several hosts and sites. However, nothing is known about its genetic diversity in Argentina. AIMS The aim of this work is to estimate the genetic diversity of a local population of B. cinerea isolates obtained from grapevine in Argentina. METHODS In this work, 35 str...

Oxidation of alcohols by Botrytis cinerea.

Crude cell-free preparations of Botrytis cinerea were found to oxidize straight-chain primary alcohols (except methanol), aromatic primary alcohols, and unsaturated primary alcohols. The resulting products were the corresponding aldehydes and an equal molar quantity of hydrogen peroxide.

Biotransformation of (-)-a-pinene by Botrytis cinerea.

(-)-alpha-Pinene (1), a major constituent of many aromatic plants was biotransformed by the plant pathogenic fungus, Botrytis cinerea to afford three new metabolites, characterized as 3beta-hydroxy-(-)-beta-pinene (10%) (3), 9-hydroxy-(-)-a-pinene (12%) (4), 4beta-hydroxy-(-)-alpha-pinene-6-one (16%) (5) by physical and spectroscopic methods. A known metabolite verbenone (2) was also obtained.

Natural Variation in the VELVET Gene bcvel1 Affects Virulence and Light-Dependent Differentiation in Botrytis cinerea

Botrytis cinerea is an aggressive plant pathogen causing gray mold disease on various plant species. In this study, we identified the genetic origin for significantly differing phenotypes of the two sequenced B. cinerea isolates, B05.10 and T4, with regard to light-dependent differentiation, oxalic acid (OA) formation and virulence. By conducting a map-based cloning approach we identified a sin...
