Cutinase of Botrytis cinerea has been suggested to play an important role in penetration of host tissues. A protein fraction with cutin hydrolyzing activity was purified from culture filtrates of B. cinerea induced for cutinase activity. An 18-kDa protein in this fraction was identified as cutinase and the corresponding gene cutA was cloned. The gene is present in a single copy in the genome of...

The Saccharomyces cerevisiae Elongator complex consisting of the six Elp1-Elp6 proteins has been proposed to participate in three distinct cellular processes: transcriptional elongation, polarized exocytosis and formation of modified wobble uridines in tRNA. In this study, we investigated the function of BcElp4 in Botrytis cinerea, which is homologous to S. cerevisiae Elp4. A bcelp4 deletion mu...

Bis(2,3-dibromo-4,5-dihydroxybenzyl) ether (BDDE) is a bromophenol isolated from marine algae. Previous reports have shown that BDDE possesses cytotoxic and antibacterial activity. In the present study, we demonstrate that BDDE displays broad-spectrum antifungal activities, especially on Botrytis cinerea. BDDE inhibits the growth of B. cinerea cultured on a solid medium of potato dextrose agar ...

The epiphytic bacterium Rahnella aquatilis, isolated from fruit and leaves of apples, was tested for antagonistic properties against Penicillium expansum and Botrytis cinerea on Red Delicious apple fruit. In "in vitro" assays, this bacterium inhibited completely the germination of P. expansum and B. cinerea spores, but it needed direct contact with the spores to do it. However the putative mech...

Botrytis cinerea Pers., the causal agent of gray mold, infects more than 200 plant species. This pathogen has traditionally been controlled by fungicides. However, with the increasing demand for pesticide-free foods new control strategies are needed. The objective of this study was to isolate and select grapevine (Vitis vinifera L.) epiphytic yeasts for the biocontrol of B. cinerea in table gra...
