In an effort to transfer Botrytis resistance from Oriental lilies to Asiatic hybrids (Lilium, 2n=2x=24) we made a large number of F1 hybrids between these two distantly related species. Because these species belong to two different taxonomic sections, the F1 hybrids were totally sterile and could not be directly used in breeding. Therefore, two approaches were used for utilizing the F1 hybrids....

Interactions between fungi occur when they grow on the same host plant. This is the case of Botrytis cinerea and Penicillium expansum on grape. P. expansum is also responsible for production of the mycotoxin patulin. In this study, the influence of the interaction between both fungi on fungal growth parameters was studied as well as the effect on the accumulation of patulin by P. expansum. For ...

This study demonstrates that the isoprenoid farnesol produces a toxic effect on the phytopathogenic fungus Botrytis cinerea in solid and liquid media. In solid media farnesol retarded 72 h the beginning of mycelial growth. Also, it was demonstrated that the toxic effect is due to farnesol triggers apoptosis in B. cinerea because ROS accumulation, DNA fragmentation and phosphatidylserine externa...

Despite the described central role of jasmonate signaling in plant defense against necrotrophic pathogens, the existence of intraspecific variation in pathogen capacity to activate or evade plant jasmonate-mediated defenses is rarely considered. Experimental infection of jasmonate-deficient and jasmonate-insensitive Arabidopsis thaliana with diverse isolates of the necrotrophic fungal pathogen ...

The gene encoding a XET (xyloglucan endotransglycosylase) from cauliflower ( Brassica oleracea var. botrytis ) florets has been cloned and sequenced. Sequence analysis indicated a high degree of similarity to other XET enzymes belonging to glycosyl hydrolase family 16 (GH16). In addition to the conserved GH16 catalytic sequence motif EIDFE, there exists one potential N-linked glycosylation site...

A virus disease of cabbage (Brassica olerácea Li. var. capitata L.), designated as black ring, is prevalent mainly during the winter and spring seasons near San Pablo and Colma in the San Francisco Bay section and in the Sacramento, Salinas, and Santa Clara Valleys of California (18).^ Other crucifers of more importance ill California, including Brussels sprouts (B. olerácea L. var. gemmijera D...

Arabidopsis VQ motif-containing proteins have recently been demonstrated to interact with several WRKY transcription factors; however, their specific biological functions and the molecular mechanisms underlying their involvement in defense responses remain largely unclear. Here, we showed that two VQ genes, VQ12 and VQ29, were highly responsive to the necrotrophic fungal pathogen Botrytis ciner...

Botrytis cinerea is a ubiquitous filamentous fungal pathogen of a wide range of plant species. The fungus is able to infect all aerial parts of its host plants to a certain extent. Infection may cause enormous damage both during plant growth and in the post-harvest phase (during cold storage or transport). B. cinerea is a major cause of economic loss in the production chain of cut flowers, bulb...
