Plant diseases are caused by pathogen populations continuously subjected to evolutionary forces (genetic flow, selection, and recombination). Ascochyta blight, caused by Mycosphaerella pinodes, is one of the most damaging necrotrophic pathogens of field peas worldwide. In France, both winter and spring peas are cultivated. Although these crops overlap by about 4 months (March to June), primary ...
Chemotaxonomy and the comparative analysis of metabolic features of fungi have the potential to provide valuable information relating to ecology and evolution, but have not been fully explored in fungal biology. Here, we investigated the chemical diversity of legume-associated Ascochyta and Phoma species and the possible use of a metabolomics approach using liquid chromatography-mass spectromet...
Root rot is an important and widespread disease that often causes significant reduction in the yield and quality of harvested peas throughout the production areas in New York. Pea root rot can be caused by one of several soilborne pathogens or various combinations of root pathogens and also non-pathogens. In recent years, Fusarium solani f. sp. pisi (causal pathogen of Fusarium root rot) has be...
A new antibiotic, ascochlorin, C23H29O4CI, was obtained from the filter cake of the fermented broth of Ascochyta viciae Libert. Ascochlorin inhibits plaque formation of both DNA and RNA viruses in the agar-diffusion plaque inhibition method. However, it showed no antiviral activity by the tube culture method. It showed cytotoxicity to chick embryo fibroblast monolayer and HeLa cells at a concen...
