Sclerotinia trifoliorum is an important pathogen of forage legumes and some grain legumes. Attempts to study its population biology using microsatellite markers developed for Sclerotinia sclerotiorum and Sclerotinia subarctica resulted in no amplification or low levels of polymorphism. This study reports the development and characterization of 33 microsatellite loci developed from a microsatell...

As culturas anuais geralmente são acometidas por doenças causadas fitopatógenos do solo, que prejudicam a produção agrícola gerando perdas econômicas. Entre os mais comuns estão Sclerotinia sclerotiorum, Fusarium sp. e Macrophomina phaseolina. Embora o efeito benéfico de espécies adubação verde em rotação cultura já seja conhecido na proteção fertilidade ainda limitadas as informações proporcio...

Sclerotinia stem rot caused by Sclerotinia sclerotiorum is one of the most devastating diseases in many important crops including Brassica napus worldwide. Quantitative resistance is the only source for genetic improvement of Sclerotinia-resistance in B. napus, but the molecular basis for such a resistance is largely unknown. Here, we performed dynamic transcriptomic analyses to understand the ...

A fungal isolate collected from infected paprika (Capsicum annuum var. grossum) was characterized as Sclerotinia sclerotiorum based on its ability of sclerotium formation, physiological and molecular properties. When the isolate was grown on potato dextrose agar, oatmeal agar, and malt extract agar, it grew most well on PDA. Optimal temperature and pH for its growth were 25℃ and pH 7, respectiv...

Sclerotinia rot caused by Sclerotinia sclerotiorum is one of the most serious diseases of oilseed rape. To understand the resistance mechanisms in the Brassica napus to S. sclerotiorum, comparative disease progression, histological and proteomic studies were conducted of two B. napus genotypes (resistant cv. Charlton, susceptible cv. RQ001-02M2). At 72 and 96 h post inoculation (hpi), lesion si...

Solvent extracts of Sclerotinia sclerotiorum sclerotia were nontoxic to mice and chicken embryos; psoralens were not detected. Solvent extracts of soybeans inoculated with 10 strains of S. sclerotiorum were toxic on injection but nontoxic on per os administration to mice. The presence of chlorinated hydrocarbons in the soybeans may partially help explain toxicity by intraperitineal injection.
