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...

UNLABELLED Members of the family Partitiviridae have bisegmented double-stranded RNA (dsRNA) genomes and are not generally known to cause obvious symptoms in their natural hosts. An unusual partitivirus, Sclerotinia sclerotiorum partitivirus 1 (SsPV1/WF-1), conferred hypovirulence on its natural plant-pathogenic fungal host, Sclerotinia sclerotiorum strain WF-1. Cellular organelles, including m...

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.

Bacillus amyloliquefaciens strain NJZJSB3 has shown antagonism of several phytopathogens in vitro, especially Sclerotinia sclerotiorum. Both the broth culture and cell suspension of strain NJZJSB3 could completely protect the detached leaves of canola (Brassica napus) from S. sclerotiorum infection. In pot experiments, the application of strain NJZJSB3 cell suspension (10(8) CFU/ml) decreased t...

Solgi T., Moradyar M., Zamani M.R., Motallebi M. (2015): Transformation of canola by chit33 gene towards improving resistance to Sclerotinia sclerotiorum. Plant Protect. Sci., 51: 6–12. An endochitinase gene (chit33-cDNA) from the biocontrol fungus Trichoderma atroviride was overexpressed under the CaMV35S constitutive promoter in canola (R line Hyola 308). Transformation of cotyledonary petiol...

White mold of cabbage caused by Sclerotinia sclerotiorum was identified in Bangladesh Agricultural Research Institute (BARI), Bangladesh. The fungus isolated from the symptomatic leaves on potato dextrose agar (PDA) medium. Subsequent inoculation S. detached and heads confirmed pathogenicity fungus. Based morphological characteristics phylogenetic analysis, pathogen as sclerotiorum.
