Sclerotinia sclerotiorum (Lib.) de Bary is a broad range fungal pathogen which attacks more than 500 species of higher plants (Boland and Hall, 1994; Saharan and Mehta, 2008; Sharma et al.,, 2015a). The pathogen can cause serious losses in yield and quality on numerous important field and vegetable crops (Purdy, 1979). Stem rot of Indian mustard caused by S. sclerotiorum (Lib.) de Bary has beco...

White mold is an agricultural disease caused by the fungus Sclerotinia sclerotiorum, which affects important crops. There are different ways of controlling this organism, but none provides inhibition of its resistance structures (sclerotia). Nanotechnology offers promising applications in agricultural area. Here, silver nanoparticles were biogenically synthesized using the fungus Trichoderma ha...

This study aimed to evaluate the inhibitory effects of dill (Anethum graveolens L.) seed essential oil against Sclerotinia sclerotiorum and its mechanism of action. The antifungal activities of the two main constituents, namely carvone and limonene, were also measured. Mycelial growth and sclerotial germination were thoroughly inhibited by dill seed essential oil at the 1.00 μL/mL under contact...

Sclerotinia sclerotiorum is a devastating plant pathogen that causes substantial losses in various agricultural crops. Although plants have developed some well-known defense mechanisms against invasive fungi, much remains to be learned about responses fungal pathogens. In this study, we investigated how S. infection affects primary and secondary metabolism the model Arabidopsis thaliana. Our re...

genetic structure and pathogenic diversity of sclerotinia sclerotiorum, the causal agent of canola white stem rot, were assessed through mycalial compatibility groupings (mcgs), a comparison and comparing of isolate virulence. fifty-seven isolates from three different regions in golestan province were selected for mycelial compatibility and as well for virulence tests. within the 57 tested isol...

RNA silencing is an important mechanism to regulate gene expression and antiviral defense in plants. Nevertheless, RNA silencing machinery in the important oil crop Brassica napus and function in resistance to the devastating fungal pathogen Sclerotinia sclerotiorum are not well-understood. In this study, gene families of RNA silencing machinery in B. napus were identified and their role in res...
