in vitro antifungal activity of silver nanoparticles, at concentrations of 6, 8, 10, 12, 14 and 16 ppm, was studied on five phytopathogenic fungi, and a biocontrol agent. then effect of silver nanoparticle at 6 ppm (optimum concentration) was evaluated on macrophomina phaseolina in greenhouse. for in vitro experiment, the fungal isolates were grown on potato dextrose agar medium amended with si...

Sclerotinia sclerotiorum is a necrotrophic, omnivorous plant pathogen with worldwide distribution. Sclerotia of S. sclerotiorum are pigmented, multihyphal structures that play a central role in the life and infection cycles of this pathogen. Calcineurin, a Ser/Thr phosphatase linked to several signal-transduction pathways, plays a key role in the regulation of cation homeostasis, morphogenesis,...

The ascomycete Sclerotinia sclerotiorum is a plant pathogen with a very broad host range. In order to identify and characterize genes involved in S. sclerotiorum infection of Brassica napus (canola), expressed sequence tags (ESTs) were examined from libraries prepared from three tissues: complex appressorium (infection cushions), mycelia grown on agar and lesions formed on leaves of B. napus. A...

WRKY transcription factors are known to participate in the defence responses of higher plants. However, little is known about the roles of such proteins, especially regarding their functions in the resistance of oilseed rape (Brassica napus) to Sclerotinia sclerotiorum, a necrotrophic fungal pathogen that causes stem rot. In this study, we identified BnWRKY33 as a S. sclerotiorum-responsive gen...

White mold, caused by Sclerotinia sclerotiorum (Lib.) de Bary, can be a serious disease of crops grown under cool, moist environments. In many plants, such as soybean [Glycine max (L.) Merr.], complete genetic resistance does not exist. To identify possible genes involved in defense against this pathogen, and to determine possible physiological changes that occur during infection, a microarray ...

Coniothyrium minitans is an important mycoparasite of Sclerotinia sclerotiorum. In addition, it also produces small amounts of antifungal substances. ZS-1TN1812, an abnormal mutant, was originally screened from a T-DNA insertional library. This mutant showed abnormal growth phenotype and could significantly inhibit the growth of S. sclerotiorum when dual-cultured on a PDA plate. When spraying t...

ABSTRACT Sclerotinia sclerotiorum is a necrotrophic pathogen that devastates the yields of numerous crop species, including beans. The disease in common bean and pea is referred to as white mold. We examined the relationship between oxalate, an established virulence factor of S. sclerotiorum, and partial white mold resistance of scarlet runner bean (Phaseolus coccineus). P. coccineus genotypes ...

brassica napus is an important oilseed crop and the yield loss due to fungal disease stem rot caused by sclerotinia sclerotiorum is a serious problem in cultivation of this crop. the pathogenesis-related (pr) protein, glucanase, hydrolyzes a major cell wall component, glucan, of the pathogenic fungi and acts as a plant defense barrier. in this study, a β-1,3-glucanase (bgn13.1) gene was isolate...
