Hop downy mildew (Pseudoperonospora humuli) and hop powdery mildew (Sphaerotheca humuli) are the most important fungal plant diseases of hop (Humulus lupulus). The early detection and diagnosis of pathogens are often aggravated with symptomless before mass infection or commutation with another pathogens. Molecular analysis of internal transcribed spacer (ITS) regions of rDNA is a novel and very...

Downy mildew (DM) of cucumber (Cucumis sativus L.), caused by Pseudoperonospora cubensis, is a devastating disease of cucurbits. resistance is available but is not sufficient to eliminate the need for fungicides to control the disease. previously, the USDA plant Introduction collection of cucumber germplasm was screened in poland and North Carolina, and Ames 2354 was identified as highly resist...

The plant pathogenic fungus Chrysoporthe cubensis was cultivated under solid state employing different substrates and the highest endoglucanase (33.84Ug(-1)), FPase (2.52Ug(-1)), β-glucosidase (21.55Ug(-1)) and xylanase (362.38Ug(-1)) activities were obtained using wheat bran as carbon source. Cellulases and xylanase produced by C. cubensis showed maximal hydrolysis rate at pH 4.0 and in a temp...

Pathogens belonging to the Oomycota, a group of heterokont, fungal-like organisms, are amongst the most notorious pathogens in agriculture. In particular, the obligate biotrophic downy mildews and the hemibiotrophic members of the genus Phytophthora are responsible for a huge variety of destructive diseases, including sudden oak death caused by P. ramorum, potato late blight caused by P. infest...
