Elicitins are a family of structurally related proteins that induce hypersensitive response in specific plant species. Two Phytophthora infestans cDNAs, inf2A and inf2B, potentially encoding novel elicitin-like proteins, were isolated from a cDNA library made from infected potato tissue. Multiple sequence alignments and phylogenetic analyses of 19 elicitins and elicitin-like proteins from nine ...

four sugar beet genotypes with different reactions to root rot pathogens were evaluated for resistance to important root rot agents including pythium aphanidermatum, phytophthora drechsleri, rhizoctonia solani ag-2-2 and r. solani ag-4. inoculums for pythium and phytophthora were 3-5 day actively growing colony of the pathogens on cma medium, while for rhizoctonia isolates were nine infected co...

Aims: Aim of this study was to elucidate association Pythium isolates without forming sexual structures on root rot hydroponically grown Welsh onion, as well clarify their taxonomic positions.
 Place and Duration Study: Commercial hydroponic greenhouses in Hiroshima Prefecture, Prefectural Technology Research Institute, Osaka Metropolitan University, between March 2020 2021.

Yerba mate, Ilex paraguariensis A. St. Hil. (Aquifoliaceae), waste is one of the most common byproducts generated in households southern Brazil due to traditional consumption mate. However, decomposition this by fungi has not been thoroughly evaluated. In order study fungal succession mate residue, 450 samples were evaluated during autumn, winter, and spring, kept for two months a humid chamber...

Root rot is an important and widespread disease that often causes significant reduction in the yield and quality of harvested peas throughout the production areas in New York. Pea root rot can be caused by one of several soilborne pathogens or various combinations of root pathogens and also non-pathogens. In recent years, Fusarium solani f. sp. pisi (causal pathogen of Fusarium root rot) has be...

During a study on the occurrence and pathogenicity of oomycetes in the reed-belt (Phragmites australis) of Lake Constance (Germany), a new Pythium resembling the important cereal pathogen species complex P. arrhenomanes/P. graminicola was consistently isolated from necrotic mature reed leaves and reed rhizosphere samples. The new species proved to be significantly more aggressive towards reed l...
