In the present investigation five pathogenic fungal isolates such as Alternaria alternata, Alternaria macrospora MKP2, Alternaria macrospora MKP4 Alternaria sp. PMK1 and Alternaria sp. PMK2, were isolated from diseased leaves of parthenium plant and found to be pathogenic to this weed. Isolated pathogens were screened qualitatively and quantitatively for lignocellulolytic activities. All the fu...

BERNADOVIČOVÁ, S., IVANOVÁ, H. 2011. Hyphomycetes and Coelomycetes fungi isolated from affected leaves and twigs of cherry laurel trees. Folia oecol., 38: 137–145. The aim of this work was to identify fungi occurring on leaves and twigs of Prunus laurocerasus L. Mycological observations were carried out on leaves and twigs collected from symptomatic cherry laurels growing in green areas of the ...

Diseases caused by Alternaria sp. are among the most common diseases of crops throughout the world. Alternaria sp. is a common component of the flora of wheat seed. Although isolation of Alternaria sp. from wheat (Triticum aestivum) seed has been reported in Argentina, development of the Alternaria blight in plants from infected seeds has not been demonstrated experimentally. Seed transmission ...

The obligate bitrophic fungus Puccinia striiformis f. sp. tritici (Pst) causes stripe (yellow) rust on wheat worldwide. Here, we report a novel fungal strain able to hyperparasitize Pst. The strain was isolated from gray-colored rust pustules, and was identified as Alternaria alternata (Fr.: Fr.) keissler based on a combination of morphological characteristics and multi-locus (ITS, GAPDH, and R...

Trichoderma asperellum is one of the plant growth-promoting fungi (PGPF) presently marketed as biopesticide, biofertilizer and in soil amendments, due to its ability protect plants, enhance vegetative growth reduce pathogen populations. Keeping this view, here, we assessed efficacy against pathogens medicinal plants vitro field conditions Leaf spot disease Green leaf Tulsi (Ocimum basilicum). W...

Alternaria alternata is one of the most studied fungi to date because of its impact on human life - from plant pathogenicity to allergenicity. However, its sesquiterpene emissions have not been systematically explored. Alternaria regularly co-occurs with Fusarium fungi, which are common plant pathogens, on withering plants. We analyzed the diversity and determined the absolute quantities of vol...

The endophytic microbiome uses mechanisms such as the secretion of diffusible antibiotic molecules, synthesis and release volatile organic compounds, and/or toxins to protect plants. aim this research was study compounds (VOCs) profile well secondary metabolites produced released by bacteria isolated from tomato plants that in in-vitro assays prevented growth pathogenic fungi. Bacteria belongin...

A total of 99 strains of 11 Alternaria species, including 68 strains of seven fungi known to produce host-specific toxins, were subjected to analysis of restriction fragment length polymorphism (RFLP) in nuclear ribosomal DNA (rDNA). Total DNA was digested with XbaI, and the Southern blots were probed with a nuclear rDNA clone of Alternaria kikuchiana. The hybridization gave 17 different RFLPs ...
