Abstract. This review addresses the current knowledge on phytotoxic roles of tenuazonic acid and its biosynthesis in Alternaria. We examine recent advances this toxin produced by A. alternata other fungi; pathogenicity mechanisms that molecule displays to exert bioherbicidal activity; risks for human animal health involved using versus a native mix toxins alternata. Finally, we discuss potentia...

BACKGROUND Exposure to the fungal allergen Alternaria alternata as well as ryegrass pollen has been implicated in severe asthma symptoms during thunderstorms. We have previously shown that Alternaria extract induces innate type 2 lung inflammation in mice. We hypothesized that the innate eosinophilic response to Alternaria extract may enhance lung inflammation induced by ryegrass. METHODS Mic...

BACKGROUND The fungal allergen Alternaria alternata is implicated in severe asthma and rapid onset life-threatening exacerbations of disease. However, the mechanisms that underlie this severe pathogenicity remain unclear. OBJECTIVE We sought to investigate the mechanism whereby Alternaria was capable of initiating severe, rapid onset allergic inflammation. METHODS IL-33 levels were quantifi...

In this paper, thermal (8-13 µm) and hyperspectral imaging in visible and near infrared (VNIR) and short wavelength infrared (SWIR) ranges were used to elaborate a method of early detection of biotic stresses caused by fungal species belonging to the genus Alternaria that were host (Alternaria alternata, Alternaria brassicae, and Alternaria brassicicola) and non-host (Alternaria dauci) pathogen...

The alkaloid securinine was assessed against spore germination of some plant pathogenic and saprophytic fungi (Alternaria alternata, Alternaria brassicae, Alternaria brassicicola, Curvularia lunata, Curvularia maculans, Curvularia pallenscens, Colletotrichum musae, Colletotrichum sp., Erysiphe pisi, Helminthosporium echinoclova, Helminthosporium spiciferum, Heterosporium sp.). Spore germination...

Many root diseases can cause serious damage to tomato (Solanum lycopersicum L.) production during the seedling growth period, particularly Rhizoctonia solani, Pythium spp., and Alternaria spp. Paclobutrazol (PBZ) has proved reduce of blight disease on seedlings. The present investigation was designated evaluate infected seedlings with R. solani under applications Trichoderma harzianum alone, PB...

Chamaecyparis lawsonia, which brings beauty in parks and green space, is attacked by a variety of pathogenic agents specially fungi. In this study, some Chamaecyparis lawsonia available in parks that had disease symptoms were  sampled. After sample collection, in order to isolate fungal pathogens, cuts of the infected plant tissues were placed on PDA (potato dextrose agar) and later were put on...

background cereal products are susceptible to mould damage during pre- and post-harvesting stages of the production. the regional specificity of golestan province in the northern region of of iran, with its high temperature and high relative humidity, acts as a leading factor for the growth of aflatoxin-producing fungi. it is well known that contamination of starch-based ingredients with mycoto...
