Analysis of variation in Alternaria alternata by pathogenicity and RAPD study.
Alternaria alternata were isolated and identified from root, foliage and soil of both wheat and rice crops and their aggressiveness was studied using aggressiveness analysis. Isolates of Alternaria alternata were genetically characterized using RAPD's. The investigations were based on surveys of wheat and rice crops in the rice-wheat cropping areas of Pakistan. The study showed that Alternaria ...
متن کاملA conditionally dispensable chromosome controls host-specific pathogenicity in the fungal plant pathogen Alternaria alternata.
The filamentous fungus Alternaria alternata contains seven pathogenic variants (pathotypes), which produce host-specific toxins and cause diseases on different plants. Previously, the gene cluster involved in host-specific AK-toxin biosynthesis of the Japanese pear pathotype was isolated, and four genes, named AKT genes, were identified. The AKT homologs were also found in the strawberry and ta...
متن کاملStress Response and Pathogenicity of the Necrotrophic Fungal Pathogen Alternaria alternata
The production of host-selective toxins by the necrotrophic fungus Alternaria alternata is essential for the pathogenesis. A. alternata infection in citrus leaves induces rapid lipid peroxidation, accumulation of hydrogen peroxide (H2O2), and cell death. The mechanisms by which A. alternata avoids killing by reactive oxygen species (ROS) after invasion have begun to be elucidated. The ability t...
متن کاملEstablishment of CRISPR/Cas9 in Alternaria alternata.
The filamentous fungus Alternaria alternata is a potent producer of many secondary metabolites, some of which like alternariol or alternariol-methyl ether are toxic and/or cancerogenic. Many Alternaria species do not only cause post-harvest losses of food and feed, but are aggressive plant pathogens. Despite the great economic importance and the large number of research groups working with the ...
متن کاملA review of Alternaria alternata sensitivity.
Sensitivity to fungi is a major risk factor for the development of asthma. However, the prevalence of fungal sensitivity in asthma is not completely understood. Nonetheless upward of 80% of asthmatic patients may be sensitized to one or more fungi. Fungal exposure occurs primarily from outdoors sources, but can occur in the indoor environment as well. Assessment of fungal exposure requires a mu...
