Morphogenetic Alterations of Alternaria alternata Exposed to Dicarboximide Fungicide, Iprodione
Fungicide-resistant Alternaria alternata impede the practical control of the Alternaria diseases in crop fields. This study aimed to investigate cytological fungicide resistance mechanisms of A. alternata against dicarboximide fungicide iprodione. A. alternata isolated from cactus brown spot was cultured on potato-dextrose agar (PDA) with or without iprodione, and the fungal cultures with diffe...
متن کاملMorphological, pathogenic, and molecular characterization of alternaria isolates associated with alternaria late blight of pistachio.
ABSTRACT Alternaria isolates were obtained from various pistachio tissues collected in five orchards in California. For all isolates, morphological characteristics of the colony and sporulation apparatus were determined and compared with those of representative isolates of A. alternata, A. tenuissima, A. arborescens, and A. infectoria. A selection of the pistachio isolates and the representativ...
متن کاملPlant extracts to control Alternaria alternata in Murcott tangor fruits.
BACKGROUND Alternaria alternata causes the Alternaria brown spot disease (ABS) in many tangerines and their hybrids worldwide. Plant extracts offer an alternative method for controlling this disease, which control is based on chemical fungicides. AIMS To identify plant species with antifungal properties against A. alternata, the causal agent of the ABS. METHODS Plant extracts prepared from ...
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 کاملUniversity of Groningen Inheritance and genetic mapping of resistance to Alternaria alternata f . sp . lycopersici in
The fungal pathogen Alternaria alternata f. sp. lycopersici produces AAL-toxins that function as chemical determinants of the Alternar ia stem canker disease in the tomato (Lycopersicon esculentum). In resistant cultivars, the disease is controlled by the Asc locus on chromosome 3. Our aim was to characterize novel sources of resistance to the fungus and of insensit ivity to the host-selective ...
