The purified isolates were identified based on the described characteristics of Alternaria genus (i.e., macroscopic and microscopic characteristics, including size, color, number of longitudinal and transverse walls, presence of surface ornamentation, presence and absence of the tip, length, and size of conidiophore, and presence or absence of ...

2021年8月23日 · We exploited 220 single nucleotide polymorphisms derived from DNA sequences of 10 microsatellite loci to analyse the population genetic structure between species and between populations within...

Alternaria Fungi Classifications, Characteristics and Pathogenesis. Alternaria is a large genus that belongs to phylum Ascomycota (Sac fungi). A majority of Alternaria species are saprobic, which means that they are largely involved in the decomposition of various organic matter.

We exploited 220 single nucleotide polymorphisms derived from DNA sequences of 10 microsatellite loci to analyse the population genetic structure between species and between populations within species and infer the mode of reproduction. High genetic variation and genotypic diversity were observed in all the populations analysed.

Using a light microscope (40 magnification), the developing Alternaria spp. were studied and morphologically characterized based on macro- and microscopic features such as conidia color, size, septation, conidiophore branching, and catenulate conidia diameters.

2014年9月1日 · The three known Alternaria pathogens causing early blight on tomato all cluster in one clade, and are synonymised under the older name, A. linariae. Alternaria protenta, a species formerly only known as pathogen on Helianthus annuus, is also reported to cause early blight of potato, together with A. solani and A. grandis.

2018年1月1日 · The genus Alternaria, alternarioid hyphomycetes, comprise a biologically, ecologically, and morphologically rich group of fungi that has suffered from taxonomic flux for many years.

Win et al. (2020) evaluated the potential of utilizing Ag NPs fabricated using Alternaria sp. showing a greater antifungal activity against phytopathogens such as Fusarium spp., and Alternaria...

2024年7月8日 · The study investigated early blight, a major fungal disease affecting tomatoes, across two distinct agroclimatic zones in India, resulting in a collection of 90 Alternaria isolates. Morpho-cultural characterization grouped these isolates into 11 putative clusters, which were subjected to further analysis.
