Parasexuality in the deuteromycete Metarhizium anisopliae

Transactions of the British Mycological Society, 1980
Auxotrophic and conidial colour mutants of Metarhizium anisopliae var. minor were obtained after ultraviolet treatment and used to demonstrate parasexual recombination. Heterokaryons between different mutants revealed that spore colour is non-autonomous. From heterokaryons, putative diploids were isolated.

Depsipeptides from Metarhizium anisopliae

Phytochemistry, 1981
Abstract From the culture medium of a strain of Metarhizium anisopliae , 14 depsipeptides have been isolated. Five of them were identified as known destruxins A, B, C, D and desmethyldestruxin B. The structures of the new compounds, named destruxins E, A 1 , A 2 , B 1 , B 2 , C 2 , D 1 , D 2 and E 1 ,were established mainly from the mass spectral ...

Localization of the insect pathogenic fungal plant symbionts Metarhizium robertsii and Metarhizium brunneum in bean and corn roots

Fungal Biology, 2020
Metarhizium is an insect pathogenic fungus and a plant root symbiont. Here the root association patterns (rhizoplane or endophytic colonization) were analyzed in common beans (Phaseolus vulgaris) and sweet corn (Zea mays) using M. robertsii and M. brunneum under various vermiculite treatments (control, with sucrose, with an insect) at two time points ...

Efficacy and Ultrastructural Impact of Metarhizium anisopliae and Metarhizium robertsii on Myllocerus subfasciatus

Journal of Basic Microbiology
ABSTRACTThe ash weevil, Myllocerus subfasciatus, is a significant insect pest that infests brinjal. Both the adults and grubs feed on the leaves and roots, respectively, leading to considerable yield loss. The subterranean habits of the larvae limit the effectiveness of insecticide applications, necessitating the implementation of integrated pest ...

Electrophoretic karyotype of Metarhizium anisopliae

Journal of Invertebrate Pathology, 1992
Abstract The chromosomal DNA molecules of Metarhizium anisopliae var. anisopliae have been separated into seven bands by pulsed-field gel electrophoresis. Using the Schizosaccharomyces pombe chromosomes as size standards, we estimate the size of the chromosomes to be between 1.6 and 7.4 megabase pairs (Mbp) and total genome sizes of the five isolates

Virulence Factors of the Entomopathogenic Genus Metarhizium

Current Protein & Peptide Science, 2020
: The fungal genus Metarhizium has been used as an entomopathogen worldwide for approximately 140 years, and its mechanism of infection and its virulence factors have been studied. The present review is a compilation of virulence factors described in the literature to date and their participation in specific stages of the infection process.

Biogeography and genotypic diversity of Metarhizium brunneum and Metarhizium robertsii in northwestern North American soils

Canadian Journal of Microbiology, 2019
The biogeography and genotype diversity of Metarhizium species in northwestern North American soils was examined; 20 ecoregions were sampled, including 58 agricultural and 80 natural habitat subsites, and areas that were glaciated during the Pleistocene epoch. One hundred and twenty-nine isolates of M. brunneum, 26 isolates of M.

Stress is the rule rather than the exception for Metarhizium

Current Genetics, 2014
The insect pathogenic plant root symbiont Metarhizium experiences many situations that restrict its growth whether living in host insects or on plant roots. These include a range of physical, chemical and biological effects involving UV and extremes of temperature, pH, nutrient availability, toxic metals and other pollutants, and insect host defenses ...

[Variability in esterases of Metarhizium anisopliae].

Revista iberoamericana de micologia, 2005
The variability in esterases of the entomogenous fungus Metarhizium anisopliae was determined electrophoretically on 8.5% polyacrylamide gel. Ten isolates from diverse taxonomic groups of insects were analyzed. The electrophoretic analysis showed differences and similarities between these isolates and it was possible to distinguish six different ...

Biodiversity of Metarhizium From Korea and Pathogenicity Screening of Two Unrecorded Species Metarhizium lepidiotae and Metarhizium robertsii

Entomological Research
ABSTRACTThis study analyzed the biodiversity of entomopathogenic fungi Metarhizium species isolated from Korean soil samples and insect cadavers. Morphological characteristics and molecular phylogenetic analyses were used to analyze Korean species diversity. Concatenated datasets of three genes, the translation elongation factor 1‐a (TEF), DNA‐directed
