Genetic basis of destruxin production in the entomopathogen Metarhizium robertsii

Current Genetics, 2012
Destruxins are among the most exhaustively researched secondary metabolites of entomopathogenic fungi, yet definitive evidence for their roles in pathogenicity and virulence has yet to be shown. To establish the genetic bases for the biosynthesis of this family of depsipeptides, we identified a 23,792-bp gene in Metarhizium robertsii ARSEF 2575 ...

Nitrogen-starvation triggers cellular accumulation of triacylglycerol in Metarhizium robertsii

Fungal Biology, 2018
Nitrogen starvation can induce cellular triacylglycerol (TAG) accumulation in different organisms with an unclear mechanism. In this study, we performed nutrient starvation and lipid droplet (LD) proteomics analyses of the filamentous fungus Metarhizium robertsii.

Overexpression of a Metarhizium robertsii HSP25 gene increases thermotolerance and survival in soil

Applied Microbiology and Biotechnology, 2013
Temperature extremes are an important adverse factor limiting the effectiveness of microbial pest control agents. They reduce virulence and persistence in the plant root-colonizing insect pathogen Metarhizium robertsii. Small heat shock proteins have been shown to confer thermotolerance in many organisms.

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 ...

The Polyubiquitin Gene MrUBI4 Is Required for Conidiation, Conidial Germination, and Stress Tolerance in the Filamentous Fungus Metarhizium robertsii

Genes, 2019
The polyubiquitin gene is a highly conserved open reading frame that encodes different numbers of tandem ubiquitin repeats from different species, which play important roles in different biological processes.

Dicer and Argonaute Genes Involved in RNA Interference in the Entomopathogenic Fungus Metarhizium robertsii [PDF]

Applied and Environmental Microbiology, 2017
ABSTRACT RNA interference (RNAi) is a gene-silencing mechanism that plays an important role in gene regulation in a number of eukaryotic organisms. Two core components, Dicer and Argonaute, are central in the RNAi machinery.

Metarhizium robertsii morphological flexibility during nonylphenol removal

International Biodeterioration & Biodegradation, 2014
Nonylphenols (NPs) are toxic organic pollutants that cause deleterious effects in various ecosystems. It was formerly documented by us that the cosmopolitan non-ligninolytic fungus Metarhizium robertsii is capable of degrading 4-n-nonylphenol (4-n-NP) with significant efficiency (initial xenobiotic content 50 mg l−1). The present study revealed that M.

Biosynthesis of non-melanin pigment by a divergent polyketide synthase in Metarhizium robertsii

Fungal Genetics and Biology, 2015
Fungal polyketide synthases (PKSs) and their related gene clusters are highly diversified at both inter- and intra-specific levels. The most well characterized PKS enzymes include those responsible for the biosynthesis of polyketide pigments such as melanins.

Zeolite substrate characterization for Metarhizium robertsii inoculation

Biointerphases
For this study, zeolite powder served as a substrate for inoculating Metarhizium robertsii to demonstrate the biocompatibility between the entomopathogenic fungus and the zeolite mineral, as the initial step in developing a biological control agent.

Identification of a novel polymycovirus infecting the entomopathogenic fungus Metarhizium robertsii

Archives of Virology
Mycoviruses studies have been increasing in the last few years. Most of them are focused on the ability of the virus to positively or negatively affect the virulence of their host. Hypervirulence-associated mycoviruses infecting important entomopathogenic fungi such as Metarhizium anisopliae or Beauveria bassiana increase their pathogenicity against ...
