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.

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 ...

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.

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.

The transcription factor MrbHLH2 significantly affects stress resistance and insect virulence in Metarhizium robertsii.

Fungal Biology
Basic helix-loop-helix (bHLH) transcription factors are essential regulators of various biological processes, including growth, development, and stress responses in eukaryotes.

Only one of three hydrophobins (Hyd1-3) contributes to conidial hydrophobicity and insect pathogenicity of Metarhizium robertsii.

Journal of Invertebrate Pathology, 2023
Class I/II hydrophobins constitute a family of small amphiphilic proteins that mediate cell hydrophobicity and adhesion to host or substrata and have pleiotropic effects in filamentous fungi.

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.

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

Entomological Research
This 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 ...

Congo red induces trans-priming to UV-B radiation in Metarhizium robertsii

Fungal Biology, 2023
Metarhizium spp. is used as a biocontrol agent but is limited because of low tolerance to abiotic stress. Metarhizium robertsii is an excellent study model of fungal pathogenesis in insects, and its tolerance to different stress conditions has been extensively investigated.
