New Downstream Signaling Branches of the Mitogen-Activated Protein Kinase Cascades Identified in the Insect Pathogenic and Plant Symbiotic Fungus Metarhizium robertsii [PDF]

Frontiers in Fungal Biology, 2022
Fungi rely on major signaling pathways such as the MAPK (Mitogen-Activated Protein Kinase) signaling pathways to regulate their responses to fluctuating environmental conditions, which is vital for fungi to persist in the environment.

Emulsifiable oils protect Metarhizium robertsii and Metarhizium pingshaense conidia from imbibitional damage [PDF]

Biological Control, 2011
AbstractImbibitional damage (ID) may take place when dehydrated cells are immersed in water and, within certain limits, damage to the plasma membrane is inversely proportional to the immersion temperature. Dried Metarhizium anisopliae conidia formulated in pure oil are not severely impacted when rehydrated in a cold agar-based substrate, whereas dried,

Endophytic Metarhizium robertsii suppresses the phytopathogen, Cochliobolus heterostrophus and modulates  maize defenses. [PDF]

PLoS ONE, 2022
Fungi in the genus Metarhizium (Hypocreales: Clavicipitaceae) are insect-pathogens and endophytes that can benefit their host plant through growth promotion and protection against stresses. Cochliobolus heterostrophus (Drechsler) Drechsler (Pleosporales:

Dark Pigments in Entomopathogenic Fungal Microsclerotia: Preliminary Evidence of a 1,8-Dihydroxynaphthalene-melanin-like Compound in Metarhizium robertsii [PDF]

Journal of Fungi, 2023
Metarhizium robertsii microsclerotia are fungal aggregates composed of compacted, pigmented hyphae. As they are highly tolerant to desiccation and produce infective conidia, they are promising candidates to be formulated as bioinsecticides.

The secretory protein COA1 enables Metarhizium robertsii to evade insect immune recognition during cuticle penetration. [PDF]

Commun Biol
The interplay between the insect immune system and entomopathogenic fungi during cuticle penetration is not yet fully understood. Here, we show that a secretory protein COA1 (coat of appressorium 1) from Metarhizium robertsii, an entomopathogenic fungus ...

Biomass and Extracts of Metarhizium robertsii MT008 as Potential Biopesticides for Controlling the Fruit Fly Anastrepha obliqua. [PDF]

Neotrop Entomol
The fruit fly causes yield losses of 40 to 80% in various fruit crops, resulting in an approximate annual loss of USD 100 million in Colombia. Anastrepha obliqua is a significant pest for the mango production sector.

Transcriptional Differences Guided Discovery and Genetic Identification of Coprogen and Dimerumic Acid Siderophores in Metarhizium robertsii [PDF]

Frontiers in Microbiology, 2021
Siderophores are small molecular iron chelators and participate in the multiple cellular processes in fungi. In this study, biosynthesis gene clusters of coprogens and dimerumic acids were identified by transcriptional level differences of genes related ...

Virulence of <i>Metarhizium robertsii</i> Strains Isolated from Forest Ecosystems Against Wax Moths (<i>Galleria mellonella</i>, <i>Achroia grisella</i>) and Pine Processionary (<i>Thaumetopoea pityocampa</i>) Larvae. [PDF]

Biology (Basel)
Simple Summary Moth pest populations often thrive under rising temperatures, an increasingly challenging consequence of climate change that results in the expansion of their populations to new areas and hosts.

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

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.

Field Efficacy of Metarhizium robertsii (LCM S15) for Controlling Free-Living Stages of Gastrointestinal Nematodes in Goats [PDF]

Pathogens
The rise in anthelmintic resistance in small ruminants has driven the search for sustainable control alternatives. Among these, entomopathogenic fungi such as Metarhizium robertsii stand out for their potential to reduce the free-living stages of ...
