THE EVOLUTIONARY TRAJECTORY OF METARHIZIUM ROBERTSII ENDOPHYTIC CAPABILITY AND ENTOMOPATHOGENICITY
Metarhizium fungi are a keystone genus of soil-inhabiting ascomycetes providing essential ecosystem services as saprotrophs, plant symbionts and insect pathogens, among other roles. Recent studies have looked at how Metarhizium niches have evolved and shaped genome evolution over large time scales within the Metarhizium genus.

A High-Throughput Gene Disruption Methodology for the Entomopathogenic Fungus Metarhizium robertsii
PLoS ONE, 2014 Systematic gene disruption is a direct way to interrogate a fungal genome to functionally characterize the full suite of genes involved in various biological processes. Metarhizium robertsii is extraordinarily versatile, and it is a pathogen of arthropods, a saprophyte and a beneficial colonizer of rhizospheres. Thus, M.

The Effect of Bean Seed Treatment with Entomopathogenic Fungus Metarhizium robertsii on Soil Microarthropods (Acari, Collembola). [PDF]
Insects, 2022 The treatment of agricultural crops with entomopathogenic fungi may disturb the structure of soil microarthropod communities, which can have an adverse impact on soil fertility and, ultimately, on the yield.

Roles of BrlA and AbaA in Mediating Asexual and Insect Pathogenic Lifecycles of Metarhizium robertsii [PDF]
J Fungi (Basel), 2022 BrlA and AbaA are key activators of the central developmental pathway (CDP) that controls asexual development in Aspergillus but their roles remain insufficiently understood in hypocerealean insect pathogens. Here, regulatory roles of BrlA and AbaA orthologs in Metarhizium robertsii (Clavicipitaceae) were characterized for comparison to those ...

Bioremediation of mercury-polluted soil and water by the plant symbiotic fungus Metarhizium robertsii. [PDF]
Proc Natl Acad Sci U S A, 2022 Fungi are central to every terrestrial and many aquatic ecosystems, but the mechanisms underlying fungal tolerance to mercury, a global pollutant, remain unknown. Here, we show that the plant symbiotic fungus Metarhizium robertsii degrades methylmercury and reduces divalent mercury, decreasing mercury accumulation ...

Plants, 2021 This paper investigates 71 isolates of two genera of entomopathogens, Metarhizium and Beauveria, and a biostimulative genus Trichoderma, for their ability to infect yellow mealworms (Tenebrio molitor) and to stimulate maize (Zea mays) growth.

Functional Analysis of Keto-Acid Reductoisomerase ILVC in the Entomopathogenic Fungus Metarhizium robertsii. [PDF]
J Fungi (Basel), 2021 Ketol-acid reductoisomerase (ILVC) is the second enzyme in the branched-chain amino acid (BCAA) biosynthesis, which regulates many physiological activities in a variety of organisms from bacteria to fungi and plants. In this work, function mechanisms of ILVC in Metarhizium robertsii Metchnikoff (Hypocreales: Clavicipitaceae) were explored with site ...

Scientific Reports, 2021 Metarhizium robertsii is an insect pathogen as well as an endophyte, and can antagonize the phytopathogen, Fusarium solani during bean colonization. However, plant immune responses to endophytic colonization by Metarhizium are largely unknown. We applied

Activation of microlipophagy during early infection of insect hosts by Metarhizium robertsii. [PDF]
Autophagy, 2022 The requirement of macroautophagic/autophagic machinery for filamentous fungal development and pathogenicity has been recognized, but the underlying effects and mechanisms remain elusive. The insect pathogenic fungus Metarhizium robertsii infects hosts by cuticular penetration through the formation of the infection structure appressoria.

Production of destruxins from Metarhizium spp. fungi in artificial medium and in endophytically colonized cowpea plants. [PDF]
PLoS ONE, 2014 Destruxins (DTXs) are cyclic depsipeptides produced by many Metarhizium isolates that have long been assumed to contribute to virulence of these entomopathogenic fungi.
