The analysis of gene transcripts associated with conidiation in the insect pathogenic fungus, Metarhizium anisopliae /
Conidia of the insect pathogenic fungus, Metarhizium anisopliae play an important role in pathogenicity because they are the infective propagules that adhere to the surface of the insect, then germinate and give rise to hyphal penetration of the insect cuticle. Conidia are produced in the final …

The double life of an insect pathogen: Metarhizium as a plant symbiont and its genetic diversity in coffee agroecosystems
The Metarhizium genus is widely recognized for its entomopathogenic capacity, but more recently was recognized as a plant symbiont, being able to transfer nitrogen from insect cadavers to plants, act as plant pathogen antagonist and plant growth promoter. All those functions could be valuable as …

The analysis of Metarhizium robertsii potential as endophytic plant root coloniser, plant growth enhancer and antagonist to bean root pathogen Fusarium solani f. sp. phaseolis.
The soil-inhabiting insect-pathogenic fungus Metarhizium robertsii also colonizes plant roots endophytically, thus showing potential as a plant symbiont. M robertsii is not randomly distributed in soils but preferentially associates with the plant rhizosphere when applied in agricultural settings. …
