Significance Recently emerged fungal diseases are contributing toward global declines in wildlife, but the mechanisms for emergence of new pathogenic fungi remain mysterious. The entomopathogen Metarhizium robertsii evolved from plant symbionts, and here we report that this host shift was facilitated by 18 horizontal gene transfers (HGTs). necessity breaching cuticular barriers selected retention these genes, as 12 up-regulated during penetration, their collective actions indispensable...

Summary M etarhizium robertsii has been used as a model to study fungal pathogenesis in insects, and its pathogenicity many parallels with plant mammal pathogenic fungi. MAPK (Mitogen‐activated protein kinase) cascades play pivotal roles cellular regulation fungi, but their functions have not characterized . In this study, we identified the full complement of cascade components dissected regulatory pathogenesis, conidiation stress tolerance. The nine Fus3, Hog1 Slt2‐ are all involved...

Abstract Metarhizium robertsii is a versatile fungus with saprophytic, plant symbiotic and insect pathogenic lifestyle options. Here we show that M. mediates the saprophyte-to-insect pathogen transition through modulation of expression membrane protein, Mr-OPY2. Abundant Mr-OPY2 protein initiates appressorium formation, prerequisite for infection, whereas reduced production elicits saprophytic growth conidiation. The precise regulation achieved via alternative transcription start sites....

The ecological importance of the duplication and diversification gene clusters that synthesize secondary metabolites in fungi remains poorly understood. Here, we demonstrated subsequent a cluster produced two polyketide synthase cosmopolitan fungal genus Metarhizium. Diversification occurred promoter regions exon-intron structures Pks paralogs (Pks1 Pks2). These genes have distinct expression patterns, with Pks1 highly expressed during conidiation Pks2 infection. Different upstream signaling...

As a type of multicopper oxidase, laccases play multiple biological roles in entomopathogenic fungi, enhancing their survival, development, and pathogenicity. However, the mechanisms by which operate these fungi remain under-researched. In this study, we identified two laccase-encoding genes, Mr-lac3 Mr-lcc2, from Metarhizium robertsii, both are highly expressed during conidiation. Knocking out Mr-lcc2 resulted significant increase conidial yields M. robertsii. Furthermore, relative...

However, its contamination fungi mycotoxins poses serious health risks when used medicinally. Thus, identifying in controlling fungal toxins crucial. This study employs high-throughput sequencing to detect samples analyze their correlation mycotoxin content. Our findings showed no infection from filling maturity, but diverse community was present mature seeds, the relative...

Summary Metarhizium robertsii occupies a wide array of ecological niches and has diverse lifestyle options (saprophyte, insect pathogen plant symbiont), that renders it an unusually effective model for studying genetic mechanisms fungal adaptation. Here over 20,000 M. T‐DNA mutants were screened in order to elucidate mechanism by which replicates persists niches. About 287 conidiation, colony sectorization or pathogenicity loci, many have not been reported other fungi identified. By...

Nigrospora nonsegmented RNA virus 1 (NoNRV1) has been reported previously in the fungus oryzae, but its biological effects on host are unknown. In this work, we isolated a strain 9-1 of N. oryzae from chrysanthemum leaf and identified NoNRV1 infection strain. The genome sequence here is highly homologous to that isolate HN-21 reported; thus, tentatively designated newly as NoNRV1-ZJ. Drug treatment with Ribavirin successfully removed NoNRV1-ZJ 9-1, which provided us an ideal control...
