Differential expression of genes involved in entomopathogenicity of the fungi Metarhizium anisopliae var. anisopliae and M. anisopliae var. acridum (Clavicipitaceae).
Expression analysis of the genes involved in germination, conidiogenisis and pathogenesis of Metarhizium anisopliae during its saprophytic and pathogenic life stages can help plan strategies to increase its efficacy as a biological control agent. We quantified relative expression levels of the nitrogen response regulator gene (nrr1) and a G-protein regulator of genes involved in conidiogenesis ...
متن کاملInhibition of hepatitis B virus gene expression & replication by crude destruxins from Metarhizium anisopliae var. dcjhyium
BACKGROUND & OBJECTIVES Destruxin A, destruxin B and destruxin E isolated from entomopathogenic fungus Metarhizium anisopliae showed a strong suppressive effect on the replication of hepatitis B virus (HBV) in human hepatoma cells. In this study, the anti-HBV effects of the crude destruxins extracted from M. anisopliae var. dcjhyium were detected both in vitro and in vivo. METHODS HepG2.2.15 ...
متن کاملSporulation Characteristics and Virulence of Metarhizium anisopliae Against Subterranean Termites (Coptotermes formosanus)
In the present study, four fungal isolates (Metarhizium anisopliae) were isolated and examined for their sporulation characteristics and virulence against Coptotermes formosanus. Initially fungal strains were isolated through insect bait (Galleria) method. The mortality was significantly varied between 2 to 4 days. nd th In in this study inspection, the mortality of termites was observed after ...
متن کاملErratum to “Use of Metarhizium anisopliae Chitinase Genes for Genotyping and Virulence Characterization”
Virulence is the primary factor used for selection of entomopathogenic fungi (EPF) for development as biopesticides. To understand the genetic mechanisms underlying differences in virulence of fungal isolates on various arthropod pests, we compared the chitinase genes, chi2 and chi4, of 8 isolates of Metarhizium anisopliae. The clustering of the isolates showed various groups depending on their...
متن کاملEVALUATION OF Metarhizium anisopliae var. anisopliae Qu-M845 ISOLATE TO CONTROL Varroa destructor (Acari: Varroidae) IN LABORATORY AND FIELD TRIALS
The effectiveness of the Metarhizium anisopliae (Metschinkoff) Qu-M845 isolate was evaluated in laboratory and field trials. It was previously selected for thermal resistance (at 30 and 35 oC) and pathogenicity on Varroa destructor (Anderson and Trueman). In the laboratory, the first evaluations were carried out by spraying and increasing the concentration from zero to 108 conidia mL-1 on varro...
