A novel ascochlorin glycoside from the insect pathogenic fungus Verticillium hemipterigenum BCC 2370.
Vertihemipterin A, the ascochlorin glycoside, and its aglycone, 4',5'-dihydro-4'-hydroxyascochlorin, were isolated from the insect pathogenic fungus Verticillium hemipterigenum BCC 2370. A new analog, 8'-hydroxyascochlorin, and five known compounds, ascochlorin, LL-Z1272delta, 8',9'-dehydroascochlorin, ascofuranone and ascofuranol, were also isolated from the same fermentation broth. Structures...
متن کاملDraft Genome Sequence and Gene Annotation of the Entomopathogenic Fungus Verticillium hemipterigenum.
Verticillium hemipterigenum (anamorph Torrubiella hemipterigena) is an entomopathogenic fungus and produces a broad range of secondary metabolites. Here, we present the draft genome sequence of the fungus, including gene structure and functional annotation. Genes were predicted incorporating RNA-Seq data and functionally annotated to provide the basis for further genome studies.
متن کاملProduction of extracellular enzymes in the entomopathogenic fungus Verticillium lecanii
This study investigates the mechanisms as well as strategies for purification and characterization of potential enzymes involved in pathogenesis of entomopathogenic fungi. The test strain of Verticillium lecanii that was screened, during the present investigation, proved to be an efficient producer of protein and polysaccharide degrading enzymes (amylase, protease, and lipase), hence indicating...
متن کاملIsolation, partial characterization, and cloning of an extracellular chitinase from the entomopathogenic fungus Verticillium lecanii.
The entomopathogenic fungus Verticillium lecanii is a well-known biocontrol agent of fungal phytopathogens, as well as insect pests. A 42-kDa chitinase belonging to family 18 of the glycosyl hydrolases was isolated and partially characterized. Chitinase was purified using successive column chromatography on phenyl-sepharose, DEAE-sepharose, and CM-sepharose. The enzyme showed the highest activi...
متن کاملIsolation and characterization of a chitinase gene from entomopathogenic fungus Verticillium lecanii
Entomopathogenic fungus Verticillium lecanii is a promising whitefly and aphid control agent. Chitinases secreted by this insect pathogen have considerable importance in the biological control of some insect pests. An endochitinase gene Vlchit1 from the fungus was cloned and overexpressed in Escherichia coli. The Vlchit1 gene not only contains an open reading frame (ORF) which encodes a protein...
