Characterization of a germination-accelerating factor from the silkworm (Bombyx mori Linnaeus) of entomopathogenic fungus Nomuraea rileyi (Farlow) Samson.
The conidium of the entomopathogenic fungus, Nomuraea rileyi, has been found to germinate rapidly in the presence of a host insect-derived extract. This extract therefore appears to contain an important factor involved in host recognition by N. rileyi, although the substance (germination-accelerating factor, GAF) responsible for such unique germination behavior has yet to be identified. Our pre...
متن کاملIdentification and Expression Analysis of QM-Like Gene From Spodoptera litura After Challenge by the Entomopathogenic Fungus Nomuraea rileyi
A partial sequence of QM homologue was isolated from a Spodoptera litura fatbody suppression subtractive hybridization library. The full-length Spodoptera litura QM (SpLQM) cDNA of 838 bp contains a 5' untranslated region (UTR) of 112 bp, a 3' UTR of 66 bp, and an open reading frame of 660 nucleotides coding for a 219 amino acid peptide with a molecular weight of 25.5 kDa. Analysis of SpLQM seq...
متن کاملMolecular phylogeny of asexual entomopathogenic fungi with special reference to Beauveria bassiana and Nomuraea rileyi.
The phylogenetic lineage, taxonomic affiliation and interrelationships of important asexual entomopathogenic fungal genera were studied using the sequences of partial regions of beta-tubulin and rRNA genes. The species structures of Beauveria bassiana and Nomuraea rileyi were also investigated. A total of 147 fungal entries covering 94 species were analysed. Phylogenetic analysis placed all the...
متن کاملEntomogenous fungus Nomuraea rileyi inhibits host insect molting by C22-oxidizing inactivation of hemolymph ecdysteroids.
The entomogenous fungus Nomuraea rileyi reportedly secretes a proteinaceous substance inhibiting larval molt and metamorphosis in the silkworm Bombyx mori. We studied the possibility that N. rileyi controls B. mori development by inactivating hemolymph molting hormone, ecdysteroids. Incubation of ecdysone (E) and 20-hydroxyecdysone (20E) in fungal-conditioned medium resulted in their rapid modi...
متن کاملPartial Purification and Characterization of Protease Enzyme from Nomuraea Rileyi
Nomuraea rileyi (Farlow) Samson is an entomopathogenic fungus capable of producing a variety of enzymes including proteases and chitinases. Protease derived from microorganisms such as fungi, bacteria, and yeast has established wide spread applications in fields such as in the food, detergent and other industries. This study investigates the strategy for partial purification and characterizatio...
