Diversity of glycosil hydrolase family 18 genes in environment isolates of the entomopathogenic fungus Metarhizium anisopliae
Backgound Metarhizium anisopliae is a model for host-pathogen studies due to its ability to infect several different arthropods. The first barrier to accomplish successful host-infection is transverse the host cuticle, which is a rigid chitin-rich structure. To surpass this barrier, the fungus produces several hydrolytic enzymes, among which are chitinases and endo-b-N-acetylglucosaminidases, g...
متن کاملIsolation, characterization and expression analysis of the ornithine decarboxylase gene (ODC1) of the entomopathogenic fungus, Metarhizium anisopliae.
The gene ODC1, which codes for the ornithine decarboxylase enzyme, was isolated from the entomopathogenic fungus, Metarhizium anisopliae. The deduced amino acid sequence predicted a protein of 447 amino acids with a molecular weight of 49.3 kDa that contained the canonical motifs of ornithine decarboxylases. The ODC1 cDNA sequence was expressed in Escherichia coli cells; radiometric enzyme assa...
متن کاملSusceptibility of Seven Termite Species (Isoptera) to the Entomopathogenic Fungus Metarhizium anisopliae
Seven termite species (Isoptera) from five families were tested for disease susceptibility against the entomopathogenic fungus Metarhizium anisopliae using a standard protocol: Mastotermes darwiniensis (Mastotermitidae), Hodotermopsis sjoestedti (termopsidae), Hodotermes mossambicus (Hodotermitidae), Kalotermes flavicollis (Kalotermitidae), Reticulitermes flavipes and Prorhinotermes canalifrons...
متن کاملLaboratory evaluation of three strains of the entomopathogenic fungus Metarhizium anisopliae for controlling Hyalomma anatolicum anatolicum and Haemaphysalis punctata
Hyalomma anatolicum anatolicum and Haemaphysalis punctata larval ticks were shown to be susceptible to different strains of entomopathogenic fungi Metarhizium anisopliae under laboratory conditions. To determine the susceptibility of H. anatolicum anatolicum and H. punctata to M. anisopliae, two suspensions of conidia were used (103 and 104 spores/ml). The treatments were conducted by immersing...
متن کاملThe entomopathogenic fungus Metarhizium anisopliae alters ambient pH, allowing extracellular protease production and activity.
Ambient pH regulates the expression of virulence genes of Metarhizium anisopliae, but it was unknown if M. anisopliae can regulate ambient pH. Mutants of M. anisopliae altered in production of oxalic acid were evaluated for the interrelationship of ambient pH, buffering capacity added to media, growth, and generation of extracellular proteases and ammonia. Wild-type and acid-overproducing mutan...
