Human and Plant Fungal Pathogens: The Role of Secondary Metabolites
Secondary metabolites (SM) are small organic molecules produced by various microorganisms (mainly fungi and actinobacteria, among others) through the action of large enzymes like nonribosomal peptide synthetases (NRPS) and polyketide synthases (PKS) or by enzymes like dimethylallyl transferases and prenyltransferases. These special metabolites are in general not essential for growth but are bel...
متن کاملAntagonist actinomycetes metabolites against plant pathogens fungi of agricultural importance
The study was conducted over the years 2012-2013 in order to evaluate the antagonistic effects of the metabolites of actinomycetes against phytopathogenic fungi of agricultural importance. To demonstrate the antagonist activity of antibiosis, bioassays were performed in vitro using the method of wells with cell-free filtrates and the double layer method with chloroform in order to kill living c...
متن کاملPhytotoxic secondary metabolites and peptides produced by plant pathogenic Dothideomycete fungi.
Many necrotrophic plant pathogenic fungi belonging to the class of Dothideomycetes produce phytotoxic metabolites and peptides that are usually required for pathogenicity. Phytotoxins that affect a broad range of plant species are known as non-host-specific toxins (non-HSTs), whereas HSTs affect only a particular plant species or more often genotypes of that species. For pathogens producing HST...
متن کاملA survey of phytotoxic microbial and plant metabolites as potential natural products for pest management.
Phytotoxic microbial metabolites produced by certain phytopathogenic fungi and bacteria, and a group of phytotoxic plant metabolites including Amaryllidacea alkaloids and some derivatives of these compounds were evaluated for algicide, bactericide, insecticide, fungicide, and herbicide activities in order to discover natural compounds for potential use in the management and control of several i...
متن کاملRelative inhibition of insect phenoloxidase by cyclic fungal metabolites from insect and plant pathogens.
The fungal metabolite kojic acid, which is produced by Aspergillus and Penicillium species fungi that may be pathogens of both insects and plants, was a significant inhibitor of phenoloxidase of different representative beetle and caterpillar insect species. Fusaric acid and picolinic acid, produced by Fusarium spp., were also significant inhibitors of phenoloxidase, while dipicolinic acid and ...
