Phytotoxic 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 کاملBioactivity of secondary metabolites and thallus extracts from lichen fungi
Fungal secondary compounds and total extracts are known to affect growth of bacteria, fungi, and plants. This study tested the effects of purified compounds and total extracts from three lichens on the growth of two plant pathogens, Ophiostoma novo-ulmi ssp. americana and Sclerotinia sclerotiorum. Usnic acid showed no reduction in relative growth rates (RGR), whereas vulpinic acid reduced RGR f...
متن کاملNovel Secondary Metabolites from Endophytic Marine-derived Fungi
The marine-derived fungus Stachylidium sp. was isolated from the sponge Callyspongia cf. C. flammea. Chemical investigation of the bioactive fungal extract led to the isolation of the novel phthalimidine derivatives marilines A D (1-4). The absolute configuration of the enantiomeric compounds 1 and 2 was assigned by means of theoretical Circular Dichroism calculations. The skeleton of marilines...
متن کاملMarine Fungi as a Source of Secondary Metabolites of Antibiotics
Marine fungi have been shown to be tremendous sources for new and biologically active secondary metabolites which are reflected by the increasing number of published literature dealing with compounds from this group of fungi. As a result to these efforts, more than a hundred secondary metabolites from marine fungi have been described. The mycobiota of the coastal water were collected from five ...
متن کاملInduced plant secondary metabolites for phytopatogenic fungi control: a review
Pathogenic fungi constitute one of the main infectious agents in plants, causing alterations during developmental stages including post-harvest. Phytopathogenic fungi are controlled by synthetic fungicides; however, the use of these is progressively restricted due to both, the harmful effects of pesticides on the environment and human health and the appearance of highly resistant fungal strains...
