Fungal Elicitors of Invertebrate Cell Defense System
1988Arthropods, lacking the true immunoglobulin and T-type lymphocyte system characteristic of vertebrates, possess an array of defense systems which protect them against fungal attack. Whether common defense mechanisms are possessed by the arthropod group is unclear. The defensive needs of this diverse group of organisms are extremely variable.

Studies on the structure and elicitor activity of fungal glucans
Canadian Journal of Botany, 1980Neutral sugar compositions of materials released from isolated mycelial walls of race 1 and race 2 of Fusarium oxysporum f. sp. lycopersici and Fusarium oxysporum f. sp. cubense were similar (5% ribose, 52% mannose, 28% galactose, 15% glucose). High molecular weight glucans were isolated by ion-exchange chromatography from the cell wall extracts of ...

Influence of fungal elicitors on biosynthesis of natamycin by Streptomyces natalensis HW-2
Applied Microbiology and Biotechnology, 2013To investigate the effect of fungal elicitors on biosynthesis of natamycin in the cultures of Streptomyces natalensis HW-2, the biomass and filtrate of the broth from Aspergillus niger AS 3.6472, Penicillium chrysogenum AS 3.5163, A. oryzae AS 3.2068, and Saccharomyces cerevisiae AS 2.2081 were used to induce natamycin production in S. natalensis HW-2.

Fungal elicitors of the phytoalexin response in higher plants
Naturwissenschaften, 1981Several types of fungal molecules including cell wall polysaccharides, polypeptides, glycoproteins and lipid molecules have been found to serve as elicitors of phytoalexins in higher plants. Recent work has shown that an extracellular enzyme, endopolygalacturonase, from culture filtrates of the fungusRhizopus stolonifer elicits the biosynthesis of an ...

The enzyme squalene synthase (SS) represents the first commitment of carbon from the general isoprenoid pathway toward sterol biosynthesis and is a potential point for regulation of sterol biosynthesis. The isolation and characterization of tobacco (Nicotiana tabacum) squalene synthase (TSS) cDNA and genomic DNA clones, as well as determination of the ...

Specific Recognition of a Fungal Oligopeptide Elicitor by Parsley Cells
1994Cultured parsley (Petroselinum crispum) cells or protoplasts respond to treatment with a crude cell wall preparation from the soybean pathogen Phytophthora megasperma f.sp. glycinea (Pmg elicitor) with the transcriptional activation of the same set of defense-related genes as are activated in parsley leaves upon infection with fungal spores [1-4].

Suspension cultures of Panax ginseng C.A. Meyer (Araliaceae) were treated with either an elicitor preparation from the culture broth of the phytopathogenic hyphomycete Botrytis cinerea or a yeast elicitor preparation, and the accumulation of a new compound, which was not detected in non-elicited cultures, was observed.

Enhanced resistance to foliar fungal pathogens in carrot by application of elicitors
Annals of Applied Biology, 2009AbstractTreatment of greenhouse‐grown carrot plants with salicylic acid (SA) (100 μm), chitosan (0.02%) and the nutrient‐chelate product Alexin (1%) followed 10 h later by inoculation with the necrotrophic fungal pathogens Alternaria radicina and Botrytis cinerea significantly reduced disease development 10 days after inoculation (d.a.i.) compared with

The transcription rates of numerous plant genes have previously been shown to be strongly affected by pathogen infection or elicitor treatment. Here we estimate the extent and complexity of this response by analyzing the patterns of mRNA induction in fungal elicitor-treated parsley cells (Petroselinum crispum) for several representatives from various ...

Induction of Enzymes of Phytoalexin Synthesis in Soybean Cells by Fungal Elicitor
1985Higher plants have aquired effective defence mechanisms during evolution, which secure their survival in the presence of a large variety of infective microorganisms. Resistance mechanisms of plants are expressed at different levels in host-parasite interactions including preformed physical and chemical defence barriers as well as defences triggered by ...
