| The expression of the cerato-platanin gene is related to hyphal growth and chlamydospores formation in Ceratocystis platani. | Cerato-platanin (CP) is a protein produced by Ceratocystis platani, the causal agent of canker stain disease of plane trees. CP is the first member of the "cerato-platanin family" and its role as a PAMP (pathogen-associated molecular pattern), inducing defence responses both in host and non-host plants, is established. However, the primary role of CP and its homologues in the fungal life remains unknown. In the present work we investigated the regulation of the cp gene during the in vitro growth ... | 2011 | 22136757 |
| the structure of the elicitor cerato-platanin (cp), the first member of the cp fungal protein family, reveals a double ?ß-barrel fold and carbohydrate binding. | cerato-platanin (cp) is a secretion protein produced by the fungal pathogen ceratocystis platani, the causal agent of the plane canker disease and the first member of the cp family. cp is considered a pathogen-associated molecular pattern because it induces various defense responses in the host, including production of phytoalexins and cell death. although much is known about the properties of cp and related proteins as elicitors of plant defense mechanisms, its biochemical activity and host tar ... | 2011 | 21454637 |
| characterization of ordered aggregates of cerato-platanin and their involvement in fungus-host interactions. | the "cerato-platanin family" consists of fungal-secreted proteins that are involved in various stages of the host-fungus interaction and act as phytotoxins, elicitors of defense responses and allergens. cerato-platanin (cp) is a moderately hydrophobic protein secreted and localized in the cell wall of ceratocystis platani, the causal agent of a severe disease of platanus. these properties make cp like the hydrophobins: these are self-assembling proteins that form a surface coating which is invol ... | 2009 | 19631724 |
| new proteins orthologous to cerato-platanin in various ceratocystis species and the purification and characterization of cerato-populin from ceratocystis populicola. | natural variants of cerato-platanin (cp), a pathogen associated molecular pattern (pamp) protein produced by ceratocystis platani (the causal agent of the plane canker stain), have been found to be produced by other four species of the genus ceratocystis, including five clones of ceratocystis fimbriata isolated from different hosts. all these fungal strains were known to be pathogenic to plants with considerable importance in agriculture, forestry, and as ornamental plants. the putative prematur ... | 2009 | 19387635 |
| epl1, the major secreted protein of hypocrea atroviridis on glucose, is a member of a strongly conserved protein family comprising plant defense response elicitors. | we used a proteomic approach to identify constitutively formed extracellular proteins of hypocrea atroviridis (trichoderma atroviride), a known biocontrol agent. the fungus was cultivated on glucose and the secretome was examined by two-dimensional gel electrophoresis. the two predominant spots were identified by maldi ms utilizing peptide mass fingerprints and amino acid sequence tags obtained by postsource decay and/or high-energy collision-induced dissociation (ms/ms) experiments, and turned ... | 2006 | 16939625 |
| cerato-platanin, a phytotoxic protein from ceratocystis fimbriata: expression in pichia pastoris, purification and characterization. | cerato-platanin (cp) is a phytotoxic protein secreted by the ascomycete ceratocystis fimbriata f.sp. platani. this ascomycete causes canker stain which is a severe disease with a high incidence in the european platanus acerifolia. cp probably plays a role in the disease, eliciting defence-related responses in the host plants. cp is a 120 amino acid protein, containing 40% hydrophobic residues and two s-s bridges. in the embl data bank cp is the first member of a new fungal protein family known a ... | 2006 | 16931046 |
| intersterility, morphology and taxonomy of ceratocystis fimbriata on sweet potato, cacao and sycamore. | ceratocystis fimbriata is a large, diverse complex of species that cause wilt-type diseases of many economically important plants. previous studies have shown that isolates in three monophyletic lineages within the latin american clade of c. fimbriata are host-specialized to cacao (theobroma cacao), sweet potato (ipomoea batatas) and sycamore (platanus spp.), respectively. we paired testers of opposite mating type from isolates of these lineages to find intersterility groups. two intersterility ... | 2005 | 16389957 |
| cerato-platanin protein is located in the cell walls of ascospores, conidia and hyphae of ceratocystis fimbriata f. sp. platani. | cerato-platanin (cp), a protein of about 12.4 kda from ceratocystis fimbriata f. sp. platani (cfp), accumulated in the mycelium and was located in the cell walls of cfp ascospores, hyphae and conidia suggesting that this protein had a role in forming the fungal cell wall apart from the already known fact that it is secreted early in culture and elicits phytoalexin synthesis and/or plant cell death. the finding was obtained with three immunological techniques: a quantitative elisa which determine ... | 2004 | 15063505 |
| purification, characterization, and amino acid sequence of cerato-platanin, a new phytotoxic protein from ceratocystis fimbriata f. sp. platani. | a new phytotoxic protein (cerato-platanin) of about 12.4 kda has been identified in culture filtrates of the ascomycete ceratocystis fimbriata f. sp. platani, the causal agent of canker stain disease. the toxicity of the pure protein was bioassayed by detecting the inducing necrosis in tobacco leaves. the pure protein also elicited host synthesis of fluorescent substances in tobacco and plane (platanus acerifolia) leaves. we purified the protein from culture medium to homogeneity. its complete a ... | 1999 | 10455173 |
