TLDR
Cerato-platanin 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.Abstract:
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 determines the amount of CP in the mycelium, an immunofluorescence assay, and immunogold labelling to define the exact localization of CP in the Cfp cells.read more

Sm1, a proteinaceous elicitor secreted by the biocontrol fungus Trichoderma virens induces plant defense responses and systemic resistance.
TL;DR: Gene expression analysis revealed that SM1 is expressed throughout fungal development under different nutrient conditions and in the presence of a host plant, indicating that Sm1 is involved in the induction of resistance by Trichoderma spp.

TL;DR: Plant bioassays and functional genomics data indicate that T. virens is able to effectively activate systemic disease protection in maize and that the functional Sm1 elicitor is required for this activity.

Small proteins of plant-pathogenic fungi secreted during host colonization.
TL;DR: In this paper, small proteins secreted by plant pathogenic fungi in their hosts have been implicated in disease symptom development as well as in R-gene mediated disease resistance, showing that this class of proteins shows very limited phylogenetic distribution, possibly due to accelerated evolution stimulated by plant-pathogen arms races.

BcSpl1, a cerato-platanin family protein, contributes to Botrytis cinerea virulence and elicits the hypersensitive response in the host
TL;DR: The BcSpl1-treated plant tissues showed symptoms of the hypersensitive response such as induction of reactive oxygen species, electrolyte leakage, cytoplasm shrinkage, and cell autofluorescence, as well as the induction of defense genes considered to be markers ofThe hyperssensitive response.

TasHyd1, a new hydrophobin gene from the biocontrol agent Trichoderma asperellum, is involved in plant root colonization
Ada Viterbo,Ilan Chet +1 more
TL;DR: TasHyd1 deletion mutants had no significant reduction in in vitro mycoparasitic activity but were altered in their wettability and were severely impaired in root attachment and colonization, indicating that the protein is a new hydrophobin that contributes to Trichoderma interaction with the plant.

Hydrophobins: Multipurpose Proteins
TL;DR: Class I and class II hydrophobins are small secreted fungal proteins that play a role in a broad range of processes in the growth and development of filamentous fungi.

Hydrophobins: Proteins that Change the Nature of the Fungal Surface
TL;DR: Hydrophobins were discovered while searching for genes expressed during emergent growth in Schizophyllum commune, and are a novel class of small secreted cysteine-rich proteins of fungi that assemble into amphipathic films when confronted with hydrophilichydrophobic interfaces.

MPG1 encodes a fungal hydrophobin involved in surface interactions during infection-related development of Magnaporthe grisea
TL;DR: It is shown that MPG1 is necessary for infection-related development of Magnaporthe grisea on rice leaves and for full pathogenicity toward susceptible rice cultivars, and a 15-kD secreted protein with characteristics that establish it as a class I hydrophobin is identified.
