Cerato-ulmin, a toxin involved in Dutch elm disease, is a fungal hydrophobin.
Hydrophobins are components of microbial cell walls that contribute tocell surface hydrophobicity. The hydrophobic nature of the surfaces of many microbes, both prokaryotic and eukaryotic, is important to such processes as adhesion of pathogens to host structures and dispersa1 of aerial spores (Beever and Dempsey, 1978; Doyle and Rosenberg, 1990; Stringer et al., 1991). A class of peptide hydro...
متن کاملStudy on two species of Ophiostoma in relation with Dutch elm disease in Iran
An investigation was carried out in some areas of Golestan Province including: Loveh forest, Soosara, Daland forest park, Tooskestan; Gilan Province including Siahkal and Asalem forests; Arasbaran and landscape of urban trees during 1999–2007. In this investigation, based on some morphological, physiological and molecular characteristics and also comparison with standard isolates two species Op...
متن کاملthe involvement of cerato-ulmin toxin on pathogenicity and survive of ophiostoma ulmi and o. novo-ulmi fungi, causal agents of dutch elm disease
cerato-ulmin is the most important toxin of fungal causal agents of dutch elm disease and its content is one of the most important factors to distinguish two species ophiostoma ulmi and o. novo-ulmi. with attention to the ophiostoma novo-ulmi is more pathogenicity than o. ulmi, this research was carried out to discuss the role of cerato-ulmin on pathogenicity of causal agent using measurement o...
متن کاملPhylogeny and taxonomy of the Ophiostoma piceae complex and the Dutch elm disease fungi
The Ophiostoma piceae complex forms a monophyletic group of insect-dispersed pyrenomycetes with synnemata (Pesotum) and micronematous (Sporothrix) synanamorphs. Other species of Ophiostoma outside of the 0. piceae complex that form synnemata lack the Sporothrix state. The nine recognized species within the 0. piceae complex are delimited by synnema morphology, growth rate at 32 C, mating reacti...
متن کاملFunctional Annotation of the Ophiostoma novo-ulmi Genome: Insights into the Phytopathogenicity of the Fungal Agent of Dutch Elm Disease
The ascomycete fungus Ophiostoma novo-ulmi is responsible for the pandemic of Dutch elm disease that has been ravaging Europe and North America for 50 years. We proceeded to annotate the genome of the O. novo-ulmi strain H327 that was sequenced in 2012. The 31.784-Mb nuclear genome (50.1% GC) is organized into 8 chromosomes containing a total of 8,640 protein-coding genes that we validated with...
