The Ophiostoma piceae complex in the Southern Hemisphere: a phylogenetic study
Mycological Research, 2003The Ophiostoma piceae species complex incorporates several economically important species, including serious tree pathogens and agents of bluestain. The species in the complex are morphologically similar, but can be distinguished from each other based on morphology, biology, mating type studies and molecular data.

Abstract Vegetative growth as a means of differentiating Ophiostoma piceae from Ophiostoma querci. Isolates of Ophiostoma piceae from spruce (Picea abies) and O. querci from oak (Quercus robur) showed distinct differences in vegetative growth of cultures at a wide range of temperatures.

Assessing RNAi frequency and efficiency in Ophiostoma floccosum and O. piceae
Fungal Genetics and Biology, 2006Ophiostoma species are an economically important group of saprophytic and pathogenic fungi that grow in trees or wood. Ophiostoma like O. piceae and O. floccosum produce melanin, a pigment that stains lumber and logs. We used such species as model organisms for characterizing the molecular mechanisms in fungal melanin production.

Production, isolation and characterization of a sterol esterase from Ophiostoma piceae
Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2002We studied extracellular sterol esterase production by the ascomycete Ophiostoma piceae in liquid culture. Esterase activity was found in low levels in glucose medium but it was strongly induced by olive oil. An esterase was purified from the 0.5% olive oil-supplemented cultures using ultrafiltration followed by a single chromatographic step on a ...

Genomic fingerprinting supports the separation of Ophiostoma piceae into two species
Mycological Research, 1995Fourteen isolates of Ophiostoma piceae from diverse regions and hosts across Europe and North America, which had been assigned to the OPC (conifer) and OPH (hardwood) species groups on the basis of their reproductive isolation, were compared by molecular methods.

Production of lipolytic enzymes in batch cultures of Ophiostoma piceae
Journal of Chemical Technology & Biotechnology, 2001AbstractAfter an extensive fungal screening, an Ophiostoma piceae strain was selected for its ability to produce high concentrations of lipase and esterase to remove pitch components of wood pulp. Optimal conditions for growth and enzyme production were established first in shaken flasks.

Ophiostoma setosum is described as a new species commonly associated with exposed sapwood of Tsuga heterophylla in western North America. It is characterized by the production of a typical ophiostomatoid teleomorph, a Pesotum anamorph with conspicuous, dark seta-like hyphae on the synnema stipes and apices, and a Sporothrix mycelial anamorph with ...

Temperature-growth responses distinguish the OPC and OPH sibling species within ‘Ophiostoma piceae’
Mycological Research, 1993The temperature-growth relationships of a range of isolates representing the recently identified OPC and OPH sibling species within Ophiostoma piceae were studied. Most OPC isolates grew significantly faster than OPH isolates on 2% Oxoid malt extract agar (MEA) between 17·5 and 27·5 °C, but between 27·5° and 30° growth rates of all OPC isolates ...

Functions of a proteinase secreted by the sap-staining fungus Ophiostoma piceae
2009Fungal colonisation that discolours wood decreases its market value, reducing profits on Canadian lumber products. Disrupting key enzymes involved in fungal metabolism could be a way of preventing such wood-inhabiting fungi from colonising lumber.
