Diversity of fungi associated with the mountain pine beetle, Dendroctonus ponderosae and infested lodgepole pines in British Columbia
The mountain pine beetle (Dendroctonus ponderosae), one of the most destructive bark beetles, has damaged large areas of lodgepole pine forests in British Columbia (Canada). It has been suggested…

It is established that Gc is heterothallic, and evidence for repeat-induced point mutation is reported, and insights are reported into how Gc tolerates conifer-defense chemicals, including oleoresin terpenoids, as they colonize a host tree.
Enumeration of petroleum-degrading marine and estuarine microorganisms by the most probable number method.
All strains of oil-degrading microorganisms examined in this study were lipolytic, but the converse was not always true, and the oil-amended agar permits growth of organisms which do not degrade crude oil.
The genome and transcriptome of the pine saprophyte Ophiostoma piceae, and a comparison with the bark beetle-associated pine pathogen Grosmannia clavigera
This work makes available the second annotated genome of a softwood ophiostomatoid fungus, and suggests that O. piceae’s tolerance to terpenes may be due in part to these chemicals being removed from the cells by an ABC transporter that is highly induced by ter penes.
Leptographium longiclavatum sp. nov., a new species associated with the mountain pine beetle, Dendroctonus ponderosae.
Comparisons showed that this fungus is distinct from all the other Leptographium species described in the literature, and especially from O. clavigerum, and is described as L. longiclavatum sp.
Pathogenicity of Leptographium longiclavatum associated with Dendroctonus ponderosae to Pinus contorta
Both O. clavigerum and L. longiclavatum generated significantly longer necrotic lesions in the phloem and more occlusions in the sapwood than in the agar controls, and the sap wood colonized by both fungi had a reduced moisture co...
Ophiostomatoid and basidiomycetous fungi associated with green, red, and grey lodgepole pines after mountain pine beetle (Dendroctonus ponderosae) infestation
The mountain pine beetle (MPB) is a major concern for lodgepole pine (Pinus contorta var. latifolia Engelm.) forests in British Columbia, Canada. MPB and the ophiostomatoid staining fungi for which...
Comparison of the 3,5-dinitrosalicylic acid and Nelson―Somogyi methods of assaying for reducing sugars and determining cellulase activity
De novo genome sequence assembly of a filamentous fungus using Sanger, 454 and Illumina sequence data
A method for assembling draft genome sequences of eukaryotic organisms that integrates sequence information from different sources is reported, and its effectiveness is demonstrated by assembling an approximately 32.5 Mb draft genome sequence for the forest pathogen Grosmannia clavigera, an ascomycete fungus.
