Inter- and Intra-Continental Genetic Variation in the Generalist Conifer Wood Saprobic Fungus Phlebiopsis gigantea

Physiological and molecular analysis of the interaction between the conifer pathogen,Heterobasidion annosum s.l. and Phlebiopsis gigantea

Prophylactic stump treatment with Phlebiopsis gigantea has been used for a long time in the biological control of the conifer pathogen, Heterobasidion annosum sensu lato. However, the mechanisms underlying the biocontrol process are poorly understood. A total of 64 isolates of P. gigantea from different geographical regions were screened for fungal traits (growth rate, enzyme production, wood d...

The Biocontrol Agent Phlebiopsis gigantea: Efficacy and Impacts on the Stump Bacterial Biota and Conifer tree Defences

Inter- and intra-specific genetic variation in Fusarium.

Genetic variation occurs at all levels across the genus Fusarium. In some cases such variation has been used to define species, and in others to describe populations or lineages. When amplified fragment length polymorphisms (AFLPs) are evaluated, strains in different species usually share at least 60% of the fragments and those in different species 40% of the fragments, or less, with isolates s...

Analysis of the Phlebiopsis gigantea Genome, Transcriptome and Secretome Provides Insight into Its Pioneer Colonization Strategies of Wood

Collectively classified as white-rot fungi, certain basidiomycetes efficiently degrade the major structural polymers of wood cell walls. A small subset of these Agaricomycetes, exemplified by Phlebiopsis gigantea, is capable of colonizing freshly exposed conifer sapwood despite its high content of extractives, which retards the establishment of other fungal species. The mechanism(s) by which P....

Purification by Immunoaffinity Chromatography, Characterization, and Structural Analysis of a Thermostable Pyranose Oxidase from the White Rot Fungus Phlebiopsis gigantea.

A moderately thermostable pyranose oxidase (PROD) was purified to apparent homogeneity with a yield of 71% from mycelium extracts of the white rot fungus Phlebiopsis gigantea by an efficient three-step procedure that included heat treatment, immunoaffinity chromatography, and gel filtration on Superdex 200. PROD of P. gigantea is a glycoprotein with a pI between pH 5.3 and 5.7. The relative mol...
