| multigene phylogenies and morphological characterization of five new ophiostoma spp. associated with spruce-infesting bark beetles in china. | ophiostoma spp. (ophiostomatales, ascomycota) are well-known fungi associated with bark beetles (coleoptera: scolytinae). some of these are serious tree pathogens, while the majority is blue-stain agents of timber. in recent years, various bark beetle species have been attacking spruce forests in qinghai province, china, causing significant damage. a preliminary survey was done to explore the diversity of the ophiostomatoid fungal associates of these beetles. the aims of the present study were t ... | 2016 | 27020148 |
| nutritional and pathogenic fungi associated with the pine engraver beetle trigger comparable defenses in scots pine. | conifer bark beetles are often associated with fungal complexes whose components have different ecological roles. some associated species are nutritionally obligate fungi, serving as nourishment to the larvae, whereas others are pathogenic blue-stain fungi known to be involved in the interaction with host defenses. in this study we characterized the local and systemic defense responses of scots pine (pinus sylvestris l.) against ophiostoma brunneo-ciliatum math. (a blue-stain pathogen) and hyalo ... | 2012 | 22718525 |
| use of loop-mediated isothermal amplification for detection of ophiostoma clavatum, the primary blue stain fungus associated with ips acuminatus. | loop-mediated isothermal amplification (lamp) is an alternative amplification technology which is highly sensitive and less time-consuming than conventional pcr-based methods. three lamp assays were developed, two for detection of species of symbiotic blue stain fungi associated with ips acuminatus, a bark beetle infesting scots pine (pinus sylvestris), and an additional assay specific to i. acuminatus itself for use as a control. in common with most bark beetles, i. acuminatus is associated wit ... | 2013 | 23396326 |
| the ophiostoma clavatum species complex: a newly defined group in the ophiostomatales including three novel taxa. | two species of blue-stain fungi with similar morphologies, ophiostoma brunneo-ciliatum and ophiostoma clavatum, are associates of bark beetles infesting pinus spp. in europe. this has raised questions whether they represent distinct taxa. absence of herbarium specimens and contaminated or mistakenly identified cultures of o. brunneo-ciliatum and o. clavatum have accentuated the uncertainty regarding their correct identification. the aim of this study was to reconsider the identity of european is ... | 2016 | 27142088 |
