Molecular Mechanism of Overcoming Host Resistance by the Target of Rapamycin Gene in Leptographium qinlingensis [PDF]

Microorganisms, 2022
Leptographium qinlingensis is a fungal symbiont of the Chinese white pine beetle (Dendroctonus armandi) and a pathogen of the Chinese white pine (Pinus armandii) that must overcome the terpenoid oleoresin defenses of host trees to invade and colonize. L.

Ophiostomatoid fungi synergize attraction of the Eurasian spruce bark beetle, Ips typographus to its aggregation pheromone in field traps [PDF]

Frontiers in Microbiology, 2022
Eurasian spruce bark beetle, Ips typographus is a destructive pest of the Norway spruce (Picea abies). Recent outbreaks in Europe have been attributed to global warming and other anthropogenic impacts.

Population structure of mountain pine beetle symbiont Leptographium longiclavatum and the implication on the multipartite beetle-fungi relationships.

PLoS ONE, 2014
Over 18 million ha of forests have been destroyed in the past decade in Canada by the mountain pine beetle (MPB) and its fungal symbionts. Understanding their population dynamics is critical to improving modeling of beetle epidemics and providing ...

Mycobiota associated with Hylurgops palliatus (Gyll.) on Pinus sylvestris L. in Poland

Acta Societatis Botanicorum Poloniae, 2011
The assemblage and abundance of fungal species associated with Hylurgops palliatus on Pinus sylvestris, were studied in Poland. Fungi were isolated from beetles of H. palliatus and their galleries collected from three populations.

Dose-response modelling uncovers compound-specific inhibitory effects of host defence volatiles on mountain pine beetle fungal symbionts. [PDF]

Pest Manag Sci
Host defence volatiles inhibit mountain pine beetle fungal symbionts in a compound‐ and enantiomer‐specific manner, with distinct dose–response profiles that reveal the multitarget chemical defences of beetle–fungi symbiotes. Abstract BACKGROUND The mountain pine beetle relies on symbiotic fungi to overcome host tree defences, yet these fungi must ...

Establishment of RNA Interference Genetic Transformation System and Functional Analysis of FlbA Gene in Leptographium qinlingensis. [PDF]

Int J Mol Sci, 2023
Leptographium qinlingensis is a pathogenic fungus of Pinus armandii that is epidemic in the Qinling Mountains. However, an effective gene interference strategy is needed to characterize the pathogenic genes in this fungus on a functional level. Using the

Two new species of Ophiostomatales (Sordariomycetes) associated with the bark beetle Dryocoetes alni from Poland [PDF]

MycoKeys, 2020
Bark beetles belonging to the genus Dryocoetes (Coleoptera, Curculionidae, Scolytinae) are known vectors of fungi, such as the pathogenic species Grosmannia dryocoetidis involved in alpine fir (Abies lasiocarpa) mortality.

First Report of <i>Ophiostoma clavatum</i> and <i>Fusarium verticillioides</i> Associated With <i>Ips acuminatus</i>-Infested Scots Pine in Western Ukraine. [PDF]

Plant Environ Interact
This study provides the first record of Ophiostoma clavatum associated with Ips acuminatus in Ukraine, and the first evidence of Fusarium verticillioides coexisting with ophiostomatoid fungi in infested Scots pines. This fungal association may contribute to the decline of Scots pine stands.

Taxonomy and phylogeny of the Leptographium olivaceum complex (Ophiostomatales, Ascomycota), including descriptions of six new species from China and Europe [PDF]

MycoKeys, 2019
The Leptographium olivacea complex encompasses species in the broadly defined genus Leptographium (Ophiostomatales, Ascomycota) that are generally characterized by synnematous conidiophores. Most species of the complex are associates of conifer-infesting
