Fine-scale genetic diversity and relatedness in fungi associated with the mountain pine beetle
Download2019-01-01
Tsui, Clement K. M., Beauseigle, Stephanie, Ojeda Alayon, Dario I., Rice, Adrianne V., Cooke, Janice E. K., Sperling, Felix A. H., Roe, Amanda D., Hamelin, Richard C.
The mountain pine beetle (MPB; Dendroctonus ponderosae Hopkins, 1902) forms beneficial symbiotic associations with fungi. Here we explored the fine-scale spatial genetic structure of three of those fungi using single nucleotide polymorphism. We found that single mated pairs of beetles carry not...

Gene discovery for enzymes involved in limonene modification or utilization by the mountain pine beetle-associated pathogen Grosmannia clavigera

Lah, Ljerka, Wang, Ye, Breuil, Colette, Madilao, Lina, Bohlmann, Joerg, Lim, Lynette
To successfully colonize and eventually kill pine trees, Grosmannia clavigera (Gs cryptic species), the main fungal pathogen associated with the mountain pine beetle (Dendroctonus ponderosae), has developed multiple mechanisms to overcome host tree chemical defenses, of which terpenoids are a...

Henderson, Hannah, Keeling, Christopher I.Wang, Ye, Docking, Roderick T., Breuil, Colette, Li, Maria, Jones, Steven J. M., Liao, Nancy Y., Hesse-Orce, Uljana, DiGuistini, Scott, Robertson, Gordon, Bohlmann, Jörg, Holt, Robert A.
Background Grosmannia clavigera is a bark beetle-vectored fungal pathogen of pines that causes wood discoloration and may kill trees by disrupting nutrient and water transport. Trees respond to attacks from beetles and associated fungi by releasing terpenoid and phenolic defense compounds. It is...

Gene expression analysis of overwintering mountain pine beetle larvae suggests multiple systems involved in overwintering stress, cold hardiness, and preparation for spring development

Robert, Jeanne A., Bonnett, Tiffany R., Pitt, Caitlin, Spooner, Luke J., Fraser, Jordan D., Yuen, Macaire M. S., Keeling, Christopher I., Bohlmann, Jorg, Huber, Dezene P. W.
Cold-induced mortality has historically been a key aspect of mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae), population control, but little is known about the molecular basis for cold tolerance in this insect. We used RNA-seq analysis to monitor gene expression...

How the mountain pine beetle (Dendroctonus ponderosae) breached the Canadian Rocky Mountains
Download2014-01-01
Sperling, Felix A. H., Murray, Brent W., Li, Yisu, Coltman, David W., Bohlmann, Joerg, Janes, Jasmine K., Cooke, Janice E. K., Boone, Celia K., Huber, Dezene P.W., Keeling, Christopher I., Yuen, Macaire M. S.
The mountain pine beetle (MPB; Dendroctonus ponderosae Hopkins), a major pine forest pest native to western North America, has extended its range north and eastward during an ongoing outbreak. Determining how the MPB has expanded its range to breach putative barriers, whether physical...

Linking genotype to phenotype to identify genetic variation relating to host susceptibility in the mountain pine beetle system
Download2020-01-01
Cullingham, Catherine I., Peery, Rhiannon M., Fortier, Colleen E., Mahon, Elizabeth L., Cooke, Janice E. K., Coltman, David W.
Identifying genetic variants responsible for phenotypic variation under selective pressure has the potential to enable productive gains in natural resource conservation and management. Despite this potential, identifying adaptive candidate loci is not trivial, and linking genotype to phenotype is...

Population Structure of Mountain Pine Beetle Symbiont Leptographium longiclavatum and the Implication on the Multipartite Beetle-Fungi Relationships
Download2014-01-01
Roe, Amanda D., Farfan, Lina, Cooke, Janice E. K., Hamelin, Richard C., El-Kassaby, Yousry A., Rice, Adrianne V., Tsui, Clement K.
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 potential clues to predict population expansion....

Spatial community structure of mountain pine beetle fungal symbionts across a latitudinal gradient
Download2011
Roe, Amanada D., James, Patrick M. A., Cooke, Janice E. K., Sperling, Felix A. H., Rice, Adrianne V.
Symbiont redundancy in obligate insect–fungal systems is thought to buffer the insect host against symbiont loss and to extend the environmental conditions under which the insect can persist. The mountain pine beetle is associated with at least three well-known and putatively obligate...

Target-specific PCR primers can detect and differentiate ophiostomatoid fungi from microbial communities associated with the mountain pine beetle Dendroctonus ponderosae.

Khadempour, Lily, Alamouti, Sepideh Massoumi, Hamelin, Richard, Bohlmann, Jörg, Breuil, Colette
The aim of this study was to develop DNA probes that could identify the major fungal species associated with mountain pine beetles (MPB). The beetles are closely associated with fungal species that include ophiostomatoid fungi that can be difficult to differentiate morphologically. The most...

Transcriptome resources and functional characterization of monoterpene synthases for two host species of the mountain pine beetle, lodgepole pine (Pinus contorta) and jack pine (Pinus banksiana)

Hall, Dawn E., Arango-Velez, Adriana, Dullat, Harpreet K., Keeling, Christopher I., Breuil, Colette, Liao, Nancy Y., Henderson, Hannah, Bohlmann, Jörg, Cooke, Janice E. K., Quesada, Alfonso L., Jones, Steven J. M., Chan, Simon K., Jancsik, Sharon, Docking, Roderick T., Li, Maria, Yuen, Macaire M. S.
Background The mountain pine beetle (MPB, Dendroctonus ponderosae) epidemic has affected lodgepole pine (Pinus contorta) across an area of more than 18 million hectares of pine forests in western Canada, and is a threat to the boreal jack pine (Pinus banksiana) forest. Defence of pines against...
