Functions of mountain pine beetle cytochromes P450 CYP6DJ1, CYP6BW1 and CYP6BW3 in the oxidation of pine monoterpenes and diterpene resin acids
Download2019-01-01
Chiu, Christine C., Keeling, Christopher I., Henderson, Hannah M., Bohlmann, Joerg
The mountain pine beetle (MPB; Dendroctonus ponderosae) is a forest insect pest that attacks several different pine (Pinus) species in its native range of distribution in western North America. MPB are exposed for most of their life cycle to the chemical defenses of their hosts. These defenses...

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...

Global and comparative proteomic profiling of overwintering and developing mountain pine beetle, Dendroctonus ponderosae (Coleoptera: Curculionidae), larvae
Download2012
Keeling, Christopher I., Huber, Dezene P.W., Pitt, Caitlin, Fraser, Jordie D., Bohlmann, Jörg, Bonnett, Tiffany R., Robert, Jeanne A.
Background Mountain pine beetles, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae), are native to western North America, but have recently begun to expand their range across the Canadian Rocky Mountains. The requirement for larvae to withstand extremely cold winter temperatures and...

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...

Identification of genes and gene expression associated with dispersal capacity in the mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae)
Download2021-07-01
Shegelski, Victor A., Evenden, Maya L., Huber, Dezene P. W., Sperling, Felix A. H.
Dispersal flights by the mountain pine beetle have allowed range expansion and major damage to pine stands in western Canada. We asked what the genetic and transcriptional basis of mountain pine beetle dispersal capacity is. Using flight mills, RNA-seq and a targeted association study, we...

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...

Cullingham, Catherine I., Sperling, Felix A. H., Coltman, David W., Roe, Amanda D.
Irruptive forest insect pests cause considerable ecological and economic damage, and their outbreaks have been increasing in frequency and severity. We use a phylogeographic approach to understand the location and progression of an outbreak by the MPB (Dendroctonus ponderosae Hopkins), an...

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....

Repurposing population genetics data to discern genomic architecture: A case study of linkage cohort detection in mountain pine beetle (Dendroctonus ponderosae)
Download2019-01-01
Trevoy, Stephen A.L., Janes, Jasmine K., Muirhead, Kevin, Sperling, Felix A. H.
Genetic surveys of the population structure of species can be used as resources for exploring their genomic architecture. By adjusting filtering assumptions, genomewide single-nucleotide polymorphism (SNP) datasets can be reused to give new insights into the genetic basis of divergence and...

Horianopoulos, Linda C., Boone, Celia K., Samarasekera, Gayathri, Kandola, Gurkirat K., Murray, Brent W.
The mountain pine beetle (Dendroctonus ponderosae) is an insect native to western North America; however, its geographical range has recently expanded north in BC and east into Alberta. To understand the population structure in the areas of expansion, 16 gene‐linked microsatellites were screened...
