A species-diagnostic SNP panel for discriminating lodgepole pine, jack pine, and their interspecific hybrids
Download2013-01-01
Dang, S. , Cullingham, Catherine I. , Cooke, Janice E. K., Coltman, David W.
Accurate stock identification is important for forest management, yet this can be a challenge for tree species that hybridize naturally. Species discriminating molecular markers provide a means to identify stock with high accuracy. In Canada, lodgepole pine (Pinus contorta Dougl. ex Loud. var....

Characterizing the physical and genetic structure of the lodgepole pine × jack pine hybrid zone: mosaic structure and differential introgression
Download2012-01-01
Coltman, David W., James, Patrick M. A., Cullingham,Catherine I., Cooke, Janice E. K.
Understanding the physical and genetic structure of hybrid zones can illuminate factors affecting their formation and stability. In north-central Alberta, lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia) and jack pine (Pinus banksiana Lamb) form a complex and poorly defined hybrid...

Comparative genomics of the chitinase gene family in lodgepole and jack pines: contrasting responses to biotic threats and landscape level investigation of genetic differentiation.

Peery, Rhiannon M., McAllister, Chandra H., Cullingham, Catherine I., Mahon, Elizabeth L., Arango-Velez, Adriana, Cooke, Janice E. K.
The sister species, lodgepole pine (Pinus contorta var. latifolia Engelm.) and jack pine (Pinus banksiana Lamb), face pressures from a multitude of biotic agents, including mountain pine beetle (Dendroctonus ponderosae Hopkins, 1902) and their pathogenic fungal associates (e.g., Grosmannia...

Disentangling detoxification: Gene expression analysis of feeding mountain pine beetle illuminates molecular-level host chemical defense detoxification mechanisms
Download2013-01-01
Bohlmann, Jörg, Bonnett, Tiffany R., Pitt, Caitlin, Keeling, Christopher I., Yuen, Macaire M. S., Huber, Dezene P. W., Robert, Jeanne A.
The mountain pine beetle, Dendroctonus ponderosae, is a native species of bark beetle (Coleoptera: Curculionidae) that caused unprecedented damage to the pine forests of British Columbia and other parts of western North America and is currently expanding its range into the boreal forests of...

Effect of water stress and plant defense stimulation on monoterpene emission from a historical and a new pine host of the mountain pine beetle
Download2011-01-01
Cooke, Janice E. K., Blanchet, F. Guillaume, Lusebrink, Inka, Erbilgin, Nadir, Evenden, Maya L.
The mountain pine beetle (Dendroctonus ponderosae, MPB) has killed millions of lodgepole pine (Pinus contorta) trees in Western Canada and recent range expansion has resulted in attack of jack pine (Pinus banksiana) in Alberta. Establishment of MPB in the Boreal forest will require use of jack...

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 expression analysis of overwintering mountain pine beetle larvae suggests multiple systems involved in overwintering stress, cold hardiness, and preparation for spring development
Download2016
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...

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...

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...
