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....

Adaptive and neutral markers both show continent-wide population structure of mountain pine beetle (Dendroctonus ponderosae)

Sperling, Felix A. H., Murray, Brent W., Batista, Philip D., Janes, Jasmine K., Boone, Celia K.
Assessments of population genetic structure and demographic history have traditionally been based on neutral markers while explicitly excluding adaptive markers. In this study, we compared the utility of putatively adaptive and neutral single-nucleotide polymorphisms (SNPs) for inferring mountain...

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...

Chemical similarity between historical and novel host plants promotes range and host expansion of the mountain pine beetle in a naïve host ecosystem
Download2013-01-01
Evenden, Maya, Shan, Bin, Ma, Cary, Najar, Ahmed, Erbilgin, Nadir, Whitehouse, Caroline
Host plant secondary chemistry can have cascading impacts on host and range expansion of herbivorous insect populations. We investigated the role of host secondary compounds on pheromone production by themountain pine beetle (Dendroctonus ponderosae) (MPB) and beetle attraction in response to a...

Gene discovery for enzymes involved in limonene modification or utilization by the mountain pine beetle-associated pathogen Grosmannia clavigera
Download2014-01-01
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...

Influence of water deficit on the molecular responses of Pinus contorta × Pinus banksiana mature trees to infection by the mountain pine beetle fungal associate, Grosmannia clavigera

Kayal, Walid El, Cooke, Barry J., Linsky, Jean, Arango-Velez, Adriana, Galindo González, Leonardo M., Cooke, Janice E.K., Meents, Miranda J., Lusebrink, Inka
Conifers exhibit a number of constitutive and induced mechanisms to defend against attack by pests and pathogens such as mountain pine beetle (Dendroctonus ponderosae Hopkins) and their fungal associates. Ecological studies have demonstrated that stressed trees are more susceptible to attack by...

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...

Rapid monoterpene induction promotes the susceptibility of a novel host pine to mountain pine beetle colonization but not to beetle-vectored fungi
Download2017-12-01
Cale, Jonathan A, Muskens, Marlena, Najar, Ahmed, Ishangulyyvena, Guncha, Hussain, Altaf, Kanekar, Sanat S, Klutsch, Jennifer G, Taft, Spencer, Erbilgin, Nadir
Chemical induction can drive tree susceptibility to and host range expansions of attacking insects and fungi. Recently, mountain pine beetle (Dendroctonus ponderosae Hopkins; MPB) has expanded its host range from its historic host lodgepole pine (Pinus contorta var. latifolia Douglas ex Loudon)...

Burns, Ian, James, Patrick M.A., Coltman, David W., Cullingham, Catherine I.
In north-central Alberta, lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia) and jack pine (Pinus banksiana Lamb.) form a mosaic hybrid zone, the spatial extent of which remains poorly defined. We sought to refine the genetic and geographic distribution of this hybrid zone in western...
