Chemotypic variations of lodgepole pine affect mountain pine beetle behaviour and growth of its symbiotic fungus
DownloadSpring 2020
Plants generally show large chemotypic variations in susceptibility to phytophagous insects and pathogens. Plant chemical defenses, or secondary compounds, are important components of plant resistance to pest organisms. Among plants, coniferous trees produce complex oleoresins that contain toxic...

Comparative genomics of the chitinase gene family in lodgepole and jack pines: contrasting responses to biotic threats and landscape level investigation of genetic differentiation.
Download2021-02-01
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...

Comparing lodgepole pine defence responses against mountain pine beetle and Grosmannia clavigera
DownloadSpring 2024
The mountain pine beetle (Dendroctonus ponderosae Hopkins; MPB) is a bark beetle that poses a significant threat to pine species in western North America. This threat is evident in the ongoing MPB epidemic, which has resulted in significant losses of lodgepole pine (Pinus contorta var. latifolia)...

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...

Spatial characteristics of volatile communication in lodgepole pine trees: Evidence of kin recognition and intra-species support
Download2019-11-01
Hussain, Altaf, Rodriquez-Ramos, Jean C., Erbilgin, Nadir
Plant interactions using volatile organic compounds, particularly in the context of kin recognition have received considerable attention in recent years, but several discrepancies and conflicting results have restricted our understanding. We propose that some of these discrepancies in literature...

Transcriptomic analyses of Pinus contorta responses to Grosmannia clavigera under contrasting levels of nitrogen availability
DownloadSpring 2021
In western Canada alone, the current mountain pine beetle (MPB) outbreak has devastated nearly 19 million hectares of pine forest, negatively impacting communities, industries and ecosystems. Reforestation efforts can benefit from a deeper understanding of the impact of nitrogen (N)-based...
