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...

Worldwide, forest pathogens are a major cause of forest disturbances and can impact economic revenues and endanger host species and their ecosystems. Genomics represents one of the most promising avenues to better understand and prevent forest disease epidemics. Pathogen genome characterization...

De novo genome sequence assembly of a filamentous fungus using Sanger, 454 and Illumina sequence data

Docking, Roderick T., Mardis, Elaine, Hamelin, Richard C., Jones, Steven J. M., Marra, Marco A., Seidel, Michael, Chan, Simon K., Breuil, Colette, Liao, Nancy Y., Birol, Inanc, Robertson, Gordon, Holt, Robert A., Platt, Darren, Bohlmann, Jörg, DiGuistini, Scott, Hirst, Martin
Sequencing-by-synthesis technologies can reduce the cost of generating de novo genome assemblies. We report a method for assembling draft genome sequences of eukaryotic organisms that integrates sequence information from different sources, and demonstrate its effectiveness by assembling an...

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...

Genetic and genomic evidence of niche partitioning and adaptive radiation in mountain pine beetle fungal symbionts

Ojeda Alayon, Dario I., Tsui, Clement K.M., Feau, Nicolas, Capron, Arnaud, Dhillon, Braham, Zhang, Yiyuan, Massoumi Alamouti, Sepideh, Boon, Celia K., Carroll, Allan L., Cooke, Janice E.K., Roe, Amanda D., Sperling, Felix A.H., Hamelin, Richard C.
Bark beetles form multipartite symbiotic associations with blue stain fungi (Ophiostomatales, Ascomycota). These symbionts play an important role during the beetle’s life cycle by providing nutritional supplementation, overcoming tree defenses and modifying host tissues to favor...

Wittische, Julian, Janes, Jasmine K., James, Patrick M. A.
The current mountain pine beetle (MPB; Dendroctonus ponderosae Hopkins, 1902) outbreak has reached more than 25 million hectares of forests in North America, affecting pine species throughout the region and substantially changing landscapes. However, landscape features that enhance or limit...

Molecular assays to detect the presence and viability of Phytophthora ramorum and Grosmannia clavigera
Download2020-02-01
Wong, Barbara, Leal, Isabel, Feau, Nicolas, Dale, Angela, Uzunovic, Adnan, Hamelin, Richard C.
Wood and wood products can harbor microorganisms that can raise phytosanitary concerns in countries importing or exporting these products. To evaluate the efficacy of wood treatment on the survival of microorganisms of phytosanitary concern the method of choice is to grow microbes in petri dishes...

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....

Single-nucleotide polymorphism discovery in Leptographium longiclavatum, a mountain pine beetle-associated symbiotic fungus, using whole-genome resequencing
Download2014-01-01
Ojeda, Dario I., Dhillon, Braham, Tsui, Clement K. M., Hamelin, Richard C.
Single-nucleotide polymorphisms (SNPs) are rapidly becoming the standard markers in population genomics studies; however, their use in nonmodel organisms is limited due to the lack of cost-effective approaches to uncover genome-wide variation, and the large number of individuals needed in the...

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...
