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)

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...

Single-nucleotide polymorphism discovery in Leptographium longiclavatum, a mountain pine beetle-associated symbiotic fungus, using whole-genome resequencing

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...

The mountain pine beetle (Dendroctonus ponderosae Hopkins) (Coleoptera: Curculionidae) is a significant destructive force in the pine forests of western Canada and has the capacity to spread east into a novel host tree species, jack pine (Pinaceae). New populations have been documented in central...

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...

Spatial genetic structure of a symbiotic beetle-fungal system: Toward multi-taxa integrated landscape genetics
Download2011-01-01
Sperling, Felix A. H., Hamelin, Richard C., Murray, Brent W., James, Patrick M. A., Coltman, Dave W.
Spatial patterns of genetic variation in interacting species can identify shared features that are important to gene flow and can elucidate co-evolutionary relationships. We assessed concordance in spatial genetic variation between the mountain pine beetle (Dendroctonus ponderosae) and one of its...

The contribution of genetics and genomics to understanding the ecology of the mountain pine beetle system
Download2019-01-01
Cullingham, Catherine I., Janes, Jasmine K., Hamelin, Richard C., James, Patrick M.A., Murray, Brent W., Sperling, Felix A.H.
Environmental change is altering forest insect dynamics worldwide. As these systems change, they pose significant ecological, social, and economic risk through, for example, the loss of valuable habitat, green space, and timber. Our understanding of such systems is often limited by the complexity...

Unequal recombination and evolution of the mating-type (MAT) loci in the pathogenic fungus Grosmannia clavigera and relatives. G3: Genes, Genomes, Genetics
Download2013-01-01
Hamelin, Richard C., Tsui, Clement K.M., Bohlmann, Jörg, DiGuistini, Scott, Dhillon, Braham, Feau, Nicolas, Wang, Ye
Sexual reproduction in fungi is regulated by the mating-type (MAT) locus where recombination is suppressed. We investigated the evolution of MAT loci in eight fungal species belonging to Grosmannia and Ophiostoma (Sordariomycetes, Ascomycota) that include conifer pathogens and beetle symbionts....
