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....

Proteomics indicators of the rapidly shifting physiology from whole mountain pine beetle, Dendroctonus ponderosae (Coleoptera: Curculionidae), adults during early host colonization

Bohlmann, Jörg, Pitt, Caitlin, Huber, Dezene P. W. , Bonnett, Tiffany R., Keeling, Christopher I., Robert, Jeanne A.
We developed proteome profiles for host colonizing mountain pine beetle adults, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae). Adult insects were fed in pairs on fresh host lodgepole pine, Pinus contorta Dougl. ex Loud, phloem tissue. The proteomes of fed individuals were monitored...

Disentangling detoxification: Gene expression analysis of feeding mountain pine beetle illuminates molecular-level host chemical defense detoxification mechanisms

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...

Autoregulation of RNA helicase expression in response to temperature stress in Synechocystis spCC 6803
Download2012
Owttrim, George W., Chamot, Danuta, Rosana, Albert R. R.
RNA helicases are ubiquitous enzymes whose modification of RNA secondary structure is known to regulate RNA function. The pathways controlling RNA helicase expression, however, have not been well characterized. Expression of the cyanobacterial RNA helicase, crhR, is regulated in response to...

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...

Functional genomics of mountain pine beetle (Dendroctonus ponderosae) midguts and fat bodies

Keeling, Christopher I., Bearfield, Jeremy C., Blomquist, Gary J., Schlauch, Karen, Tittiger, Claus, Young, Sharon, Aw, Tidiane
Background The mountain pine beetle (Dendroctonus ponderosae) is a significant coniferous forest pest in western North America. It relies on aggregation pheromones to colonize hosts. Its three major pheromone components, trans-verbenol, exo-brevicomin, and frontalin, are thought to arise via...

Spatiotemporal integration of molecular and anatomical data in virtual reality using semantic mapping
Download2009
Janzen, R.P., Dong, X., Gordon, P.M., Soh, J., Wishart, D.S., Sabhaney, A., Turinsky, A.L., Sensen, C.W., Chang, J., Hau, D., Xia, J., Trinh, Q.M.
We have developed a computational framework for spatiotemporal integration of molecular and anatomical datasets in a virtual reality environment. Using two case studies involving gene expression data and pharmacokinetic data, respectively, we demonstrate how existing knowledge bases for molecular...

Alternative Requirements for Vestigial, Scalloped, and Dmef2 during Muscle Differentiation in Drosophila melanogaster
Download2009
Bell, J. B., Deng, H., Simmonds, A. J., Hughes, S. C.
Abstract: Vertebrate development requires the activity of the myocyte enhancer factor 2 (mef2) gene family for muscle cell specification and subsequent differentiation. Additionally, several muscle-specific functions of MEF2 family proteins require binding additional cofactors including members...

Effect of age of the intermediate host Tribolium confusum (Coleoptera) on infection by Hymenolepis diminuta (Cestoda).
Download2008
A cross-sectional study of 27 cohorts of Tribolium confusum aged 2–78 wk was done to examine effects of host age on exposure to eggs of Hymenolepis diminuta under standardized conditions. Pre-exposure, fasting, and postexposure mortality were low, sex ratio was equal, and fecundity of hosts was...
