Lepage, B., Stockey, R., Currah, R.
Fossil ectomycorrhizae were found recently among permineralized plant remains in the middle Eocene Princeton chert of British Columbia. The ectomycorrhizae are associated with roots of Pinus and have a Hartig net that extends to the endodermis, a pseudoparenchymatous mantle, and contiguous...

Vegetative and fertile frond segments of Botrychium have been recovered from Paleocene deposits of central Alberta, Canada. Specimens are preserved as coalified compressions that yield information about frond structure, sporangia, and spore ultrastructure. These fossils, described as Botrychium...

Cohen, M. B., Andow, D. A., Romena, A. M., Gould, F., Bentur, J. S.
Abstract: Using the F-2 screen methodology, we estimated the frequency of alleles conferring resistance to the CrylAb toxin of Bacillus thuringiensis Berliner in a Philippine population of the stem borer Scirpophaga incertulas (Walker). Evaluation of >450 isofemale lines for survival of F-2...

Freshwater Sponges Have Functional, Sealing Epithelia with High Transepithelial Resistance and Negative Transepithelial Potential
Download2010
Leys, S.P., Goss, G.G., Adams, E.D.M.
Epithelial tissue — the sealed and polarized layer of cells that regulates transport of ions and solutes between the environment and the internal milieu — is a defining characteristic of the Eumetazoa. Sponges, the most ancient metazoan phylum [1], [2], are generally believed to lack true...

Understanding the joint impact of vaccination and non-pharmaceutical interventions on COVID-19 development is important for making public health decisions that control the pandemic. Recently, we created a method in forecasting the daily number of confirmed cases of infectious diseases by...

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...

Functional interaction between phosducin-like protein 2 and cytosolic chaperonin is essential for cytoskeletal protein function and cell cycle progression
Download2007
Pozniakovsky, A., Hyman, A.A., Stirling, P.C., Takhar, K.S., Srayko, M., Lerou, M.R.
The Chaperonin Containing Tcp1 (CCT) maintains cellular protein folding homeostasis in the eukaryotic cytosol by assisting the biogenesis of many proteins, including actins, tubulins, and regulators of the cell cycle. Here, we demonstrate that the essential and conserved eukaryotic phosducin-like...

Boutin, S., Zuleta, G., Krebs, C. J., O'Donoghue, M., Hofer, E. J., Murray, D. L.
Coyotes and lynx are the two most important mammalian predators of snowshoe hares throughout much of the boreal forest. Populations of hares cycle in abundance, with peaks in density occurring every 8-11 yr, and experimental results suggest that predation is a necessary factor causing these...

Sherman, E.L., Go, N.E., Nargang, F.E.
The TOM (translocase of the outer mitochondrial membrane) complex of the outer mitochondrial membrane is required for the import of proteins into the organelle. The core TOM complex contains five proteins, including three small components Tom7, Tom6, and Tom5. We have created single and double...
