Rivard, B., Vinebrooke, R.D., Michelutti, N., Wolfe, A.P.
A new application of reflectance spectroscopy enables inferences of lake sediment chlorophyll a concentrations and hence of historical trends in lacustrine primary production. In a survey of six arctic lakes on Baffin Island (Nunavut, Canada), pronounced increases of spectrally-inferred...

Reclamation for aspen revegetation in the Athabasca oil sands: Understanding soil water dynamics through unsaturated flow modelling
Download2012
Smerdon, B.D., Mendoza, C.A., Devito, K.J., Petrone, R.M., Carrera-Hernandez, J.J.
Reclamation of mined areas in the Athabasca oil sands region is required by law, with the ultimate goal of revegetating to species characteristic of predisturbance native plant communities. To develop adequate reclamation strategies, an analysis of soil water dynamics is of utmost importance, as...

Reconstituted TOM core complex and Tim9/Tim10 complex of mitochondria are sufficient for translocation of the ADP/ATP carrier across membranes
Download2004
Habib, S.J., Panneels, V., Vasiljev, A., Prokisch, H., Nussberger, S., Neupert, W., Sinning, I., Nargang, F.E., Ahting, U., Rapaport, D., Go, N.E., Kozany, C.
Precursor proteins of the solute carrier family and of channel forming Tim components are imported into mitochondria in two main steps. First, they are translocated through the TOM complex in the outer membrane, a process assisted by the Tim9/Tim10 complex. They are passed on to the TIM22...

Reconstructing Emporia Lockardii (Voltziales:Emporiaceae) and Initial Thoughts on Paleozoic Conifer Ecology
Download2009
Stockey, R.A., Rothwell, G.W., Hernandez-Castillo, G.R., Mapes, G.
A new plant concept for the extinct conifer species Emporia lockardii (Mapes&Rothwell) Mapes&Rothwell (Emporiaceae) is developed from fossils collected at the Late Pennsylvanian Hamilton Quarry, Kansas. Emporia lockardii has lateral plagiotropic branches with simple and forked leaves, simple...

Recovery from open channel block by acetylcholine during neuromuscular transmission in larval zebrafish
Download2000
Legendre, P., Ali, D.W., Drapeau, P.
At larval zebrafish neuromuscular junctions (NMJs), miniature end plate currents (mEPCs) recorded in vivo have an unusually fast time course. We used fast-flow application of acetylcholine (ACh) onto outside-out patches to mimic the effect of synaptic release onto small numbers of ACh receptor...

In photosynthetic organisms it is becoming increasingly evident that light-driven shifts in redox potential act as a sensor that initiates alterations in gene expression at both the level of transcription and translation. This report provides evidence that the expression of a cyanobacterial RNA...

Purpose: Although specific genes play a role in regional retinal disease, the correlation of regional gene expression in the disease-affected site has not been previously ascertained. Non-human primates are widely used in models of human retinal function and are theorized to have identical (to...

The plant vascular system transports water and nutrients, but also regulatory molecules that function in short- and long-distance mechanisms to pattern surrounding tissues. As such, the development of the vascular system is tied to the overall patterning and development of the plant body. The...

Regulation of cold shock-induced RNA helicase gene expression in the cyanobacterium Anabaena sptrain PCC 7120
Download2000
Owttrim, George W., Chamot, Danuta
Expression of the Anabaena sp. strain PCC 7120 RNA helicase gene crhC is induced by cold shock.crhC transcripts are not detectable at 30°C but accumulate at 20°C, and levels remain elevated for the duration of the cold stress. Light-derived metabolic capability, and not light per se, is required...

Coleman, John R. , Owttrim, George W.
The expression of the cyanobacterial recA gene, isolated from Anabaena variabilis, has been examined at the levels of transcript and protein abundance. Exposure of the cyanobacterium to a variety of DNA-damaging agents, including mitomycin C, methyl methanesulfonate, and UV irradiation, results...
