Differential exudation of polypeptides by roots of aluminum-resistant and aluminum-sensitive cultivars of Triticum aestivum L. in response to aluminum stress
Download1994
Basu, A., Taylor, G. J., Basu, U.
Cultivars of Triticum aestivum differing in resistance to Al were grown under aseptic conditions in the presence and absence of Al and polypeptides present in root exudates were collected, concentrated, and analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Upon exposure to...

Diurnal and annual exchanges of mass and energy between an aspen-hazelnut forest and the atmosphere: testing the mathematical model ecosys with data from the BOREAS experiment

Russell, C., den Hartog, G., Grant, R.F., Berry, J.A., Yang, P.C., Neumann, H.H., Blanken, P.D., Black, T.A., Gower, S.T.
There is much uncertainty about the net carbon (C) exchange of boreal forest ecosystems, although this exchange may be an important part of global C dynamics. To resolve this uncertainty, net C exchange has been measured at several sites in the boreal forest of Canada as part of the Boreal...

Bohnert, H. J., Deyholos, M., Brazille, S., Wang, H., Kawai, K., Borchert, C., Galbraith, D., Kawasaki, S.
Transcript regulation in response to high salinity was investigated for salt-tolerant rice (var Pokkali) with microarrays including 1728 cDNAs from libraries of salt-stressed roots. NaCl at 150 mM reduced photosynthesis to one tenth of the prestress value within minutes. Hybridizations of RNA to...

Induction of microsomal membrane proteins in roots of an aluminum-resistant cultivar of Triticum aestivum L. under conditions of aluminum stress
Download1994
Basu, U., Basu, A., Taylor, G. J.
Three-day-old seedlings of an Al-sensitive (Neepawa) and an Al-resistant (PT741) cultivar of Triticum aestivum were subjected to Al concentrations ranging from a to 100 mu M for 72 h. At 25 mu M Al, growth of roots was inhibited by 57% in the Al-sensitive cultivar, whereas root growth in the...

Abstract: During a survey of microfungi from rotting wood in northern Alberta forests, 49 species of ascomycetes, representing 24 genera, and 15 families in seven orders, were recovered. Twenty-eight species are new reports for Alberta, 15 of which are new for Canada, and seven are new for North...

Modulation of citrate metabolism alters aluminum tolerance in yeast and transgenic canola overexpressing a mitochondrial citrate synthase
Download2003
Basu, U., Anoop, V. M., Taylor, G. J., McAlister-Henn, L., McCammon, M. T.
Aluminum (Al) toxicity is a major constraint for crop production in acid soils, although crop cultivars vary in their tolerance to Al. We have investigated the potential role of citrate in mediating Al tolerance in Al-sensitive yeast (Saccharomyces cerevisiae; MMYO11) and canola (Brassica napus...

Pinus Pollen Cones from the Middle Eocene Princeton Chert (Allenby Formation) of British Columbia, Canada.
Download1995
Stockey, R.A., Osborn J.M., Phipps, C.J.
Anatomically preserved pollen cones are described from the Middle Eocene Princeton chert of British Columbia, Canada. Cones are ellipsoidal; range from 2.8 to 6.9 mm in length, 1.6 to 3.5 mm in diameter; and are often subtended by scale leaves. Cone axes contain longitudinally oriented, cortical...

Potential carbon losses from peat profiles: effects of temperature, drought cycles and fire
Download1992
Wein, R. W., Hogg, E. H., Lieffers, V. J.
Abstract: Global warming and the resultant increase in evapotranspiration might lead to lowered water tables in peatlands and an increase in fire frequency. The objective of this study was to investigate some of the potential effects of these changes on peat decomposition. Dry mass losses and...
