The APETALA-2-Like Transcription Factor OsAP2-39 Controls Key Interactions between Abscisic Acid and Gibberellin in Rice
Download2010
Rothstein, Steven J., Bi, Yong-Mei, Zhu, Tong, El-kereamy, Ashraf, Beatty, Perrin H., Yaish, Mahmoud W., Good, Allen G.
The interaction between phytohormones is an important mechanism which controls growth and developmental processes in plants. Deciphering these interactions is a crucial step in helping to develop crops with enhanced yield and resistance to environmental stresses. Controlling the expression level...

Lepage, B. A., Currah, R. S., Stockey, R. A.
The middle Eocene Princeton chert locality in southern British Columbia, Canada, contains one of the best-preserved permineralized Tertiary floral assemblages known in North America. The quality of pres- ervation of the vascular plant and fungal remains is exquisite because anatomical and...

The potential of aspen clonal forestry in Alberta: breeding regions and estimates of genetic gain from selection
Download2012
Brouard, J.S., Hamann, A., Gylander, T., Thomas, B.R.
Background: Aspen naturally grows in large, single-species, even-aged stands that regenerate clonally after fire disturbance. This offers an opportunity for an intensive clonal forestry system that closely emulates the natural life history of the species. In this paper, we assess the potential of...

The root distribution, architecture, transpiration and root sapflow dynamics of mature trembling aspen (Populus tremuloides) growing along a hillslope
DownloadFall 2013
The objectives of this study were to explore comparative controls by atmospheric and belowground variables governing transpiration of trembling aspen (Populus tremuloides) growing along a water limited hillslope. Vertical and horizontal root distribution, intra- and inter-clonal root connections,...

Wasylishen, R. E., Bernard, G. M., Quideau, S. A., Norris, C. E., Landhausser, S. M.
Abstract: Enriching plant tissues with C-13 and N-15 isotopes has provided long-lasting, non-reactive tracers to quantify rates of terrestrial elemental fluxes (e.g., soil organic matter decomposition). However, the molecular location and level of isotope enrichment may differ among plant...

Use of Indices of Biological Integrity (IBIs) to assess wetland health in dry and wet conditions
DownloadSpring 2012
Indices of Biological Integrity (IBIs) estimate the biological condition of an ecosystem by measuring biological metrics that predict underlying environmental stress. I evaluated the use of IBIs developed from 5 biotic communities at 81 semi-permanent/permanent natural and constructed wetlands. ...

Vegetative Growth of Eorhiza arnoldii Robison and Person from the Middle Eocene Princeton Chert Locality of British Columbia.
Download1994
Anatomical studies of several thousand specimens of Eorhiza arnoldii Robison and Person rhizomes and their attached organs have added significantly to our knowledge of these Middle Eocene, semiaquatic dicotyledonous plants from the Princeton chert. Anatomical structure of Eorhiza was studied...
