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...

Hannon, S., Stephenson, S., Proctor, H.
Altricial young face two significant energetic challenges in the nest: thermoregulation and stress caused by ectoparasites. Ectoparasites feed on blood of nestlings and serve as vectors for bacterial and viral infections. Many bird species line their nests with feathers, which insulate the nest...

Reid, T.A., Cahill, J.F., Navabi, A.
Competition with weeds decreases crop yields globally. Breeding for competitive ability against elevated weed pressure can be difficult because the selection for specific traits which contribute to competitive ability may result in yield losses. The widely studied International Triticeae Mapping...

Manipulation of host food availability and use of multiple exposures to assess the crowding effect on Hymenolepis diminuta in Tribolium confusum
Download2008
Walsh, J.G., Wong, Y.C., Shostak, A.W.
We studied the ‘crowding effect’ in Tribolium confusum infected with Hymenolepis diminuta. Manipulations included age and number of parasites, and diet, sex, age and number of exposures of hosts. Volume per parasite was unaffected until an intensity of at least 5–10 parasites per host, then...

Diet and Growth of Northern Pike in the Absence of Prey Fishes: Initial Consequences for Persisting in Disturbance-Prone Lakes.
Download2006
Venturelli, P. A., Tonn, W. M.
The northern pike Esox lucius is a renowned piscivore, but will prey opportunistically on invertebrates (e.g., in small lakes of boreal Alberta, where winterkill can unexpectedly reduce or eliminate prey fishes). We emulated such a disturbance by stocking a fishless lake with northern pike and...

Age determination of a long-lived coregonid from the Canadian North: comparison of otoliths, fin rays and scales in inconnu (Stenodus leucichthys)
Download2004
Gendron, M., Tonn, W.M., Howland, K.L., Tallman, R.F.
We examined otoliths, pelvic fin rays and scales of inconnu to determine precision of age estimates within and between readers, and to compare relative accuracy of estimates from different structures. Our main objective was to determine if readability and estimates from fin rays and scales,...

Optimizing exponential growth of Triticum aestivum by application of the relative addition rate (RAR) technique utilizing a computer-controlled nutrient delivery system
Download2004
Matumoto-Pintro, Paula T., Pintro, José C., Taylor, Gregory J.
We conducted experiments designed to assess whether plants can be grown under conditions of low ionic strength simulating natural soil conditions. Wheat (Triticum aestivum, cv. Atlas 66) plants were grown using ten different relative nutrient addition rates (RAR) of nutrients (0.00, 0.06, 0.09,...

Reid, R. J., Rengel, Z., McDonald-Stephens, J. L., Hunter, D. B., Elmore, D., Taylor, G. J., Bertsch, P. M.
Quantitative information on the uptake and distribution of Al at the cellular level is required to understand mechanisms of Al toxicity, but direct measurement of uptake across the plasma membrane has remained elusive. We measured rates of Al transport across membranes in single cells of Chara...

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...
