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...

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...

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...

Resistance of some cultivated Brassicaceae to infestations by Plutella xylostella (Lepidoptera: Plutellidae)
Download2007
Sarfraz, M., Dosdall, L. M., Keddie, B. A.
Abstract: Selecting insect-resistant plant varieties is a key component of integrated management programs of oligophagous pests such as diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), but rigorous research on important life history parameters of P. xylostella in relation to...

Tolerance to neonatal porcine islet xenografts induced by a combination of monoclonal antibodies
DownloadFall 2009
Islet transplantation is a more physiological way to treat type 1 diabetes. However, shortage of donor tissue and chronic administration of immune suppressive drugs has limited the widespread application of this therapy for all patients with type 1 diabetes, particularly children suffering from...

The main function of co-inhibitory molecules is to regulate T cell immune responses by providing negative signals to those cells. Homeostatic activation of T cells occurs in both natural and artificially induced states of lymphopenia. Although lymphopenia leads to homeostatic proliferation of T...

Establishing mixed hematopoietic chimerism is a promising approach to develop donor-specific tolerance to transplanted organs. Establishing tolerance may eliminate the need for long-term immunosuppressive therapy, prevent chronic rejection and in the case of Type 1 Diabetes (T1DM), reverse...

Role of adventitious roots in water relations of tamarack (Larix laricina) seedlings exposed to flooding
Download2012
Calvo-Polanco, M., Senorans, J., Zwiazek, J.J.
Background: Flooding reduces supply of oxygen to the roots affecting plant water uptake. Some flooding-tolerant tree species including tamarack (Larix laricina (Du Roi) K. Koch) produce adventitious roots in response to flooding. These roots were reported to have higher hydraulic conductivity...

Pfrengle, Fabian, Paulson, James C., Gale, Andrew J., Nycholat, Corwin M., von Drygalski, Annette, Rademacher, Christoph, Macauley, Matthew S.
Antibodies confer humoral immunity but can also be harmful when they target an autoantigen, alloantigen, allergen, or biotherapeutic. New strategies are needed for antigen-specific suppression of undesired antibody responses, particularly to T cell–dependent protein antigens, because they elicit...
