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...

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...

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,...

Background: The MS4A gene family in humans includes CD20 (MS4A1), FcRb (MS4A2), Htm4 (MS4A3), and at least 13 other syntenic genes encoding membrane proteins, most having characteristic tetraspanning topology. Expression of MS4A genes is variable in tissues throughout the body; however, several...

Purification and characterization of an anaerobically induced alanine aminotransferase from barley roots
Download1992
Alanine aminotransferase (AlaAT, EC 2.6.1.2) is an enzyme that is induced under anaerobic conditions in cereal roots. In barley (Hordeum vulgare L.) roots, there are a number of isoforms of AlaAT. We have identified the anaerobically induced isoform and have purified it to homogeneity. The...

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...

Chen, A., Grey, C.L., Wong, A.O.L., Somoza, G.M., López, G.C., Canosa, L.F., Zhao, E., Trudeau, V.L., Chang, J.P., Basak, A., Ko,W.
Pituitary adenylate cyclase-activating polypeptide (PACAP) is a member of the glucagon/secretin peptide family, and its molecular structure is highly conserved in vertebrates. In this study, the functional role of PACAP in regulating GH release in the goldfish was investigated. Using...
