To identify the means by which phytohemagglutinin (PHA) exerts its toxicity on the potato leafhopper, four different methods (thick and semi-thin sectioning combined with immunofluorescent staining, in vitro receptor autoradiography, and immunoelectron microscopy) were used to elucidate the PHA
The bean lectin phytohemagglutinin (PHA) was expressed in transgenic suspension-cultured BY-2 tobacco cells simultaneously with another recombinant vacuolar protein, the sweet potato sporamin. In contrast to previous observations in different transgenic plant systems when expressed in BY-2 tobacco
A factor which agglutinates the germinated spores of Ceratocystis fimbriata was isolated from the sweet potato root. The factor is a glycoprotein with a molecular weight of 1.6 x 10(6) daltons and required divalent cations such as Ca(2+), Mn(2+), Ni(2+), and Mg(2+) for activity. The activity of the
Naturally induced secretions from infective juveniles of the potato cyst nematode Globodera rostochiensis co-stimulate the proliferation of tobacco leaf protoplasts in the presence of the synthetic phytohormones alpha-naphthaleneacetic acid (NAA) and 6-benzylaminopurine (BAP). With the use of a
A total of 280 weaned pigs (Landrace x Yorkshire x Duroc) were used in a 28-d growth study to investigate the effect of feeding different levels of potato proteins on growth performance, nutrient digestibility, immune response, small intestinal morphology, and bacterial populations in feces and
We have previously reported the purification of a 37 kDa platelet agglutinating protein (PAP p37) from the plasma of a patient with thrombotic thrombocytopenic purpura (TTP) that was shown to be present in a subset of TTP patients. To gain further insight into the interaction between PAP p37 and
The plant-beneficial bacterium Azospirillum brasilense can swim in liquids and swarm or migrate with the formation of microcolonies in soft media. To get closer to understanding the influence of natural environments on A. brasilense motility, we studied the individual and social movement of the
