Dwarf french beans, Phaseolus vulgaris L., were grown with or without inoculation with rhizobia (strain 3644), and with or without a combined nitrogen source (nitrate or ammonium ions). The distribution of radioactivity into products of dark (14)CO2 assimilation was studied in roots or nodules from
There are three mammalian Golgi alpha1,2-mannosidases, encoded by different genes, that form Man5GlcNAc2 from Man(8-9)GlcNAc2 for the biosynthesis of hybrid and complex N-glycans. Northern blot analysis and in situ hybridization indicate that the three paralogs display distinct developmental and
The effect of raw jackbean (Canavalia ensiformis) or limabean (Phaseolus lunatus) seeds at 0, 250 or 500 g/kg in broiler chick diets for 28 d on performance and cytopathological changes in internal organs was evaluated. Relative pancreas weight increased significantly (P < 0.05) and the lungs had
High concentrations of cephalothin or penicillin G inhibit a number of the functions of human or rabbit platelets in citrated platelet-rich plasma (PRP) and in suspensions of washed platelets. The reactions shown to be inhibited are: ADP-induced shape change and the primary and secondary phases of
Factor XI (FXI) deficiency is associated with an abnormal bleeding state. The extent of bleeding does not correlate well with the plasma concentration of FXI, and it has been suggested that also unknown factors interfere with the bleeding tendency. In a recent paper (Thromb. Res. 74, 477-485, 1994)
Two microcystins, MC-LR and [D-Leu1]MC-LR, present in La Plata Basin blooms, are differentiated by substitution of D-Alanine for D-Leucine at position 1. Our objective was to evaluate acute toxicity of [D-Leu1]MC-LR and MC-LR in mice (N:NIH Swiss) and beans (Phaseolus
