Stomata, valves on the plant epidermis, are critical for plant growth and survival, and the presence of stomata impacts the global water and carbon cycle. Although transcription factors and cell-cell signaling components regulating stomatal development have been identified, it remains unclear as to how their regulatory interactions are translated into(More)
Analysis of plasma proteins avidly bound to T. pallidum surfaces revealed the ability of T. pallidum to acquire numerous host macromolecules. No acquisition was evident by the avirulent spirochete, T. phagedenis biotype Reiter. Western blotting technology using hyperimmune antifibronectin serum as a probe revealed the ability of virulent treponemes to(More)
Lactoferrin acquisition and iron uptake by pathogenic Trichomonas vaginalis was examined. Saturation binding kinetics were obtained for trichomonads using increasing amounts of radioiodinated lactoferrin, while no significant binding by transferrin under similar conditions was achieved. Only unlabeled lactoferrin successfully and stoichiometrically competed(More)
Human plasma low density lipoprotein uptake by the urogenital pathogen, Trichomonas vaginalis, was examined. Rapid binding and internalization of 125I-labeled low density lipoproteins by live T. vaginalis was observed at 37 degrees C. Data showing parasite degradation of the internalized apoproteins and lipid accumulation following low density lipoprotein(More)
The acquisition of lactoferrin and transferrin by live Treponema pallidum organisms was examined. Saturation binding kinetics were obtained for virulent treponemes with increasing amounts of radioiodinated lactoferrin but not with transferrin. Furthermore, lactoferrin bound up to 100 times more effectively than transferrin. Only unlabelled lactoferrin(More)
The flowering plant family Elatinaceae is a widespread aquatic lineage inhabiting temperate and tropical latitudes, including ∼35(-50) species. Its phylogeny remains largely unknown, compromising our understanding of its systematics. Moreover, this group is particularly in need of attention because the biogeography of most aquatic plant clades has yet to be(More)
A phage directing the synthesis of an abundant 45-kD Treponema pallidum surface protein was isolated from an EMBL-4 bacteriophage lambda library of T. pallidum DNA. The recombinant phage was identified using an mAb that was directed toward an immunodominant, outer envelope T. pallidum protein designated P6. The recombinant P6 protein possessed the same mol(More)
