“Placing amoeboid lineages on the eukaryotic tree of life is difficult due to the paucity of comparable morphological characters

and the limited molecular data available for many groups. This situation has led to the lumping of distantly related lineages into large inclusive groups, such as Sarcodina, that do not reflect evolutionary relationships. Previous analyses of molecular markers with limited taxon sampling reveal members of Sarcodina are scattered in five of the six proposed supergroups. We have used multigene analyses to place seven diverse amoeboid lineages-two Nolandella spp., Rhizamoeba sp., Pessonella sp., Arcella hemisphaerica, Arachnula sp. and Trichosphaerium sp-on the eukaryotic tree of life. Bayesian analysis of the concatenated data of the four see more genes sequenced (SSU-rDNA, actin, alpha-tubulin and beta-tubulin), including diverse representatives of eukaryotes, indicates that all seven taxa group within the ‘Amoebozoa’ supergroup. We further performed separate analyses of the well-sampled SSU-rDNA and actin genes using Bayesian and Maximum Likelihood analyses to assess the positions of our newly characterized taxa. In the case of SSU-rDNA, we performed extensive

analyses with removal of the fastest rates classes to evaluate the stability and resolution of various taxonomic hypotheses within ‘Amoebozoa’. Five of our seven amoeboid lineages fall within well-supported clades that are corroborated by morphology. In contrast, the positions of Arachnula sp. and Trichosphaerium sp. in the SSU-rDNA gene trees are unstable and vary by analyses. Placement JQ1 of these taxa will require additional data from slowly evolving genes combined with taxon-rich phylogenetic

analyses. Finally, the analyses without the fastest rate classes demonstrate that SSU-rDNA has a limited signal for deep relationships within the ‘Amoebozoa’. (C) 2007 Elsevier Inc. All rights reserved.”
“2-((4- Methoxyphenoxy) carbonyl) benzoic acid, 2-(1-methoxyvinyl) benzoic acid and their rare earth complexes LnL(2)(OH) 3H(2)O (Ln = La, Eu, Tb) were synthesized and characterized by means of elemental analysis. FTIR, (1)H NMR. UV and luminescence spectroscopy The FTIR and (1)H NMR results show that the carboxylic groups in the complexes coordinated to the rare earth ions in the form of one dentate, and the ester carboxylic groups have taken part in the coordination Among these complexes, Eu(III) complexes and Tb(III) complexes exhibit characteristic fluorescence with comparatively high brightness and good monochromaticity. which indicated that the ligands of HL(I) and HL(II) are good organic chromophore to absorb and transfer energy to metal ions (C) 2009 Elsevier B.V.
