Molecular Phylogenetic Analysis of Novel Spiroplasma Isolates
… of the closely related spiroplasma isolates. Phylogenetic analyses and non-genetic character mapping indicated that all study isolates belonged to the Apis clade; arginine hydrolysis was a strong indicator of evolutionary relatedness; surface serology and phylogenetic placement were congruent; …

Phylogenetic Analysis of the Genus Pistacia (Anacardiaceae)
… vera L., and P. weinmannifolia Poiss. ex Franch. Phylogenetic analysis based on morphological data strongly supported the monophyly of Pistacia. The genus divided into two monophyletic groups. One group (Section Pistacia) contains P. atlantica, P. chinensis, P. eurycarpa, P. falcata, P. …

A phylogenetic analysis of the Accipitridae (class Aves).
… species groups (i.e., morphological types) an analysis of DNA sequence data from the mitochondrial encoded cytochrome-b gene was undertaken. Parsimony, distance and maximum likelihood methods were used to explore the phylogenetic relationships among the Accipitridae. Major findings of the …

Genetic characterisation and phylogenetic analysis of bovine astroviruses and kobuviruses
… in diarrhoeic and healthy calves by capsid gene analysis. As the AstV capsid protein is the major target of host antibody production, a serological test for AstV infection could then be developed. Following amplification of AstV capsid genes by PCR, phylogenetic analysis identified 4 lineages …

Molecular and phylogenetic analysis of a Bacillus thuringiensis genetic locus
… N-terminal amino acid, immunological and PCR analysis indicated that both strains contain a novel set of $\delta$-endotoxins. N-terminal amino acid sequence analysis indicated that the larger proteins from each strain (90 and 72-kDa of 84-I and 70 and 65-kDa of 17A) were related to the Cry …

Insight Into Human Brain Evolution Through Phylogenetic Analysis And Comparative Genomics
… of encephalization across mammals through a phylogenetic analysis in order to infer at which point significant changes in brain size occurred. We demonstrate that variation in brain size began in anthropoid primates. Furthermore, we show multiple lineages have evidence of brain expansion, …

A comparative and phylogenetic analysis of the genome of Pseudomonas aeruginosa
… analyses including a LC-MS metabolomics analysis of the CF isolates grown in artificial sputum media to mimic chronic lung infection. Further to this, in an attempt at mapping the core genome of P. aeruginosa and providing the community with a greater understanding of the genomic basis of …

Phylogenetic Analysis of Certain Lower Brachycerous Diptera in the Nearctic Region
… with one produced by a rooted Wagner cladistic analysis and by three phenetic analyses: the Pearson product-moment correlation coefficient, the average taxonomic distance, and the mean character distance. Six out-group genera are included for purposes of comparison.

Phylogenetic Analysis of Iliamna (Malvaceae) Using the Internal Transcribed Spacer Region
… and evolutionary history. Cladistic analysis was performed and the resulting phylogeny is presented. The ITS data provide new insights in the origination of the genus and its distribution. In Iliamna, the ITS region is 677 base pairs long with 120 sites providing information in the …

Phylogenetic Analysis of the Cetonini of the New World (Coleoptera: Scarabaeidae: Cetoninae)
… tribes of Cetoniinae, were included in a phylogenetic analysis and studied under the parsimony criterion. The Cetoniini, a tribe including species from all continents, is monophyletic and appears supported by two homoplastic characters: the elytra-thorax articulation in a glove-like shape …

Phylogenetic Analysis and Characterization of Plant, Environmental, and Clinical Strains of Pantoea
… their specific host ranges. Multilocus sequence analysis (MLSA) on six housekeeping genes of Pantoea revealed that some species are mixed, and contain plant, clinical, and environmental strains, while other species groups are composed of only plant or only clinical strains. Comparative growth …

Molecular Phylogenetic Analysis of Argynnis Fabricius (1807) including North American Speyeria Scudder (1872)
… Simonsen et al. 2006). Thus, no comprehensive phylogenetic analysis exists for all members that answers the question of monophyly of Speyeria , or other subgeneric taxa,and their relationship to Argynnis species. A phylogenetic analysis was completed of all North American Speyeria species and …

A Molecular and Phylogenetic Analysis of Cryobiosis in Nematodes of the Genus Panagrolaimus
… of the main aims of this project was to employ phylogenetic, proteomic, and transcriptomic approaches to gain insights into the adaptations that aid the survival of the free- living cryotolerant nematode Panagrolaimus superbus. Panagrolaimus sp. from temperate, subpolar, polar and continental …

Comparative and phylogenetic analysis of the early embryonic development in the phylum Nematoda
… In a first part of this thesis a comparative analysis of the early embryonic development was done on 21 nematode species belonging to clade 6 and clades 9-12 (phylogeny of Holterman et al., 2006). Our study revealed prominent differences between nematodes. Variations include differences in …

Phylogenetic Analysis of the Australian Genus <em>Pseudophryne</em> (Myobatrachidae) using Morphological Characters.
<p>The phylogenetic relationships of <em>Pseudophryne</em> and the closely related monotypic <em>Metacrinia</em> are resolved with the use of morphological characters and comparison with representatives species of <em>Crinia</em>, <em>Uperoleia</em>, and <em>Taudactylus</em> as defined out-groups. …

Mentha (Lamiaceae) Phylogenetic Analysis Using Chloroplast TRNL-TRNF and Nuclear Ribosomal DNA ITS Sequences
… of its traditionally recognized sections, assess phylogenetic relationships of the Mentha species, test hypotheses of hybridization for the putative stabilized allopolyploids (M spicata and M. canadensis), and determine the ancestral base chromosome number using DNA sequence data from the …

A Phylogenetic Analysis of Species Relationships in Hemlocks, the Genus <em>Tsuga</em> (Pinaceae).
… Europe and Japan. This study presents the first phylogenetic analysis based on structural, biochemical, and molecular sequence data. Characters obtained from published and unpublished literature were combined with new morphological characters from seeds, seedlings, and leaf cuticle material. …

Phylogenetic Analysis of the Mycobacteria and Diagnosis of Paratuberculosis by 16SrRNA Amplification and Probing
… thermotolerance, and virulence were shown to be phylogenetically restricted traits. The slow-growers formed a coherent line of descent, distinct from the rapid-growing mycobacteria. The analysis supported the species distinction for M. avium and M. intracellulare, the identification of M. …
