  2. 1. Deciphering sequence data : A multivariate approach

    Author : Maria Sandberg Hiltunen; Michael Sjöström; Svante Wold; Lars Ståhle; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Principal properties; amino acids; nucleotides; tRNA; DNA; multivariate data analysis; sequence analysis; QSAR; quantitative sequence activity relationships;

    Abstract : In this thesis, attention has been focused on the quantitative description of nucleic acids, proteins and peptides. The strategy was to use multivariate chemometrical methods for improving the understanding of the complex structural codes of these kinds of biological molecules. READ MORE

  4. 2. Reticulate Evolution in Diphasiastrum (Lycopodiaceae)

    Author : Sunniva Margrethe Due Aagaard; Niklas Wikström; Tom A. Ranker; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; admixture analysis; Bayesian clustering; Diphasiastrum; Feulgen DNA image densitometry; homoploid hybridization; Lycopodiaceae; phylogenetic analysis; polyploidy; reticulate evolution; Systematics and phylogenetics; Systematik och fylogeni; systematisk botanik; Systematic Botany;

    Abstract : In this thesis relationships and the occurrence of reticulate evolutionary events in the club moss genus Diphasiastrum are investigated. Diphasiastrum is initially established as a monophyletic group within Lycopodiaceae using non recombinant chloroplast sequence data. READ MORE

  5. 3. Computational Prediction Models for Proteolytic Cleavage and Epitope Identification

    Author : Liwen You; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; medical informatics; biomathematics biometrics; Bioinformatics; SVM; sequence analysis; rule extraction; protease-peptide interaction; OSRE; MHC; immunology; HIV; hierarchical method; HCV; Gaussian process; false positive; epitope; cleavage specificity; cleavage prediction; binding affinity; caspase; Bioinformatik; medicinsk informatik; biomatematik; Computer science; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll; Binding affinity; Bioinformatics;

    Abstract : The biological functions of proteins depend on their physical interactions with other molecules, such as proteins and peptides. Therefore, modeling the protein-ligand interactions is important for understanding protein functions in different biological processes. READ MORE

  6. 4. Diversity Underfoot : Systematics and Biogeography of the Dictyostelid Social Amoebae

    Author : Allison L Perrigo; Sandra Baldauf; Maria Romeralo; David Bass; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Amoeba; biogeography; cryptic species; dictyostelid; latitudinal gradient; multicellularity; protist; social amoeba; phylogenetics; systematics; new species; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Abstract : Dictyostelids (Amoebozoa) are a group of social amoebae consisting of approximately 150 species, which are found in terrestrial habitats worldwide. They are divided into eight major clades based on molecular phylogeny, and within these clades are many species complexes. READ MORE

  7. 5. Spikemoss patterns : Systematics and historical biogeography of Selaginellaceae

    Author : Stina Weststrand; Petra Korall; Michael J. Donoghue; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; classification; historical biogeography; lycophytes; nomenclature; phylogeny; Selaginella; Selaginellaceae; systematics; fylogeni; historisk biogeografi; klassifikation; lummerväxter; nomenklatur; Selaginella; Selaginellaceae; systematik; Biologi med inriktning mot systematik; Biology with specialization in Systematics;

    Abstract : Selaginellaceae, spikemosses, is a heterosporous plant family belonging to the lycophytes. With an estimated age of some 350 million years, the family is historically important as one of the oldest known groups of vascular plants. Selaginellaceae is herbaceous with a worldwide distribution. However, the majority of the ca. READ MORE
