  2. 1. Systematics of Echiochilon and Ogastemma (Boraginaceae), and the Phylogeny of Boraginoideae

    Author : Elisabeth Långström; Per Ola Karis; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organismic biology; Antiphytum; Echiochilon; Ogastemma; Boraginaceae; Echiochileae trib. nov.; phylogeny; ITS; floral morphology; atpB; tribes; biogeography; Africa; America; Organismbiologi; Organism biology; Organismbiologi; Systematisk botanik; Systematic Botany;

    Abstract : Echiochilon, Ogastemma and Sericostoma are revised resulting in the recognition of 15 species of Echiochilon and one Ogastemma species. Several species are placed in synonymy and three new species are described, E. baricum, E. callianthum and E. READ MORE

  4. 2. Phylogenetic Studies in the Euasterids II : with Particular Reference to Asterales and Escalloniaceae

    Author : Johannes Lundberg; Olof Ryding; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organismic biology; Organismbiologi; Organism biology; Organismbiologi; systematisk botanik; Systematic Botany;

    Abstract : The present study is concerned with the evolutionary relationships among the Euasterids II, a group of angiosperms that includes the orders Apiales, Aquifoliales, Asterales, and Dipsacales together with several small, poorly known families yet unplaced as to order.Parsimony analysis of nucleotide sequence data from the chloroplast genes atpB, ndhF and rbcL together with morphological data are used to construct a phylogeny of the order Asterals, which in the present sense includes 11 families and more than 26 000 species.

  5. 3. Mistletoes and Thionins : as Selection Models in Natural Products Drug Discovery

    Author : Sonny Larsson; Anders Backlund; Lars Bohlin; Peter J. Houghton; Uppsala universitet; []
    Keywords : Pharmacognosy; drug discovery; mistletoe; phylogeny; cytotoxic peptides; Santalales; Farmakognosi;

    Abstract : The process of drug discovery from natural products starts with the selection of study object. In this project recent knowledge and methods are incorporated to investigate the process of such selection for pharmacognostic investigations. READ MORE

  6. 4. Tracing History : Phylogenetic, Taxonomic, and Biogeographic Research in the Colchicum Family

    Author : Annika Vinnersten; Kåre Bremer; Bertil Nordenstam; Jerrold I Davis; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; biogeography; Colchicaceae; colchicine; dating; phylogeny; taxonomy; Biologi; Biology; Biologi;

    Abstract : This thesis concerns the history and the intrafamilial delimitations of the plant family Colchicaceae. A phylogeny of 73 taxa representing all genera of Colchicaceae, except the monotypic Kuntheria, is presented. READ MORE

  7. 5. Evolutionary Studies in Asterids Emphasising Euasterids II

    Author : Jesper Kårehed; Mats H. G. Gustafsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organismic biology; Apiales; Aquifoliales; Asterales; asterids; Bayesian inference; Cardiopteridaceae; DNA sequence data; Icacinaceae; morphology; parsimony; Pennantiaceae; phylogeny; Stemonuraceae; Organismbiologi; Organism biology; Organismbiologi; systematisk botanik; Systematic Botany;

    Abstract : This thesis deals with evolutionary relationships within the asterids, a group of plants comprising about one-third of all flowering plants.Two new families are recognised: Pennantiaceae and Stemonuraceae. The woody Pennantia from New Zealand and Australia is the sole genus of Pennantiaceae. READ MORE
