  1. 16. Evolutionary Studies in Asterids Emphasising Euasterids II

    Författare :Jesper Kårehed; Mats H. G. Gustafsson; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 17. Phylogenetic Studies in the Euasterids II : with Particular Reference to Asterales and Escalloniaceae

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

    Sammanfattning : 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.

  4. 18. Systematics of Echiochilon and Ogastemma (Boraginaceae), and the Phylogeny of Boraginoideae

    Författare :Elisabeth Långström; Per Ola Karis; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 19. Synthesis of jojoba-like wax esters in metabolically engineered strains of Saccharomyces cerevisiae

    Författare :Leonie Wenning; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Saccharomyces cerevisiae; very long-chain monounsaturated fatty alcohols; very long-chain monounsaturated fatty acids; jojoba-like wax esters;

    Sammanfattning : Yeast has a long-standing tradition in human history as a production organism of choice. Besides being used for the production of fermented products like bread or beer, it has also been extensively explored for the production of proteins and chemicals. LÄS MER

  7. 20. Rhodothermus marinus: a cell factory : Exploring products and cultivation technology

    Författare :Emanuel Ron; Bioteknik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Rhodothermus marinus; Extremophiles; Carotenoids; Exopolysaccharides;

    Sammanfattning : The unsustainable human impact on ecology and ensuing climate change necessitates the reduction of greenhouse gas emissions. The largest contributing industrial sector is the chemical industry, due to its petrochemical dependency. LÄS MER
