  1. 1. Phylogeny and classification of the tribe Vanguerieae (Rubiaceae)

    Författare :Henrik Lantz; Torsten Eriksson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Vanguerieae; Rubiacaeae; phylogeny; classification; morphology; ITS; trnT-F; rpl16; Biologi; Biology; Biologi; systematisk botanik; Systematic Botany;

    Sammanfattning : Vanguerieae is a tribe in the mainly tropical angiosperm family Rubiaceae. The tribe currently comprises around 600 species in 27 genera, with the major part of the species distributed in Africa south of the Sahara. The phylogeny of the tribe was investigated using both molecular and morphological data. LÄS MER

  3. 2. Phylogenies and Secondary Chemistry in Arnica (Asteraceae)

    Författare :Catarina Ekenäs; Katarina Andreasen; Anders Backlund; Lynn Bohs; Uppsala universitet; []
    Nyckelord :Biology; phylogeny; ITS; ETS; RPB2; sesquiterpene lactones; PCA; bioassay; NF-κB; neutrophil; chloroplast; Biologi; Arnica; Asteraceae;

    Sammanfattning : The genus Arnica (Asteraceae) was investigated for phylogenetic relationships and sesquiterpene lactone (STL) content with the aims to trace the evolutionary history of the genus and to investigate possible congruencies between DNA sequence data, secondary chemistry, and biological activity. Complex evolutionary patterns in Arnica are evident from phylogenetic analyses of chloroplast regions (the rpl16 and rps16 introns and the psbA–trnH, ycf4–cemA, and trnT–L spacers), nuclear ribosomal regions (the internal and external transcribed spacers) and the nuclear low-copy DNA region coding for the second largest subunit of RNA polymerase II (RPB2) between exons 17 and 23.

  4. 3. Comparative Seed Morphology and Phylogenetics : Case Studies in Basal Angiosperms (ANITA) and Asterids (Lysimachia, Ericales)

    Författare :Il-Chan Oh; Mats Thulin; Arne A. Anderberg; Bertil Ståhl; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; systematisk botanik; Systematic Botany;

    Sammanfattning : The first half of the thesis deals with the seed morphology of members of the ANITA grade at the base of the angiosperm phylogeny (Amborella, Nymphaeales, Illiciales, Trimeniaceae, and Austrobaileyaceae), especially Illiciaceae and Schisandraceae. Seed characters support a major division between the New World and Old World species of Illicium. LÄS MER
