  2. 1. Evolution and biodiversity of the Ixoroideae (Rubiaceae)

    Author : Kent Kainulainen; Birgitta Bremer; Sylvain Razafimandimbison; Torsten Eriksson; Sandra Knapp; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alberteae; character evolution; classification; Condamineeae; fruit evolution; Ixoroideae; phylogenetics; pollen presentation; Rubiaceae; systematics; taxonomy; Systematics and phylogenetics; Systematik och fylogeni; växtsystematik; Plant Systematics;

    Abstract : The phylogenetic relationships within subfamily Ixoroideae of the coffee family are investigated by phylogenetic reconstruction of molecular data, including regions of the chloroplast DNA (matK, ndhF, rbcL, rps16, trnH-psbA, trnS-G, and trnT-F), and the nuclear ribosomal DNA (ITS). The evolution of morphological characters within the group are inferred, with focus on characters used in classification. READ MORE

  4. 2. Phylogeny and topological incongruence in the Rubioideae (Rubiaceae)

    Author : Olle Thureborn; Catarina Rydin; Sylvain G. Razafimandimbison; Niklas Wikström; Michael D. Pirie; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Anthospermeae; cytonuclear discordance; gene trees; incomplete lineage sorting; incongruence; mitochondrial genome; nuclear genome; phylogenomics; phylogeny; plastid genome; Rubiaceae; Rubioideae; species trees; Plant Systematics; växtsystematik;

    Abstract : The work with this thesis has focused on evolutionary relationships in the Rubioideae, the most species-rich subfamily of the large and diverse coffee family (Rubiaceae). Despite considerable efforts during the last decades, uncertainty regarding several relationships in this group has remained, either as a result of unconvincing statistic support, incongruent results, or insufficient taxon sampling.

  6. 4. Phylogenetic Studies in the Gentianales – Approaches at Different Taxonomic Levels

    Author : Maria Backlund; Mats Thulin; Birgitta Bremer; Kåre Bremer; Mikael Hedrén; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Gentianales; phylogeny; classification; rbcL; trnT-F; rps16; ndhF ndh; Paederieae; Putorieae; Rubiaceae; Loganiaceae; Buddlejaceae; Gelsemiaceae; Apocynaceae; Gentianaceae; Biologi; Biology; Biologi;

    Abstract : This thesis deals with phylogenetic relationships at different taxonomic levels. All the plants studied are or have been included in the order Gentianales, which comprises about 17 200 species. READ MORE

  7. 5. Taxonomy and phylogeny of Randia (Rubiaceae, Gardenieae)

    Author : Claes G. R. Gustafsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; botany; taxonomy; phylogeny;

    Abstract : The Neotropical genera Rosenbergiodendron and Randia have been studied. Rosenbergiodendron is revised and presented in a separate paper. The other three papers concern Randia, which is partly revised and phylogenetically analysed. Rosenbergiodendron is morphologically distinct and cannot be synonymised under Randia. READ MORE
