    Relationships among Old and New World Alliums according to ITS DNA sequence analysis (1999)
    Springer
    Theoretical and applied genetics 98 (1999), S. 422-433

    ISSN: 1432-2242
    Keywords: Key words Allium ; Nectaroscordum ; Caloscordum ; Subgenus Amerallium ; Phylogeny ; ITS sequence analysis

    Topics: Biology
    Notes: Abstract  Phylogenetic analysis of ITS DNA sequences of various Old and New World Alliums suggests the reinclusion of Nectaroscordum and affirms the reestablishment of Caloscordum as subgenera of genus Allium. The results sanction the elimination of the Old World Allium species from subg. Amerallium Traub and endorse Wendelbo’s definition of subg. Molium (excluding sect. Porphyrason).

    Phylogeny of Allium L. subg. Melanocrommyum (Webb et Berth.) Rouy based on DNA sequence analysis of the internal transcribed spacer region of nrDNA (1998)

    Notes: Abstract  Sequence analysis of the ITS region of nuclear ribosomal DNA from subgeneric representatives of Allium L. produced phylogenetic trees which concurred with previous conclusions based on classical taxonomy. Phylogenetic analysis revealed a closer relationship between Nectaroscordum siculum and Allium cernuum (representing Amerallium) than between A. cernuum and the rest of the Allium species employed in this study. The phylogeny of subg. Melanocrommyum based on ITS sequences largely agreed with inferences made by previous researchers based on morphology or a restriction analysis of chloroplast DNA. However, the phylogenetic positions of Allium protensum and Allium macleanii based on ITS sequences did not correspond to their morphological similarity with Allium schubertii and Allium giganteum, respectively.

    ITS DNA sequence relationships between Lilium concolor Salisb., L. dauricum Ker-Gawl. and their putative hybrid, L. maculatum Thunb. (1999)
    Springer
    Theoretical and applied genetics 98 (1999), S. 213-218

    ISSN: 1432-2242
    Keywords: Key words ITS sequence analysis ; Cycle sequencing ; Lilium ; Hybrid verification

    Notes: Abstract  Cycle sequencing of the ITS region of nuclear ribosomal DNA of L. concolor, L. dauricum and L. maculatum generated surprisingly homogenous sequences from these three species. Analysis of the few (13 out of 639) polymorphic nucleotide sites in the ITS region produced results that do not support the belief that L. maculatum is a hybrid of the two other species. Neighbor-Joining analysis of the genetic distances calculated using the Kimura 2-parameter model of base substitution confirmed the close relationship between L. dauricum and L. maculatum. The phylogenetic tree, in conjunction with the distribution pattern and morphological similarities of the two species, suggest that L. maculatum is derived from the more widely distributed L. dauricum. The results also revealed that there is sufficient molecular divergence between L. maculatum and L. dauricum to support their status as separate species.
