    Phylogeny of Allium L. subgenus Rhizirideum (G. Don ex Koch) Wendelbo according to dot blot hybridization with randomly amplified DNA probes (1997)

    Notes: Abstract  Among 341 randomly amplified DNA sequences generated from 11 Allium species, 55 were purified by gel excision and subsequent reamplification by PCR. These were then used as probes in dot blot analysis to evaluate the relationships between 44 Allium accessions classified under the subgenus Rhizirideum. The hybridization signals were standardized and converted to Euclidean taxonomic distances. Unweighted Pair Group Mean analysis of the distance data generated a phyllogram which basically conformed to the classification system proposed by the Gatersleben (Germany) group. However, there was insufficient evidence to suppport the proposal to join A. chinense G. Don with A. virgunculae F. Maek. et Kitam. into sect. Sacculiferum or the recent suggestion to re-establish sect. Phyllodolon.

    Serial MRI in early Creutzfeldt-Jacob disease with a point mutation of prion protein at codon 180 (1995)

    Notes: Abstract We report a 66-year-old woman with histologically diagnosed Creutzfeldt-Jacob disease (CJD), followed with MRI from an early clinical stage. MRI demonstrated expansion of the high cortical signal on T2-weighted images, which differs from previous MRI reports of CJD. This patient followed an atypical clinical course: 16 months had passed before she developed akinetic mutism, and periodic sharp waves had not been detected on EEG after 2 years in spite of her akinetic mutism. Brain biopsy showed primary spongiform changes in the grey matter, and a point mutation of the prion protein gene at codon 180 was discovered using polymerase chain reaction direct sequencing and Tth 111 I cutting. This is the first case with the point mutation of the codon 180 variant with an atypical clinical course and characteristic MRI findings.

    Relationships among Old and New World Alliums according to ITS DNA sequence analysis (1999)
    Springer

    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).

    Phylogenetic analysis of the internal transcribed spacer region of Japanese Lilium species (1999)

    Notes: Abstract  The DNA from 16 Lilium species and one variety endemic to or naturalized in Japan were obtained and their internal transcribed spacer regions of nuclear ribosomal DNA (nrDNA) were amplified by PCR and sequenced by cycle sequencing. Phylogenetic analysis of the ITS sequences supported the validity of Comber’s classification system. It has also provided molecular evidence for the transfer of Lilium dauricum to sect. Sinomartagon. The phylogenetic relationships revealed by ITS DNA analysis were supported by previously published crossability data. The molecular phylogeny of Japanese Lilium species was discussed with reference to the putative migration routes of these species.

    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.
