  • Punctuated genome size evolution in Liliaceae.
    Journal of evolutionary biology, 2007
    Co-Authors: Ilia J. Leitch, Jeremy M. Beaulieu, K. Cheung, Lynda Hanson, Martin A. Lysak, Michael F. Fay
    Abstract:

    Most angiosperms possess small genomes (mode 1C = 0.6 pg, median 1C = 2.9 pg). Those with truly enormous genomes (i.e. ≥ 35 pg) are phylogenetically restricted to a few families and include Liliaceae – with species possessing some of the largest genomes so far reported for any plant as well as including species with much smaller genomes. To gain insights into when and where genome size expansion took place during the evolution of Liliaceae and the mode and tempo of this change, data for 78 species were superimposed onto a phylogenetic tree and analysed. Results suggest that genome size in Liliaceae followed a punctuated rather than gradual mode of evolution and that most of the diversification evolved recently rather than early in the evolution of the family. We consider that the large genome sizes of Liliaceae may have emerged passively rather than being driven primarily by selection.

  • 597. TULIPA SPRENGERI
    Curtis's Botanical Magazine, 2007
    Co-Authors: Richard Wilford, Michael F. Fay
    Abstract:

    Summary The distinctive Tulipa sprengeri Baker (Liliaceae) is illustrated and described. Its history, classification and cultivation requirements are discussed, including the results of recent research at Kew that establishes its position within the genus.

  • Molecular phylogenetic evidence for the monophyly of Fritillaria and Lilium (Liliaceae; Liliales) and the infrageneric classification of Fritillaria.
    Molecular phylogenetics and evolution, 2005
    Co-Authors: Nina Rønsted, Michael F. Fay, Steve Law, Hannah Thornton, Mark W. Chase
    Abstract:

    We present phylogenetic analyses of 37 taxa of Fritillaria (Liliaceae), 15 species of Lilium, and several outgroup taxa from Liliaceae s.s. to investigate the generic delimitation of Fritillaria in relation to Lilium as well as infrageneric relationships within Fritillaria. We used DNA sequences from the maturase-coding plastid matK gene and the trnK intron, the intron of the ribosomal protein-coding rpl16 plastid gene, and the nuclear ribosomal internal transcribed spacers (ITS). Phylogenetic analysis using maximum parsimony defined Fritillaria and Lilium (the latter including Nomocharis) as sister taxa. Fritillaria sections Fritillaria and Liliorhiza are supported in part, and some of the most enigmatic species usually included in Fritillaria (sections Petilium and Theresia and the monotypic genus Korolkowia) are closely related. The results support the new classification of Fritillaria proposed by Rix. We postulate independent origins of the underground bulbils found in Fritillaria davidii and the remainder of subgenus Liliorhiza.
