Advances in Legume Systematics, part 10, Higher Level Systematics, pp. 5–35. Royal Botanic Gardens, Kew. RECONSTRUCTING THE PHYLOGENY OF LEGUMES (LEGUMINOSAE): AN EARLY 21ST CENTURY PERSPECTIVE MARTIN F. WOJCIECHOWSKI Department of Plant Biology, Arizona State University, Tempe, Arizona 85287 USA Abstract Elucidating the phylogenetic relationships of the legumes is essential for understanding the evolutionary history of events that underlie the origin and diversification of this family of ecologically and economically important flowering plants. In the ten years since the Third International Legume Conference (1992), the study of legume phylogeny using molecular data has advanced from a few tentative inferences based on relatively few, small datasets into an era of large, increasingly multiple gene analyses that provide greater resolution and confidence, as well as a few surprises. Reconstructing the phylogeny of the Leguminosae and its close relatives will further advance our knowledge of legume biology and facilitate comparative studies of plant structure and development, plant-animal interactions, plant-microbial symbiosis, and genome structure and dynamics. Phylogenetic relationships of Leguminosae — what has been accomplished since ILC-3? The Leguminosae (Fabaceae), with approximately 720 genera and more than 18,000 species worldwide (Lewis et al., in press) is the third largest family of flowering plants (Mabberley, 1997). Although greater in terms of the diversity of forms and number of habitats in which they reside, the family is second only perhaps to Poaceae (the grasses) in its agricultural and economic importance, and includes species used for foods, oils, fibre, fuel, timber, medicinals, numerous chemicals, cultivated horticultural varieties, and soil enrichment.

  • Potent Poisonous Compounds from Elaeodendron Croceum
    384 SAAB Annual Meeting Abstracts Potent poisonous compounds from Elaeodendron croceum A new chlorophenol, 1-hydroxy-5-chlorophenylhepta-1,3,5-triyne (triyne), was isolated as the major phenolic compound from a Helichrysum aureonitens cell T. Yelani, A.A. Hussein, J.J.M. Meyer suspension culture. The methyl ether form of triyne has been previously isolated Department of Plant Science, University of Pretoria, Pretoria 0002, South Africa from H. coriaceum. The flavonoids, galangin and kaempferol, which are present in leaves of H. aureonitens was not detectable in the cell suspension extract. The results of GC/MS analyses on the leaves of H. aureonitens showed that the species Several authors have reported that most parts of Elaeodendron croceum are contain 4' hydroxylated and non-hydroxylated flavonoids as well as their poisonous. “Witchdoctors” apparently previously used the species to cause death respective precursors, pinobanksin and naringenin. This finding has not been and the bark has been reported to be fatal to humans, presumably due to the reported before and our investigation on the biosyntheses of these flavonoids presence of alkaloids. The plant has also been suspected as the cause of human resulted in the detection of a new variation on the C4H gene that is playing a key death in at least two court cases. A phytochemical investigation of the poisonous role in an alternative biosynthetic route for 4′ hydroxylated flavonoids. leaves of E. croceum guided by cytotoxicity against Vero cells, led to the isolation of five compounds; 20-hydroxy-20-epi-tingenone (1), tingenone doi:10.1016/j.sajb.2008.01.132 (2), tingenine B (3), 11α-hydroxy-β-amyrin (4), and naringenin (5).
