Molecular Phylogenetics and Breeding System Evolution of the Turneraceae Molecular Phylogenetics and Breeding System Evolution of the Turneraceae Paul D.J. Chafe A THESIS SUBMITTED TO THE FACULTY OF GRADUATE STUDIES IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE GRADUATE PROGRAM IN BIOLOGY YORK UNIVERSITY TORONTO, ONTARIO NOVEMBER 2009 Abstract This study examined the phylogenetic relationships among the species of the heterostylous plant family the Turneraceae, with a focus on a single genus, Piriqueta. It includes the first phylogenetic analysis of species from Old World species in the Turneraceae. Using combined ITS and ndhF sequence data several phylogenies were constructed. The sequence data generated resolved the family quite well, and was successful even at the sub generic level. The family was found to be composed of three or four clades, depending on the sequence data included and the type of analysis performed. These clades are the genus Turnera, the genus Piriqueta, a clade of mainland African species, and a clade composed of disjunct island endemics and Erblichia odorata, a Central American species. The results of this study indicate that there have been numerous breakdowns of heterostyly in the Turneraceae. Finally, I discuss intercontinental disjunctions and identify species whose historical taxonomic treatment requires revision based on the phylogenies constructed. iv Acknowledgments I would like to take this opportunity to thank Dr. Joel Shore for allowing me the opportunity to further my education.

A cladistic analysis of the subfamily Euphorbioideae was undertaken to elucidate the origin of the cyathium- bearing Euphorbieae and to provide hypotheses about evolutionary relationships within the subfamily. Twenty-one species representing most of the genera within the study group and three outgroup taxa from the subfamilies Acalyphoideae and Crotonoideae were selected for parsimony analysis. An unweighted parsimony analysis of 24 morphological characters resulted in five equally parsimonious trees with consistency indices of 0.67 and tree lengths of 39 steps. The strict consensus tree supported monophyly of the cyathium-bearing Euphorbieae. The sister group relationships of cyathium bearing Euphorbieae with Maprounea (subtribe Hippomaninae) were supported weakly, and the origin of cyathium is possibly in Hippomaneae, or in the common ancestor of Euphorbieae and remaining taxa of Euphorbioideae plus Acalyphoideae. Within the tribe Euphorbieae, both subtribes Euphorbiinae and Neoguilauminiinae are monophyletic, but the African endemic subtribe Anthosteminae is unresolved. The resulting trees support the monophyly of the tribe Stomatocalyceae while the tribe Hippomaneae does not consistently form a clade. Keywords: Cyathium; Euphorbieae; Phylogeny.

  • Biochemical Assessment of the Effect of Aqueous Leaf Extract of Euphorbia Heterophylla Linn on Hepatocytes of Rats
    IOSR Journal Of Environmental Science, Toxicology And Food Technology (IOSR-JESTFT) e-ISSN: 2319-2402,p- ISSN: 2319-2399. Volume 3, Issue 5 (Mar. - Apr. 2013), PP 37-41 www.Iosrjournals.Org Biochemical Assessment of the Effect of Aqueous Leaf Extract Of Euphorbia Heterophylla Linn on Hepatocytes of Rats Apiamu Augustine1, Evuen Uduenevwo Francis 2, Ajaja Uche Ivy3 1, 2 & 3( Department of Biochemistry, College of Natural and Applied Sciences, Western Delta University, Nigeria) Abstract: In recent years, the search for biologically active compounds from Euphorbia heterophylla in the treatment of different diseases has always been of great interest to researchers. In this present study, we investigated the effect of the aqueous leaf extract of the plant on hepatocytes using animal models. A total of twenty (20) wistar albino rats (150-240g) were used for the study. The rats were randomly divided into four experimental groups (A, B, C & D) comprising five rats per group. The control group was administered deionised water while the treatment groups were orally administered doses of the aqueous leaf extract of the plant( 100mg/kg, 200mg/kg and 300mg/kg body weights) by means of a gavage for two weeks. Total protein, albumin, urea nitrogen, alanine aminotransferase(ALT), aspartate aminotransferase(AST) and alkaline phosphatase(ALP) were the biochemical parameters assessed in this study. The results showed no significant difference(p>0.05 in the levels of the aforementioned parameters. The aqueous leaf extract of the plant indicated the presence of carbohydrates, saponins, tannins, flavonoids, alkaloids, terpenoids and steroids, but anthracene derivatives were absent. The results obtained in this study, therefore, justify the traditional use of the plant for food and medicinal purposes respectively.

It is similar to and was initially identified as P. f l a m m e a from which it can be distinguished by the cuneate leaf blade bases (vs. rounded), slightly discoloured leaves (vs. strongly discoloured), inflorescences of fewer flowers (1–3 vs. 3–6), olive-green calyx when dry (vs. blackened), and yellow corolla (vs. orange red). Piriqueta crenata is only known from a single small savanna nested in the semiarid Chapada Diamantina region, close to areas under anthropogenic influence. Therefore, we evaluate the species as Critically Endangered. Key words: floristics, Neotropics, savanna, taxonomy.

Author for correspondence: Paul E. Berry, [email protected] Abstract Euphorbia subg. Chamaesyce contains around 600 species and includes the largest New World radiation within the Old World-centered genus Euphorbia. It is one of the few plant lineages to include members with C3, C4 and CAM photosyn- thesis, showing multiple adaptations to warm and dry habitats. The subgenus includes North American-centered groups that were previously treated at various taxonomic ranks under the names of “Agaloma ”, “Poinsettia ”, and “Chamaesyce ”. Here we provide a well-resolved phylogeny of Euphorbia subg. Chamaesyce using nuclear ribosomal ITS and chloroplast ndhF sequences, with substantially increased taxon sampling compared to previous studies. Based on the phylogeny, we discuss the Old World origin of the subgenus, the evolution of cyathial morphology and growth forms, and then provide a formal sectional classification, with descriptions and species lists for each section or subsection we recognize.

  • First Steps Towards a Floral Structural Characterization of the Major Rosid Subclades
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2006 First steps towards a floral structural characterization of the major rosid subclades Endress, P K ; Matthews, M L Abstract: A survey of our own comparative studies on several larger clades of rosids and over 1400 original publications on rosid flowers shows that floral structural features support to various degrees the supraordinal relationships in rosids proposed by molecular phylogenetic studies. However, as many apparent relationships are not yet well resolved, the structural support also remains tentative. Some of the features that turned out to be of interest in the present study had not previously been considered in earlier supraordinal studies. The strongest floral structural support is for malvids (Brassicales, Malvales, Sapindales), which reflects the strong support of phylogenetic analyses. Somewhat less structurally supported are the COM (Celastrales, Oxalidales, Malpighiales) and the nitrogen-fixing (Cucurbitales, Fagales, Fabales, Rosales) clades of fabids, which are both also only weakly supported in phylogenetic analyses. The sister pairs, Cucurbitales plus Fagales, and Malvales plus Sapindales, are structurally only weakly supported, and for the entire fabids there is no clear support by the present floral structural data. However, an additional grouping, the COM clade plus malvids, shares some interesting features but does not appear as a clade in phylogenetic analyses. Thus it appears that the deepest split within eurosids- that between fabids and malvids - in molecular phylogenetic analyses (however weakly supported) is not matched by the present structural data. Features of ovules including thickness of integuments, thickness of nucellus, and degree of ovular curvature, appear to be especially interesting for higher level relationships and should be further explored.

W. Mennega Nationaal Herbarium Nederland, Utrecht University branch, Heidelberglaan 2, 3584 es Utrecht, The Netherlands SUMMARY The wood anatomy was studied of 82 species from 34 out of 54 genera in the subfamily Euphorbioideae, covering all five tribes recognized in this subfamily. In general the woods show a great deal of similarity. They are charac­ terized by a relative paucity of vessels, often arranged in short to long, dumbbell-shaped or twin, radial multiples, and by medium-sized to large intervessel pits; fibres often have gelatinous walls; parenchyma apotracheal in short, wavy, narrow bands and diffuse-in-aggregates; mostly uni- or only locally biseriate rays, strongly heterocellular (except Hippomane, Hura and Pachystroma). Cell contents, either silica or crystals, or both together, are nearly always present and often useful in distinguishing between genera. Radiallaticifers were noticed in most genera, though they are scarce and difficult to trace. The laticifers are generally not surrounded by special cells, except in some genera of the subtribe Euphorbiinae where radiallaticifers are comparatively frequent and conspicuous. Three ofthe five tribes show a great deal of conformity in their anatomy. Stomatocalyceae, however, stand apart from the rest by the combination of the scarcity of vessels, and mostly biseriate, vertically fused and very tall rays. Within Euphorbieae the subtribe Euphorbiinae shows a greater vari­ ation than average, notably in vessel pitting, the frequent presence of two­ celled parenchyma strands, and in size and frequency of the laticifers.
