Abstract Background: The Vitaceae (grape) is an economically important family of angiosperms whose phylogenetic placement is currently unresolved. Recent phylogenetic analyses based on one to several genes have suggested several alternative placements of this family, including sister to Caryophyllales, asterids, Saxifragales, Dilleniaceae or to rest of rosids, though support for these different results has been weak. There has been a recent interest in using complete chloroplast genome sequences for resolving phylogenetic relationships among angiosperms. These studies have clarified relationships among several major lineages but they have also emphasized the importance of taxon sampling and the effects of different phylogenetic methods for obtaining accurate phylogenies. We sequenced the complete chloroplast genome of Vitis vinifera and used these data to assess relationships among 27 angiosperms, including nine taxa of rosids. Results: The Vitis vinifera chloroplast genome is 160,928 bp in length, including a pair of inverted repeats of 26,358 bp that are separated by small and large single copy regions of 19,065 bp and 89,147 bp, respectively. The gene content and order of Vitis is identical to many other unrearranged angiosperm chloroplast genomes, including tobacco. Phylogenetic analyses using maximum parsimony and maximum likelihood were performed on DNA sequences of 61 protein-coding genes for two datasets with 28 or 29 taxa, including eight or nine taxa from four of the seven currently recognized major clades of rosids. Parsimony and likelihood phylogenies of both data sets provide strong support for the placement of Vitaceae as sister to the remaining rosids. However, the position of the Myrtales and support for the monophyly of the eurosid I clade differs between the two data sets and the two methods of analysis. In parsimony analyses, the inclusion of Gossypium is necessary to obtain trees that support the monophyly of the eurosid I clade. However, maximum likelihood analyses place Cucumis as sister to the Myrtales and therefore do not support the monophyly of the eurosid I clade. Conclusion: Phylogenies based on DNA sequences from complete chloroplast genome sequences provide strong support for the position of the Vitaceae as the earliest diverging lineage of rosids. Our phylogenetic analyses support recent assertions that inadequate taxon sampling and incorrect model specification for concatenated multi-gene data sets can mislead phylogenetic inferences when using whole chloroplast genomes for phylogeny reconstruction.

Single and multi-gene phylogenies of rosids have identified seven major clades, however, relation- ships among these clades remain unresolved [13-16]. One of these unresolved clades includes the Vitaceae, which includes grape, an important crop plant. The phylogenetic position of Vitaceae has been controversial for many years. Some previous classifications place the family within the Rhamnales in the subclass Rosidae [17]. More recent molecular phylogenies based on one to four genes provided weak support for the placement of Vitaceae sister to the Caryophylales [18], asterids [18], Saxifragales [14], Dilleniaceae [19], or to the rosids [14-16]. Thus, the phy- logenetic relationship of the grape family to core eudicots remains unresolved.

Broad-scale phylogenetic analyses of the angiosperms and of the Asteridae have failed to confidently resolve relationships among the major lineages of the campanulid Asteridae (i.e., the euasterid II of APG II, 2003). To address this problem we assembled presently available sequences for a core set of 50 taxa, representing the diver- sity of the four largest lineages (Apiales, Aquifoliales, Asterales, Dipsacales) as well as the smaller “unplaced” groups (e.g., Bruniaceae, Paracryphiaceae, Columelliaceae). We constructed four data matrices for phylogenetic analysis: a chloroplast coding matrix (atpB, matK, ndhF, rbcL), a chloroplast non-coding matrix (rps16 intron, trnT-F region, trnV-atpE IGS), a combined chloroplast dataset (all seven chloroplast regions), and a combined genome matrix (seven chloroplast regions plus 18S and 26S rDNA). Bayesian analyses of these datasets using mixed substitution models produced often well-resolved and supported trees.

    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page.

  • Resolution of Deep Angiosperm Phylogeny Using Conserved Nuclear Genes and Estimates of Early Divergence Times
    ARTICLE Received 24 Mar 2014 | Accepted 11 Aug 2014 | Published 24 Sep 2014 DOI: 10.1038/ncomms5956 OPEN Resolution of deep angiosperm phylogeny using conserved nuclear genes and estimates of early divergence times Liping Zeng1, Qiang Zhang2, Renran Sun1, Hongzhi Kong3, Ning Zhang1,4 & Hong Ma1,5 Angiosperms are the most successful plants and support human livelihood and ecosystems. Angiosperm phylogeny is the foundation of studies of gene function and phenotypic evolution, divergence time estimation and biogeography. The relationship of the five divergent groups of the Mesangiospermae (B99.95% of extant angiosperms) remains uncertain, with multiple hypotheses reported in the literature. Here transcriptome data sets are obtained from 26 species lacking sequenced genomes, representing each of the five groups: eudicots, monocots, magnoliids, Chloranthaceae and Ceratophyllaceae. Phylogenetic analyses using 59 carefully selected low-copy nuclear genes resulted in highly supported relationships: sisterhood of eudicots and a clade containing Chloranthaceae and Ceratophyllaceae, with magnoliids being the next sister group, followed by monocots. Our topology allows a re-examination of the evolutionary patterns of 110 morphological characters. The molecular clock estimates of Mesangiospermae diversification during the late to middle Jurassic correspond well to the origins of some insects, which may have been a factor facilitating early angiosperm radiation. 1 State Key Laboratory of Genetic Engineering and Collaborative Innovation Center for Genetics and Development, Ministry of Education Key Laboratoryof Biodiversity Sciences and Ecological Engineering, Institute of Plant Biology, Institute of Biodiversity Science, Center for Evolutionary Biology, School of Life Sciences, Fudan University, 220 Handan Road, Yangpu District, Shanghai 200433, China. 2 Guangxi Institute of Botany, Guangxi Zhuang Autonomous Region and the Chinese Academy of Sciences, Guilin 541006, China.

  • Vestured Pits in Wood of Onagraceae: Correlations with Ecology, Habit, and Phylogeny1
    VESTURED PITS IN WOOD OF Sherwin Carlquist2 and Peter H. Raven3 ONAGRACEAE: CORRELATIONS WITH ECOLOGY, HABIT, AND PHYLOGENY1 ABSTRACT All Onagraceae for which data are available have vestured pits on vessel-to-vessel pit pairs. Vestures may also be present in some species on the vessel side of vessel-to-ray pit pairs. Herbaceous Onagraceae do not have fewer vestures, although woods with lower density (Circaea L. and Oenothera L.) have fewer vestures. Some Onagraceae from drier areas tend to have smaller vessel pits, and on that account may have fewer vestures (Epilobium L. and Megacorax S. Gonz´alez & W. L. Wagner). Pit apertures as seen on the lumen side of vessel walls are elliptical, occasionally oval, throughout the family. Vestures are predominantly attached to pit aperture margins. As seen from the outer surfaces of vessels, vestures may extend across the pit cavities. Vestures are usually absent or smaller on the distal portions of pit borders (except for Ludwigia L., which grows consistently in wet areas). Distinctive vesture patterns were observed in the several species of Lopezia Cav. and in Xylonagra Donn. Sm. & Rose. Vestures spread onto the lumen-facing vessel walls of Ludwigia octovalvis (Jacq.) P. H. Raven. Although the genera are presented here in the sequence of a recent molecular phylogeny of Onagraceae, ecology and growth forms are more important than evolutionary relationships with respect to abundance, degree of grouping, and morphology of vestured pits. Designation of vesture types is not warranted based on the distribution of named types in Onagraceae and descriptive adjectives seem more useful, although more data on vesturing in the family are needed before patterns of diversity and their extent can be fully ascertained.

    UNCORRECTED PAGE PROOFS An Overview of Green Plant Phylogeny he word plant is commonly used to refer to any auto- trophic eukaryotic organism capable of converting light energy into chemical energy via the process of photosynthe- sis. More specifically, these organisms produce carbohydrates from carbon dioxide and water in the presence of chlorophyll inside of organelles called chloroplasts. Sometimes the term plant is extended to include autotrophic prokaryotic forms, especially the (eu)bacterial lineage known as the cyanobacteria (or blue- green algae). Many traditional botany textbooks even include the fungi, which differ dramatically in being heterotrophic eukaryotic organisms that enzymatically break down living or dead organic material and then absorb the simpler products. Fungi appear to be more closely related to animals, another lineage of heterotrophs characterized by eating other organisms and digesting them inter- nally. In this chapter we first briefly discuss the origin and evolution of several separately evolved plant lineages, both to acquaint you with these important branches of the tree of life and to help put the green plant lineage in broad phylogenetic perspective. We then focus attention on the evolution of green plants, emphasizing sev- eral critical transitions.

  • Diversity in Host Preference of Rotylenchus Spp. Y.S
    International Journal of Science, Environment ISSN 2278-3687 (O) and Technology, Vol. 7, No 5, 2018, 1786 – 1793 2277-663X (P) DIVERSITY IN HOST PREFERENCE OF ROTYLENCHUS SPP. Y.S. Rathore Principal Scientist (Retd.), Indian Institute of Pulses Research, Kanpur -208024 (U.P.) E-mail: [email protected] Abstract: Species of the genus Rotylenchus are ecto- or semi-endo parasites and feed on roots of their host plants. In the study it was found that 50% species of Rotylenchus were monophagous and mostly on plants in the clade Rosids followed by monocots, Asterids and gymnosperms. In general, Rosids and Asterids combined parasitized more than 50% host species followed by monocots. Though food preference was species specific but by and large woody plants were preferred from very primitive families like Magnoliaceae and Lauraceae to representatives of advanced families. Woody plants like pines and others made a substantial contribution in the host range of Rotylenchus. Maximum number of Rotylenchus species harboured plants in families Poaceae (monocots), Rosaceae (Rosids) and Oleaceae (Asterids) followed by Fabaceae, Fagaceae, Asteraceae and Pinaceae. It is, therefore, suggested that agricultural crops should be grown far away from wild vegetation and forest plantations. Keywords: Rotylenchus, Magnoliids, Rosids, Asterids, Gymnosperms, Host preference. INTRODUCTION Species of the genus Rotylenchus (Nematoda: Haplolaimidae) are migratory ectoparasites and browse on the surface of roots.
