  • biological control in the United States of America
    2013
    Co-Authors: Brian G. Rector, Radmila U. Petanović

  • Host range testing and biology of Abia sericea (Cimbicidae), a candidate for biological control of invasive teasels (Dipsacus spp.) in North America
    Journal of Hymenoptera Research, 2012
    Co-Authors: Vili Harizanova, Atanaska Stoeva, Brian G. Rector
    Abstract:

    Invasive teasels (Dipsacus spp., Dipsacaceae) are widespread in the USA, being present in 43 states and listed as noxious in five. The cimbicid sawfly Abia sericea (Linne, 1767) is under evaluation as a potential agent for classical biological control of teasels. The host range, biology, and life history of this insect were studied under laboratory conditions and in common garden experiments from 2006–2010 at the Agricultural University of Plovdiv, Bulgaria in order to determine if this biocontrol candidate justified the expense of further testing under quarantine conditions in the USA. In the laboratory, potted plants from twelve plant species belonging to seven families were tested in choice tests of oviposition and feeding. Eggs were laid only on D. laciniatus and D. fullonum plants with only one exception, on Valeriana officinalis, although the larvae that hatched from the latter did not feed on that plant. Larval feeding was observed only on D. laciniatus, Knautia arvensis, and Scabiosa ochroleuca, all in the family Dipsacaceae, which has no species native to the New World nor any of economic importance. In common garden tests into which adults and third- and fourth-instar larvae were released in separate tests, eggs were laid and larvae fed only on D. laciniatus. The results of these experiments indicate that A. sericea has a narrow host range, most likely limited to Dipsacus species, and a few other Dipsacaceae and that further pre-release studies in a US quarantine are warranted.

  • A new species of Aculops (Acari: Prostigmata: Eriophyidae) from Serbia on Dipsacus laciniatus L. (Dipsacaceae), a weed target of classical biological control in the United States of America
    Zootaxa, 2012
    Co-Authors: Brian G. Rector, Radmila U. Petanović
    Abstract:

    A new eriophyoid mite species, Aculops orlovacae n. sp. (Acari: Prostigmata: Eriophyidae) collected from Dipsacus laciniatus L. (Dipsacaceae) in northern Serbia, is described and illustrated, including digital micrographs depicting key morphological characters. Differential diagnosis is provided in comparison with Aculops salixis Xue, Song et Hong, Aculops rhodensis (Keifer), Aculops hussongi Keifer and Aculops oblongus (Nalepa). This is the first eriophyoid mite species in the genus Aculops described from a host plant in the family Dipsacaceae and it is only the second eriophyoid known from a host species in the genus Dipsacus L. This mite was found during surveys for natural enemies of Dipsacus spp., as part of a classical biological control program.

  • Prospects for biological control of teasels, Dipsacus spp., a new target in the United States
    Biological Control, 2005
    Co-Authors: Brian G. Rector, Vili Harizanova, René Sforza, Tim Widmer, Robert N. Wiedenmann
    Abstract:

    Two closely related teasels (Dipsacales: Dipsacaceae, Dipsacus spp.) of European origin have become invasive weeds in the United States. Common teasel (Dipsacus fullonum L.) and cutleaf teasel (Dipsacus laciniatus L.) have likely been in North America for more than two centuries, having been introduced along with cultivated teasel [D. sativus (L.) Honckney], an obsolete crop plant. There are few records of American insects or pathogens attacking Dipsacus spp. Invasive teasels have recently begun to spread rapidly throughout much of their current range, for reasons that are not yet known. Common and/or cut-leaf teasel have been listed as noxious in five US states and as invasive in 12 other states and four national parks. Because the family Dipsacaceae is an exclusively Old World family, classical biological control is an important component of the overall management strategy of this weed in the US. Field surveys for natural enemies of D. fullonum and D. laciniatus in their native ranges and literature reviews of natural enemies of plants in the family Dipsacaceae have yielded 102 species of insects in six orders, as well as 27 fungi from 10 orders, three mites, one nematode, and two viruses. Due to the biennial nature of these weeds, a strategy to assign highest priority to biological control candidates attacking first-year (rosette) plants has been established. Candidates selected for further study based on this strategy include Chromatomyia ramosa (Hendel) (Diptera: Agromyzidae), Longitarsus strigicollis Wollaston (Coleoptera: Chrysomelidae), Epitrimerus knautiae Liro (Acarina: Eriophyiidae), Euphydryas desfontainii (Godart) (Lepidoptera: Nymphalidae), Erysiphe knautiae Duby (Erysiphales: Erysiphaceae), and Sphaerotheca dipsacearum (Tul. and C. Tul.) (Erysiphales: Erysiphaceae).

  • Diversification of CYCLOIDEA-like genes in Dipsacaceae (Dipsacales): implications for the evolution of capitulum inflorescences
    BMC Evolutionary Biology, 2011
    Co-Authors: Sara E. Carlson, Dianella G. Howarth, Michael J. Donoghue
    Abstract:

    Background CYCLOIDEA (CYC)-like genes have been implicated in the development of capitulum inflorescences (i.e. flowering heads) in Asteraceae, where many small flowers (florets) are packed tightly into an inflorescence that resembles a single flower. Several rounds of duplication of CYC-like genes have occurred in Asteraceae, and this is hypothesized to be correlated with the evolution of the capitulum, which in turn has been implicated in the evolutionary success of the group. We investigated the evolution of CYC-like genes in Dipsacaceae (Dipsacales), a plant clade in which capitulum inflorescences originated independently of Asteraceae. Two main inflorescence types are present in Dipsacaceae: (1) radiate species contain two kinds of floret within the flowering head (disk and ray), and (2) discoid species contain only disk florets. To test whether a dynamic pattern of gene duplication, similar to that documented in Asteraceae, is present in Dipsacaceae, and whether these patterns are correlated with different inflorescence types, we inferred a CYC-like gene phylogeny for Dipsacaceae based on representative species from the major lineages.

  • Phylogenetic relationships, taxonomy, and morphological evolution in Dipsacaceae (Dipsacales) inferred by DNA sequence data
    Taxon, 2009
    Co-Authors: Sara E. Carlson, Veronika Mayer, Michael J. Donoghue
    Abstract:

    A phylogenetic study of Dipsacaceae, a Mediterranean-centered clade in the Dipsacales, was conducted using nuclear ITS and three chloroplast markers (atpB-rbcL, trnL-trnF, trnS UGA- trnG GCC ). This is the first molecular study to assess Dipsacaceae phylogeny in detail, and includes representatives from all major subclades. Maximum parsimony, maximum likelihood, and Bayesian analyses were carried out on the ITS and plastid datasets separately and in combination. For the most part, the ITS and plastid datasets resulted in similar topologies, and the combined data yielded a well-resolved estimate of Dipsacaceae phylogeny. A small Asian clade composed of Bassecoia and Pterocephalodes hookeri is resolved as sister to the rest of Dipsacaceae. Scabioseae s.str. (Scabiosa, Sixalix, Pterocephalus s.str., Lomelosia, Pycnocomon) and a "Dipknautid" clade (Dipsacus, Cephalaria, Knautia, Pterocephalidum, Succisa, Succisella, Pseudoscabiosa) form the two major lineages within Dipsacaceae. Most of the previously recognized genera are recovered as monophyletic, with the exception of Pycnocomon, which is nested within Lomelosia. We discuss the taxonomic implications of these results and their significance for understanding character evolution, particularly of the epicalyx in relation to seed dispersal.

  • Phylogeny and biogeography of Morinaceae (Dipsacales) based on nuclear and chloroplast DNA sequences
    Organisms Diversity & Evolution, 2004
    Co-Authors: Charles D. Bell, Michael J. Donoghue
    Abstract:

    Abstract The Morinaceae (Dipsacales) contains 13 species placed in Acanthocalyx, Cryptothladia or Morina, and is distributed from the mountains of southeastern Europe through the Himalayas to the Qinghai-Tibetan Plateau, mainly in alpine habitats. Sequence data from two chloroplast regions (the trnK intron and the trnL-F region) and the internal transcribed spacer (ITS) region of nuclear ribosomal DNA were used to infer phylogenetic relationships of Morinaceae and related Dipsacales. Both the nuclear and chloroplast datasets, as well as the combined data, provide strong support for relationships within the Valerina clade, placing Morinaceae as the sister group of a clade containing Valerianaceae and Dipsacaceae plus Triplostegia. The Morinaceae, Acanthocalyx, Cryptothladia, and a clade containing Morina and Cryptothladia, are all supported as monophyletic. However, Morina was found to be paraphyletic in several of our analyses, with Morina longifolia more closely related to Cryptothladia than to other Morina species. There is some evidence that Morina longifolia produces cleistogamous flowers, as do Cryptothladia species. Dispersal-vicariance analyses support the view that Valerina radiated initially within Asia, with subsequent movement into Europe in Morinaceae, Dipsacaceae, and Valerianaceae, and into the New World in Valerianaceae. For Morinaceae, as for a number of plant groups, the Brahmaputra river drainage marks a significant biogeographic divide, although this has been spanned within Acanthocalyx and the Morina-Cryptothladia lineage.

  • phylogeny and phylogenetic taxonomy of dipsacales, with special reference to sinadoxa and tetradoxa (adoxaceae)
    2001
    Co-Authors: Patrick A. Reeves, Michael J. Donoghue, Torsten Eriksson, Richard G. Olmstead
    Abstract:

    To further clarify phylogenetic relationships within Dipsacales,we analyzed new and previously published rbcL sequences, alone and in combination with morphological data. We also examined relationships within Adoxaceae using rbcL and nuclear ribosomal internal transcribed spacer (ITS) sequences. We conclude from these analyses that Dipsacales comprise two major lineages:Adoxaceae and Caprifoliaceae (sensu Judd et al.,1994), which both contain elements of traditional Caprifoliaceae. Within Adoxaceae, the following relationships are strongly supported: (Viburnum (Sambucus (Sinadoxa (Tetradoxa, Adoxa)))). Combined analyses of C ap ri foliaceae yield the fo l l ow i n g : ( C ap ri folieae (Diervilleae (Linnaeeae (Morinaceae (Dipsacaceae (Triplostegia, Valerianaceae)))))). On the basis of these results we provide phylogenetic definitions for the names of several major clades. Within Adoxaceae, Adoxina refers to the clade including Sinadoxa, Tetradoxa, and Adoxa. This lineage is marked by herbaceous habit, reduction in the number of perianth parts,nectaries of multicellular hairs on the perianth,and bifid stamens. The clade including Morinaceae, Valerianaceae, Triplostegia, and Dipsacaceae is here named Valerina. Probable synapomorphies include herbaceousness,presence of an epicalyx (lost or modified in Valerianaceae), reduced endosperm,and distinctive chemistry, including production of monoterpenoids. The clade containing Valerina plus Linnaeeae we name Linnina. This lineage is distinguished by reduction to four (or fewer) stamens, by abortion of two of the three carpels,and possibly by supernumerary inflorescences bracts.

  • Phylogenetic relationships of Dipsacales based on rbcl sequences
    Annals of the Missouri Botanical Garden, 1992
    Co-Authors: Michael J. Donoghue, Richard G. Olmstead, James F. Smith, Jeffrey D. Palmer
    Abstract:

    Nucleotide sequences of the chloroplast gene rbcL were obtained from Lonicera, Sambucus, Adoxa, and Cornus. Phylogenetic analyses of these sequences, along with previously sequenced Dipsacales and placeholders for other Asteridae and Rosidae, lead to the following conclusions: (1) the genera of Caprifoliaceae (in any traditional sense) do not form a monophyletic group; (2) Symphoricarpos and Lonicera (representing Caprifoliaceae sens. str.) are related and are united with Valerianaceae and Dipsacaceae; and (3) Adoxa and Sambucus are directly linked and are possibly related to Viburnum

  • APORTES FITOQUIMICOS A LA SISTEMATICA DE LA FAMILIA Dipsacaceae PHYTOCHEMICALS CONTRIBUTIONS TO THE Dipsacaceae SYSTEMATIC
    2014
    Co-Authors: Diego Rodríguez-hernández, Antonio J. Demuner, Alberto De J. Oliveros-bastidas
    Abstract:

    This work is part of a review of the Dipsacaceae family and its contributions. The chemistry is diversified to 89 species, such us glycosides triterpenes, flavonoids, iridoids and phenylpropanoids that are considered as taxonomy indicators, due its occurrence number and structural diversity. In fact, the analysis of the correlations between chemistry parameters about the basis of selected seconday metabolities with morphological parameters permits the reorganization of the systematic. Indeed, phenypropanol derivatives served as markers of Morinaceae, as well as absence of flavonoids permitted the recognition of Triplostegiaceae. Dipsacaceae, Morinaceae and Triplostegiaceae families presents differences in the production of its secondary metabolites, confirming the recognition of two segregate families from the Dipsacaceae and their systematic from a phytochemical point of view.

  • APORTES FITOQUIMICOS A LA SISTEMATICA DE LA FAMILIA Dipsacaceae
    Executive Business School, 2014
    Co-Authors: Diego Rodríguez-hernández, Antonio J. Demuner, Amalyn Nain-perez, Luiz C.a. Barbosa, Alberto De J. Oliveros-bastidas
    Abstract:

    Este trabajo enmarca una revisión fitoquímica de la familia Dipsacaceae y los aportes a su sistemática. La química es diversificada para las 89 especies consideradas, triterpenos glicosidados, flavonoides, iridoides y fenil propanoides fueron seleccionados como indicadores taxonómicos, debidos no solo al número de ocurrencia, sino también a la diversidad estructural. El análisis de las correlaciones entr e los parámetros químicos sobre la base de los metabolitos secundarios seleccionados, consigo mismo y con los parámetros morfológicos, permiten en parte la reorganización de la sistemática planteada hasta hoy. Conjuntamente los derivados del fenil propano l sirvieron como marcadores para el reconocimiento de Morinaceae, así como la ausencia de flavonoides permitió el reconocimiento de Triplostegiacea. Quimiotaxonomicante, las familias Dipsacaceae, Morinaceae y Triplostegiaceae, presentan diferencias marcada s en la producción de sus respectivos metabolitos secundarios, confirmado el reconocimiento de ambas familias segregadas de las Dipsacaceae y en parte su sistemática desde un punto de vista fitoquímico
