Bayesian inference of recent migration rates using multilocus genotypes. (1/35)

A new Bayesian method that uses individual multilocus genotypes to estimate rates of recent immigration (over the last several generations) among populations is presented. The method also estimates the posterior probability distributions of individual immigrant ancestries, population allele frequencies, population inbreeding coefficients, and other parameters of potential interest. The method is implemented in a computer program that relies on Markov chain Monte Carlo techniques to carry out the estimation of posterior probabilities. The program can be used with allozyme, microsatellite, RFLP, SNP, and other kinds of genotype data. We relax several assumptions of early methods for detecting recent immigrants, using genotype data; most significantly, we allow genotype frequencies to deviate from Hardy-Weinberg equilibrium proportions within populations. The program is demonstrated by applying it to two recently published microsatellite data sets for populations of the plant species Centaurea corymbosa and the gray wolf species Canis lupus. A computer simulation study suggests that the program can provide highly accurate estimates of migration rates and individual migrant ancestries, given sufficient genetic differentiation among populations and sufficient numbers of marker loci.  (+info)

Microsatellite allele sizes: a simple test to assess their significance on genetic differentiation. (2/35)

The mutation process at microsatellite loci typically occurs at high rates and with stepwise changes in allele sizes, features that may introduce bias when using classical measures of population differentiation based on allele identity (e.g., F(ST), Nei's Ds genetic distance). Allele size-based measures of differentiation, assuming a stepwise mutation process [e.g., Slatkin's R(ST), Goldstein et al.'s (deltamu)(2)], may better reflect differentiation at microsatellite loci, but they suffer high sampling variance. The relative efficiency of allele size- vs. allele identity-based statistics depends on the relative contributions of mutations vs. drift to population differentiation. We present a simple test based on a randomization procedure of allele sizes to determine whether stepwise-like mutations contributed to genetic differentiation. This test can be applied to any microsatellite data set designed to assess population differentiation and can be interpreted as testing whether F(ST) = R(ST). Computer simulations show that the test efficiently identifies which of F(ST) or R(ST) estimates has the lowest mean square error. A significant test, implying that R(ST) performs better than F(ST), is obtained when the mutation rate, mu, for a stepwise mutation process is (a) >/= m in an island model (m being the migration rate among populations) or (b) >/= 1/t in the case of isolated populations (t being the number of generations since population divergence). The test also informs on the efficiency of other statistics used in phylogenetical reconstruction [e.g., Ds and (deltamu)(2)], a nonsignificant test meaning that allele identity-based statistics perform better than allele size-based ones. This test can also provide insights into the evolutionary history of populations, revealing, for example, phylogeographic patterns, as illustrated by applying it on three published data sets.  (+info)

Altered gene expression in three plant species in response to treatment with Nep1, a fungal protein that causes necrosis. (3/35)

Nep1 is an extracellular fungal protein that causes necrosis when applied to many dicotyledonous plants, including invasive weed species. Using transmission electron microscopy, it was determined that application of Nep1 (1.0 micro g mL(-)(1), 0.1% [v/v] Silwet-L77) to Arabidopsis and two invasive weed species, spotted knapweed (Centaurea maculosa) and dandelion (Taraxacum officinale), caused a reduction in the thickness of the cuticle and a breakdown of chloroplasts 1 to 4 h after treatment. Membrane breakdown was most severe in cells closest to the surface of application. Differential display was used to isolate cDNA clones from the three species showing differential expression in response to Nep1 treatment. Differential gene expression was observed for a putative serpin (CmSER-1) and a calmodulin-like (CmCAL-1) protein from spotted knapweed, and a putative protein phosphatase 2C (ToPP2C-1) and cytochrome P-450 (ToCYP-1) protein from dandelion. In addition, differential expression was observed for genes coding for a putative protein kinase (AtPK-1), a homolog (AtWI-12) of wound-induced WI12, a homolog (AtLEA-1) of late embryogenesis abundant LEA-5, a WRKY-18 DNA-binding protein (AtWRKY-18), and a phospholipase D (AtPLD-1) from Arabidopsis. Genes showing elevated mRNA levels in Nep1-treated (5 micro g mL(-)(1), 0.1% [v/v] Silwet-L77) leaves 15 min after Nep1 treatment included CmSER-1 and CmCAL-1 for spotted knapweed, ToCYP-1 and CmCAL-1 for dandelion, and AtPK-1, AtWRKY-18, AtWI-12, and AtLEA-1 for Arabidopsis. Levels of mRNA for AtPLD-1 (Arabidopsis) and ToPP2C-1 (dandelion) decreased rapidly in Silwet-L77-treated plants between 15 min and 4 h of treatment, but were maintained or decreased more slowly over time in Nep1-treated (5 micro g mL(-)(1), 0.1% [v/v] Silwet-L77) leaves. In general, increases in mRNA band intensities were in the range of two to five times, with only ToCYP-1 in dandelion exceeding an increase of 10 times. The identified genes have been shown to be involved or are related to gene families that are involved in plant stress responses, including wounding, drought, senescence, and disease resistance.  (+info)

Allelopathy and exotic plant invasion: from molecules and genes to species interactions. (4/35)

Here we present evidence that Centaurea maculosa (spotted knapweed), an invasive species in the western United States, displaces native plant species by exuding the phytotoxin (-)-catechin from its roots. Our results show inhibition of native species' growth and germination in field soils at natural concentrations of (-)-catechin. In susceptible species such as Arabidopsis thaliana, the allelochemical triggers a wave of reactive oxygen species (ROS) initiated at the root meristem, which leads to a Ca2+ signaling cascade triggering genome-wide changes in gene expression and, ultimately, death of the root system. Our results support a "novel weapons hypothesis" for invasive success.  (+info)

Inheritance of resistance to clopyralid and picloram in yellow starthistle (Centaurea solstitialis L.) is controlled by a single nuclear recessive gene. (5/35)

The noxious weed yellow starthistle (Centaurea solstitialis L.) can be controlled effectively at the seedling stage with foliar application of the auxinic herbicides picloram or clopyralid. Although resistance to these herbicides is rare, a yellow starthistle biotype resistant to picloram and cross-resistant to clopyralid was observed in 1989 near Dayton, WA, in a pasture that had been subjected to intensive picloram selective pressure. Our objective was to determine the mode of inheritance for this resistance trait. Transmission of the resistant phenotype was monitored in reciprocal F(1) crosses between susceptible (SCI) and resistant (RDW) plants, their testcross and pseudo-F(2) progeny. Progeny from all crosses, as well as RDW and SCI seedlings of original populations, were sprayed with picloram or clopyralid to distinguish between susceptible and resistant individuals. All F(1) progeny were susceptible to both herbicides, indicating that the resistance trait was of nuclear origin and recessive in nature. Segregation of the resistant phenotype among pseudo-F(2) and testcross progeny of F(1) genotypes demonstrated monofactorial inheritance (P >.25) for resistance to both herbicides. The conclusion that resistance is conferred by a single recessive allele is consistent with the observation that no other picloram-resistant yellow starthistle populations have been identified in the area since picloram selection pressure was abated.  (+info)

Realistic species losses disproportionately reduce grassland resistance to biological invaders. (6/35)

Consequences of progressive biodiversity declines depend on the functional roles of individual species and the order in which species are lost. Most studies of the biodiversity-ecosystem functioning relation tackle only the first of these factors. We used observed variation in grassland diversity to design an experimental test of how realistic species losses affect invasion resistance. Because entire plant functional groups disappeared faster than expected by chance, resistance declined dramatically with progressive species losses. Realistic biodiversity losses, even of rare species, can thus affect ecosystem processes far more than indicated by randomized-loss experiments.  (+info)

Fine-scale genetic structure and gene dispersal in Centaurea corymbosa (Asteraceae). II. Correlated paternity within and among sibships. (7/35)

The fine-scale pattern of correlated paternity was characterized within a population of the narrow-endemic model plant species, Centaurea corymbosa, using microsatellites and natural progeny arrays. We used classical approaches to assess correlated mating within sibships and developed a new method based on pairwise kinship coefficients to assess correlated paternity within and among sibships in a spatio-temporal perspective. We also performed numerical simulations to assess the relative significance of different mechanisms promoting correlated paternity and to compare the statistical properties of different estimators of correlated paternity. Our new approach proved very informative to assess which factors contributed most to correlated paternity and presented good statistical properties. Within progeny arrays, we found that about one-fifth of offspring pairs were full-sibs. This level of correlated mating did not result from correlated pollen dispersal events (i.e., pollen codispersion) but rather from limited mate availability, the latter being due to limited pollen dispersal distances, the heterogeneity of pollen production among plants, phenological heterogeneity and, according to simulations, the self-incompatibility system. We point out the close connection between correlated paternity and the "TwoGener" approach recently developed to infer pollen dispersal and discuss the conditions to be met when applying the latter.  (+info)

Centaurea revisited: A molecular survey of the Jacea group. (8/35)

BACKGROUND AND AIMS: The genus Centaurea has traditionally been considered to be a complicated taxon. No attempt at phylogenetic reconstruction has been made since recent revisions in circumscription, and previous reconstructions did not include a good representation of species. A new molecular survey is thus needed. METHODS: Phylogenetic analyses were conducted using sequences of the internal transcribed spacers (ITS) 1 and 2 and the 5.8S gene. Parsimony and Bayesian approaches were used. KEY RESULTS: A close correlation between geography and the phylogenetic tree based on ITS sequences was found in all the analyses, with three main groups being resolved: (1) comprising the most widely distributed circum-Mediterranean/Eurosiberian sections; (2) the western Mediterranean sections; and (3) the eastern Mediterranean and Irano-Turanian sections. The results show that the sectional classification in current use needs major revision, with many old sections being merged into larger ones. A large polytomy in the eastern Mediterranean clade suggests a rapid and recent speciation in this group. Some inconsistencies between morphology and molecular phylogeny may indicate that hybridization has played a major role in the evolution of the genus. CONCLUSIONS: Phylogenetic analysis of ITS has been useful in identifying the major lineages in the group, and unraveling many inconsistencies in the sectional classification. However, most recent groups in the eastern Mediterranean clade are not resolved and reticulation in the western Mediterranean group of sections makes phylogenetic relationships within these two groups somewhat obscure.  (+info)

Centaurea solstitialis L. (yellow starthistle) is an annual noxious weed that currently infests millions of acres of rangelands, non-cultivated and natural areas in the Western USA. It displaces native plant communities reducing plant diversity and forage production for livestock and wildlife. Aceria solstitialis L. is an eriophyoid mite found exclusively in association with C. solstitialis in Turkey and Bulgaria. This mite damages bolting plants causing stunting, leaf curling and incomplete flower development. During 2008 and 2009, two open field tests were conducted in Bulgaria, to study the mites dispersal behavior and host range. The experiments were conducted on plots of 100 m2 at the experimental field of Agricultural University of Plovdiv. Five plant species were included in the experiment: C. solstitialis (infested and not-infested), C. diffusa Burm.f. .C. cyanus L., Carthamus tinctorius Mohler, Roth, Schmidt & Boudreaux, and Cynara scolymus L.

The largest impact of humans on diffuse knapweed is certainly due to our efforts in controlling and eradicating its invasive populations. The several methods outlined in the control section represent a small sample of literally hundreds of approaches being tried with varying levels of effectiveness. Besides reducing the spread of diffuse knapweed, we are also providing selective pressure against the individuals that cannot withstand a certain method of control. Selective pressure, given sufficient time, can cause the adaptation or evolution of invasive species such as diffuse knapweed. If an individual diffuse knapweed plant survives control efforts because of a trait it possesses, its progeny will make up a greater portion of the population than the plants that succumbed to the control.. The success of diffuse knapweed must be attributed to a combination of several mechanisms. Its invasiveness is due to a mix of allelopathy, ERH and superior resource competition. However, the most importance ...
Chaetorellia acrolophi is a species of tephritid fruit fly known as the knapweed peacock fly. It is used as an agent of biological pest control against noxious knapweeds, especially spotted knapweed (Centaurea maculosa).. The adult fly is light greenish brown with brown-banded wings and iridescent green eyes. It is 3 to 5 millimeters long.external image The female lays about 70 eggs beneath the bracts on immature flower heads. When the larva emerges from the egg a few days later it burrows into the flower head and feeds on the developing florets. As the larva grows it begins to feed on the developing seeds, often consuming the entire contents of the flower head during its two-week larval stage. It pupates inside the empty flower head.. This fly is native to Europe. It was first released as a knapweed biocontrol in the 1990s in Montana, and it is currently established in much of the western United States. It is host-specific to invasive knapweeds, preferring spotted knapweed, and has not been ...
Pollinators and pollination services are under threat globally, and invasive plants have been implicated in their decline. Results of previous studies suggest that consequences of invasion for pollinators and plant-pollinator interactions are context specific. Investigating factors such as the density of an invasive plant and its phenology may provide a nuanced understanding of invasive species impacts. We conducted a 2-yr study in Montana to investigate how local pollinator abundance, richness, community composition, and visitation patterns varied with invasive Centaura stoebe density and phenology, and whether C. stoebe altered the reproduction of a co-flowering native plant, Heterotheca villosa, through changes in pollinator visitation. In an observational study, we found that during its peak bloom in August, Centaurea stoebe provided abundant floral resources to late-season pollinators. However, prior to C. stoebe bloom, native floral density and pollinator abundance and richness of these ...

There are three genera - Senecio, Centaurea, and Artemisia - that are especially well known for silvery foliage. Most are low growing species, usually perennials between 1 foot and 4 feet tall. They are generically known as dusty millers, including a most popular species with pointed, finely cut foliage (Senecio viravira), and another with blunt or rounded leaf tips and serrations (Senecio cineraria).. Both sport small yellow or white daisies - dusty millers belong to the daisy family - that are nothing special to look at. Some people remove the flowers as soon as they appear in order to direct the energy of the plant into leaf production alone.. Centaurea cineraria/gymnocarpa has the most interesting flowers among all the dusty millers. They are violet purple and are borne abundantly on and off throughout the year. While reaching 3 feet or taller, the growth habit of this species is rather compact and so it is eminently possible and even advisable to train this plant into a distinctive ...

Advancing our ability to use invasive plants for producing commodities is central to the agricultural industry. Our objective was to evaluate Russian knapweed (Acroptilon repens [L.] DC.) as a winter feed supplement for ruminant livestock. In Experiment 1, we utilized three ruminally cannulated steers in a completely randomized design to compare the ruminal degradation characteristics of alfalfa and Russian knapweed. In the second experiment, Russian knapweed and alfalfa were compared as protein supplements using 48 midgestation, beef cows (530 ± 5 kg) offered ad libitum hard fescue (Festuca brevipila Tracey) straw in an 84-d study. Treatments included an unsupplemented control and alfalfa or Russian knapweed provided on an iso-nitrogenous basis.

One of the antitrypanosomal hits was a dichloromethane (DCM) extract of the cornflower Centaurea salmantica with a growth inhibition of 61% tested at 4.81 µg/mL against T. b. rhodesiense. HPLC-based activity profiling led to the identification of the sesquiterpene lactone (STL) cynaropicrin (CYN), which was the first plant NP to show in vivo efficacy in T. b. rhodesiense infected mice, treated i.p. at 10 mg/kg/b.i.d. for four consecutive days. Despite of more than 10000 known STLs is a better understanding of the structural features, which contribute to activity, expedient. The established structure-activity relationship (SAR) study included 18 natural STLs and demonstrated that antitrypanosomal and cytotoxic effect depended on their a,ß-unsaturated enone moieties. Many bioactivities of STLs have been attributed to a nucleophilic Michael-addition of these functional motifs to biological thiols. Considering that trypanosomes depend on their unique trypanothione-based redox system to deal with ...
The Centaurea leafcutting bee (Megachile apicalis) is an invasive solitary bee and an established member of the cavity-nesting bee community in the western U.S. As fine-scale genetic markers, microsatellite loci used in comparative population genetic analyses may identify factors underlying this biological invasion from contemporary samples of this species. Our objective in this study was to investigate the suitability of cross-species microsatellite primers to amplify microsatellite PCR products in native and invasive populations of M. apicalis. Use of existing microsatellite primers from related species provides a much faster and cheaper alternative to traditional microsatellite isolation methods. We used five of six microsatellite primer sets developed for another megachilid solitary bee, Osmia rufa, to amplify homologous microsatellite loci in M. apicalis. We amplified DNA of bees from native populations in Lesvos (Greece) and Uludag University (Republic of Turkey) by PCR and conducted ...

[Microdontomerus impolitus sp. n. and Liodontomerus centaureae sp. n. are described from cynipid galls on Tragopogon and Centaurea respectively. New host and distributional data are given for M. crassipes Bouček. L. papaveris (Förster), Chalcimerus borceai Steffan & Andriescu and Megastigmus dumicola Bouček, and generic characters of Microdontomerus and Liodontomerus are commented upon., A group of species belonging to the Ectobiinae is described in which the male genitalia show a reversed right-left asymmetry. The aberrant orientation can be explained by the mutation of a developmental gene regulating the right-left asymmetry of the last abdominal sternites. The hypothesis is put forward that similar mutations might also be responsible for the unique arrangement of the phallomere sclerites in the Plectopterinae and Blaberidae. The assumption of a symmetry reversal in the ancestors of these taxa is supported by the study of the muscular connections of the sclerites. As a consequence a new homology

Research conducted under this Reimbursable Agreement directly supports objective 3 of project 5325-22000-026-00D and Objectives 2, 3 and 4 of project 5325-22000-024-00D. Efforts currently are focusing on the use of biological control to aid in the management of Eurasian watermilfoil in western waterways and on the impact of natural enemies on terrestrial plants such as yellow starthistle and French broom. Additionally, this project has provided resources to help assess overall Eurasian watermilfoil growth and development in infested waterways and to assess growth potential of native plants that can compete with weeds and slow the invasion process. Specific experimental studies on Zannichellia palustris (horned pond weed) have focused on natural plant phenology, growth and reproduction in critical waterways and on the seed germination and establishment processes in spring fed rivers. These efforts have led to restoration studies with the aim of augmenting Z. palustris within critical habitats in ...

During my searches for specimens to photograph, I begin to notice subtle things that would normally not be seen. A number of fly and moth larvae live inside the seedheads of flowers such as Knapweed, or Hardheads. This is a good place to hide, since there is a ready supply of food and the larvae are protected from the weather and from most predators or parasites. Notice the word most: I have found carnivorous beetle nymphs inside these seedheads and, of course, the relevant ichneumonids are equipped with long ovipositors that can reach inside the deepest seedheads. I like to find out which larvae are living inside the seedheads, and the best way to find out is to open them. But, of course, I have lots of failures: many seedheads are empty ...

Crude aqueous and methanolic extracts of 63 plant species belonging to 23 families collected from the west of Iran were screened for antifungal activity against three economically important phytopathogenic fungi, Cochliobolus sativus, Fusarium oxysporum and Rhizoctonia solani. Bioassay of extract was conducted by paper disc diffusion method on agar plate cultures with four replications. 21 of the 63 (33%) plant species showed inhibitory activity against at least one of the fungi. 16 (25%), 10 (16%) and 16 (25%) tested plant species inhibited the mycelial growth of R. solani, F. oxysporum and C. sativus, respectively. Centaurea behen, Lavandula sp., roots of Tribulus terrestris were the most active plant species against R. solani, F. oxysporum, and C. sativus, respectively. Extracts of I and T. terrestris exhibited a broad-spectrum of antifungal activity. According to these results, we conclude that the flora in the west of Iran can be regarded as a rich source of plants with antifungal activity. ...
Common chicory, Cichorium intybus, is a somewhat woody, perennial herbaceous plant of the dandelion family Asteraceae, usually with bright blue flowers, rarely white or pink. Many varieties are cultivated for salad leaves, chicons (blanched buds), or roots (var. sativum), which are baked, ground, and used as a coffee substitute and additive. It is also grown as a forage crop for livestock. It lives as a wild plant on roadsides in its native Europe, and is now common in North America, China, and Australia, where it has become widely naturalized. Chicory is also the common name in the United States for curly endive (Cichorium endivia); these two closely related species are often confused. Common chicory is also known as blue daisy, blue dandelion, blue sailors, blue weed, bunk, coffeeweed, cornflower, hendibeh, horseweed, ragged sailors, succory, wild bachelors buttons, and wild endive. (Note: Cornflower is commonly applied to Centaurea cyanus.) Common names for varieties of var. foliosum ...

At the upper part of the drift line, only annual halo-nitrophilous species survive, like Cakile maritima and Polygonum maritimum. Immediately behind this, the sand dune ecosystem begins, with the first line of moving dunes. Here, the sand stabilizers, specialized plants that ancor the sand, form embryonic dunes, like the sand couch grass (Elytrigia juncea), or larger white dunes, like marram grass (Ammophila arenaria), which occurs only at the extended beach of Laganas. Other ammophilous species occuring on Zakynthos dunes are Cyperus capitatus, Echinophora spinosa, the sea lily (Pancratium maritimum) and the sea holly (Eryngium maritimum). Behind the moving dunes, the fixed grey dunes are formed, with small bushes such as Helianthemum nummularium and the thyme (Coridothymus capitatus) at Laganas or with perennial herbs like Verbascum sinuatum and Centaurea seridis subsp. sonchifolia at Marathonisi. At more humid sites, especially at wet dune slacks, there are hydrophilous species such as ...
