Integrating Horizontal Gene Transfer And Common Descent To Depict Evolution And Contrast It With ‘‘Common Design, Guillermo Paz-y-Mino C., Avelina Espinosa 2010 University of Massachusetts Dartmouth

Integrating Horizontal Gene Transfer And Common Descent To Depict Evolution And Contrast It With ‘‘Common Design, Guillermo Paz-Y-Mino C., Avelina Espinosa

Feinstein College of Arts & Sciences Faculty Publications

Horizontal gene transfer (HGT) and common descent interact in space and time. Because events of HGT co-occur with phylogenetic evolution, it is difficult to depict evolutionary patterns graphically. Tree-like representations of life’s diversification are useful, but they ignore the significance of HGT in evolutionary history, particularly of unicellular organisms, ancestors of multicellular life. Here we integrate the reticulated-tree model, ring of life, symbiogenesis whole-organism model, and eliminative pattern pluralism to represent evolution. Using Entamoeba histolytica alcohol dehydrogenase 2 (EhADH2), a bifunctional enzyme in the glycolytic pathway of amoeba, we illustrate how EhADH2 could be the product of both horizontally ...

Introduction: Protistan Biology, Horizontal Gene Transfer, And Common Descent Uncover Faulty Logic In Intelligent Design, Avelina Espinosa

Feinstein College of Arts & Sciences Faculty Publications

THE International Society of Protistologists (ISOP) organized a pre-meeting workshop entitled ‘‘Horizontal Gene Transfer and Phylogenetic Evolution Debunk Intelligent Design,’’ as part of the 1st North American Section meeting held June 11–13, 2009, at Roger Williams University, Bristol, RI, USA. This workshop focused on the acceptance of Darwinian evolution in the United States and the role of intelligent design (ID) in the ongoing controversy between scientific knowledge and popular belief. Intelligent design, a doctrine born in the 1980s, proposes that a ‘‘Designer’’ is responsible for the complexity in biological systems and that Darwinism cannot explain holistically the origin and ...

Culex quinquefasciatus (the southern house mosquito) is an important mosquito vector of viruses such as West Nile virus and St. Louis encephalitis virus, as well as of nematodes that cause lymphatic filariasis. C. quinquefasciatus is one species within the Culex pipiens species complex and can be found throughout tropical and temperate climates of the world. The ability of C. quinquefasciatus to take blood meals from birds, livestock, and humans contributes to its ability to vector pathogens between species. Here, we describe the genomic sequence of C. quinquefasciatus: Its repertoire of 18,883 protein-coding genes is 22% larger than that of ...

The mosquito Culex quinquefasciatus poses a significant threat to human and veterinary health as a primary vector of West Nile virus (WNV), the filarial worm Wuchereria bancrofti, and an avian malaria parasite. Comparative phylogenomics revealed an expanded canonical C. quinquefasciatus immune gene repertoire compared with those of Aedes aegypti and Anopheles gambiae. Transcriptomic analysis of C. quinquefasciatus genes responsive to WNV, W. bancrofti and non-native bacteria facilitated an unprecedented meta-analysis of 25 vector-pathogen interactions involving arboviruses, filarial worms, bacteria and malaria parasites, revealing common and distinct responses to these pathogen types in three mosquito genera. Our findings provide support for ...


Tritrophic Effects Of Host Plants On An Herbivore-Pathogen Interaction, Aaron J. Gassmann, S. Patricia Stock, Bruce E. Tabashnik, Michael S. Singer 2010 Iowa State University

Tritrophic Effects Of Host Plants On An Herbivore-Pathogen Interaction, Aaron J. Gassmann, S. Patricia Stock, Bruce E. Tabashnik, Michael S. Singer

Entomology Publications

Tritrophic interactions may include directly harmful effects of host plants on herbivores, and directly or indirectly harmful effects of host plants on the natural enemies of herbivores. Tritrophic interactions involving parasitoids and predators have received considerable attention but less is known about how host plants affect entomopathogens. We compared growth and resistance to entomopathogenic nematodes for “woolly bear” caterpillars, Grammia incorrupta(=geneura) (Hy. Edwards) (Lepidoptera: Arctiidae) fed lettuce, Lactuca sativa L. (Asteraceae), versus threadleaf groundsel, Senecio longilobus Benth. (Asteraceae). Both plants are members of the Asteraceae, but only S. longilobus contains pyrrolizidine alkaloids. Caterpillars gained more mass when fed L ...


Proteases As Insecticidal Agents, Robert L. Harrison, Bryony C. Bonning 2010 United States Department of Agriculture

Proteases As Insecticidal Agents, Robert L. Harrison, Bryony C. Bonning

Entomology Publications

Proteases from a variety of sources (viruses, bacteria, fungi, plants, and insects) have toxicity towards insects. Some of these insecticidal proteases evolved as venom components, herbivore resistance factors, or microbial pathogenicity factors, while other proteases play roles in insect development or digestion, but exert an insecticidal effect when over-expressed from genetically engineered plants or microbial pathogens. Many of these proteases are cysteine proteases, although insect-toxic metalloproteases and serine proteases have also been examined. The sites of protease toxic activity range from the insect midgut to the hemocoel (body cavity) to the cuticle. This review discusses these insecticidal proteases along with ...

Video-Tracking And On-Plant Tests Show Cry1ab Resistance Influences Behavior And Survival Of Neonate Ostrinia Nubilalis Following Exposure To Bt Maize, Jarrad R. Prasifka, Richard L. Hellmich, Andre Lb Crespo, Blair D. Siegfried, David W. Onstad

Entomology Publications

To examine how resistance to Bacillus thuringiensis (Bt) toxins influences movement and survival of European corn borer (Ostrinia nubilalis [Hübner]) neonates, the responses of Cry1Ab-resistant , -susceptible, and hybrid (F1) larvae were examined using two different techniques. First, using an automated video-tracking system, aspects of O. nubilalis movement were quantified in the presence of artificial diet incorporating 50% non-Bt or insect-resistant Cry1Ab maize tissue. Second, O. nubilalis dispersal and survival were measured 48–72 h after hatching on a Cry1Ab maize plant surrounded by two non-Bt maize plants. Video tracking indicated the presence of Cry1Ab tissue increased the total distance moved ...

One anticipated benefit of ecosystem restoration is water quality improvement. This study evaluated NO3-N and phosphorus in subsurface waters during prairie establishment following decades of row-crop agriculture. A prairie seeding in late 2003 became established in 2006. Wells and suction cup samplers were monitored for NO3-N and phosphorus. Nitrate-N varied with time and landscape position. Nondetectable NO3-N concentrations became modal along ephemeral drainageways in 2006, when average concentrations in uplands first became <10mg NO3-N L−1. This decline continued and upland groundwater averaged near 2mg NO3-N L−1 after 2007. The longer ...

Of the 70 cases of classical biological control for the protection of nature found in our review, there were fewer projects against insect targets (21) than against invasive plants (49), in part, because many insect biological control projects were carried out against agricultural pests, while nearly all projects against plants targeted invasive plants in natural ecosystems. Of 21 insect projects, 81% (17) provided benefits to protection of biodiversity, while 48% (10) protected products harvested from natural systems, and 5% (1) preserved ecosystem services, with many projects contributing to more than one goal. In contrast, of the 49 projects against invasive ...


Cockroaches, Ryan S. Davis 2010 Utah State University

Cockroaches, Ryan S. Davis

All Current Publications

Cockroaches are one of the most difficult structural pests to eradicate because of their ability to hide, rapid reproduction, and resistance to and avoidance of many commonly used insecticide sprays and baits. Using an integrated pest management (IPM) program can greatly increase the possibility of successful control. There are 4 cockroach species that commonly infest structures in Utah, each with a specific biology; identify invading cockroaches before you develop an IPM plan. Proper identification of any pest will allow you to understand its biology, and use it against itself!

Background: Next generation sequencing is transforming our understanding of transcriptomes. It can determine the expression level of transcripts with a dynamic range of over six orders of magnitude from multiple tissues, developmental stages or conditions. Patterns of gene expression provide insight into functions of genes with unknown annotation.

Results: The RNA Seq-Atlas presented here provides a record of high-resolution gene expression in a set of fourteen diverse tissues. Hierarchical clustering of transcriptional profiles for these tissues suggests three clades with similar profiles: aerial, underground and seed tissues. We also investigate the relationship between gene structure and gene expression and find ...

First Report Of Field Populations Of Two Potential Aphid Pests Of The Bioenergy Crop Miscanthus × Giganteus, Jeffrey Bradshaw, Jarrad R. Prasifka, Kevin L. Steffey, Michael E. Gray

Panhandle Research and Extension Center

Sipha flava (Forbes) (yellow sugarcane aphid) and Rhopalosiphum maidis (Fitch) (corn leaf aphid) (Hemiptera: Homoptera: Aphididae) are common aphids occurring throughout North America on many host plants, most of which are grasses (Blackman & Eastop 2006). Both aphids are pests of several important food crops, e.g., Sorghum bicolor (L.) Moench (sorghum), Saccharum officinarum L. (sugarcane), Triticum spp. (wheat), and Zea mays L. (corn) (Blackman & Eastop 2000). Additionally, both aphids are vectors of potyviruses and R. maidis is a vector of luteoviruses in these crops. Until now, to our knowledge, no natural infestations of these aphids have been reported on the grass genus Miscanthus.

Miscanthus spp. is a common grass throughout the United States, with ornamental varieties of M. sinensis Andersson being the most frequently cultivated species. However, M. × giganteus Greef and Deuter ex Hodkinson and Renvoize (Liliopsida: Poaceae: Andropogonaeae: Saccharinae) is being evaluated in the United States as a cellulosic feedstock crop (Heaton et al. 2008) primarily to meet production targets for advanced biofuels (e.g., cellulosic ethanol; Energy Independence and Security Act of 2007, 42 U.S.C. § 17001). Miscanthus × giganteus is a perennial, sterile hybrid (possibly between M. sinensis and M. sacchiflorus (Maxim.) Hack.) and may exist in nature within a sympatric zone of these 2 species in southeastern Asia (Clifton-Brown et al. 2008).

The Development Of An Efficient Multipurpose Bean Pod Mottle Virus Viral Vector Set For Foreign Gene Expression And Rna Silencing, Chunquan Zhang, Jeffrey Bradshaw, Steven A. Whitham, John H. Hill

Panhandle Research and Extension Center

Plant viral vectors are valuable tools for heterologous gene expression, and because of virus-induced gene silencing (VIGS), they also have important applications as reverse genetics tools for gene function studies. Viral vectors are especially useful for plants such as soybean (Glycine max) that are recalcitrant to transformation. Previously, two generations of bean pod mottle virus (BPMV; genus Comovirus) vectors have been developed for overexpressing and silencing genes in soybean. However, the design of the previous vectors imposes constraints that limit their utility. For example, VIGS target sequences must be expressed as fusion proteins in the same reading frame as the ...

Factors Affecting The Alkaline Cooking Performance Of Selected Corn And Sorghum Hybrids, Weston B. Johnson, Wajira S. Ratnayake, David S. Jackson, Kyung-Min Lee, Timothy J. Herrman, Scott R. Bean, Stephen Mason

Agronomy & Horticulture -- Faculty Publications

Dent com (Zea mays L.) and sorghum (Sorghum hieolor L. Moench) sample sets representative of commonly grown hybrids and diverse physical attributes were analyzed for alkaline cooking performance. The influence of kernel characteristics including hardness, density, starch properties (thermal. pasting, and crystallinity). starch content. protein content. and prolamin content on alkaline cooking performance was also determined. Com nixtamal moisture content was lower for hard, dense kernels with high protein contents; sorghum nixtamal moisture content was lower for kernels with low moisture contents and low starch relative crystallinities. Statistically significant (P < 0.05) regression equations showed that com nixtamal moisture content was influenced by TADD (tangential abrasive dehulling device) index. kernel moisture content. starch content. and protein content; sorghum nixtamal moisture content was influenced by starch relative crystallinity. kernel moisture content, and abrasive hardness index. Pericarp removal was not strongly correlated with kernel characterization tests. Location (environmental) and hybrid (genetic) factors influenced most kernel characteristics and nixtamalization processing variables.
