Are Annulate Lamellae in the Drosophila Embryo the Result of Overproduction of Nuclear Pore Components?
(Rockefeller University Press, 1984-02)Annulate lamellae are cytoplasmic organelles composed of stacked sheets of membrane containing pores that are structurally indistinguishable from nuclear pores. The functions of annulate lamellae are not well understood ... -
Assessing changes to ecosystem structure and function following invasion by Spartina alterniflora and Phragmites australis: a meta-analysis [Supplemental Files]
(Biological Invasions, 2021)Biological invasions resulting from anthropogenic activities are one of the greatest threats to maintaining ecosystem functioning and native biodiversity. Invasions are especially problematic when the invading species ... -
Association of DRG1 and DRG2 with Ribosomes from Pea, Arabidopsis and Yeast
(University of Chicago Press, 2009)DRGs are highly conserved GTP binding proteins.All eukaryotes examined contain DRG1 and DRG2 orthologs. The first experimental evidence for GTP binding by a plant DRG1 protein and by DRG2 from any organism is presented. ... -
Behavior and survival of the filth fly parasitoids Spalangia endius and Urolepis rufipes (Hymenoptera: Pteromalidae) in response to three granular house fly baits and components.
(Oxford University Press, 2016)Behaviors and mortality of two filth fly parasitoid wasps, Spalangia endius Walker and Urolepis rufipes Ashmead, were tested in response to granular fly baits containing one of three active ingredients (AI): Golden Malrin ... -
Benefit of polyandry in a monandrous species when females mate with already mated males
(Springer, 2018)Female mating frequency varies among animal taxa. A benefit to females of remating has usually been found, but almost all tests have been with polyandrous species. A species being monandrous does not guarantee that mating ... -
The Cellulose Synthase Superfamily in Fully Sequenced Plants and Algae
(BioMed Central, 2009-07)Background: The cellulose synthase superfamily has been classified into nine cellulose synthaselike (Csl) families and one cellulose synthase (CesA) family. The Csl families have been proposed to be involved in the ... -
Characterization of the Aspergillus parasiticus delta12-desaturase Gene: A Role for Lipid Metabolism in the Aspergillus/plant Interaction
(Society for General Microbiology, 2004-09)In the mycotoxigenic oilseed pathogens Aspergillus flavus and Aspergillus parasiticus and the model filamentous fungus Aspergillus nidulans, unsaturated fatty acids and their derivatives act as important developmental ... -
Characterization of the putative polysaccharide synthase CpsA and its effects on the virulence of the human pathogen Aspergillus fumigatus
(PLoS One, 2019-04-26)The fungus Aspergillus fumigatus is a ubiquitous opportunistic human pathogen capable of causing a life-threatening disease called invasive aspergillosis, or IA, with an associated 40–90% mortality rate in immunocompromised ... -
Characterization of the recD gene of Neisseria gonorrhoeae MS11 and the Effect of recD Inactivation on Pilin Variation and DNA Transformation
(Society for General Microbiology, 1999-02)Pilin antigenic variation in Neisseria gonorrhoeae may result following intrachromosomal recombination between homologous pi/ genes. Despite extensive study, recA is the only previously characterized gene known to ... -
The Chloroplast Genome of Anomochloa Marantoidea (Anomochlooideae; Poaceae) Comprises a Mixture of Grass-like and Unique Features
(Botanical Society of America, 2010)Features in the complete plastome of Anomochloa marantoidea (Poaceae) were investigated. This species is one of four of Anomochlooideae, the crown node of which diverged before those of any other grass subfamily. The ... -
Compatibility of the parasitoid Spalangia endius (Hymenoptera: Pteromalidae) and insecticides against Musca domestica (Diptera: Muscidae) as evaluated by a new index.
(Oxford University Press, 2015)Various insecticides for the control of the house fly Musca domestica L. were tested for compatibility with a biological control agent, the pupal parasitoid Spalangia endius Walker. Bioassays used the mode in which each ... -
Complete chloroplast genome of Oncidium Gower Ramsey and evaluation of molecular markers for identification and breeding in Oncidiinae
(BioMed Central, 2010)Background: Oncidium spp. produce commercially important orchid cut flowers. However, they are amenable to intergeneric and inter-specific crossing making phylogenetic identification very difficult. Molecular markers ... -
Complex Transitions Between C3 and C4 Photosynthesis During the Evolution of Paniceae: A Phylogenetic Case Study Emphasizing the Position of Steinchisma Hians (Poaceae), A C3-C4 Intermediate
(University of Chicago Press, 2003)A two-tiered, nested molecular phylogenetic study of panicoid grasses to explore character state transitions between the C3 and C4 adaptive syndromes is presented. A broad survey of 92 panicoid species was sampled for ... -
Coordinating Environmental Genomics and Geochemistry Reveals Metabolic Transitions in a Hot Spring Ecosystem
(Public Library of Science, 2012-06-04)We have constructed a conceptual model of biogeochemical cycles and metabolic and microbial community shifts within a hot spring ecosystem via coordinated analysis of the ‘‘Bison Pool’’ (BP) Environmental Genome and a ... -
Courtship Behavior and Detection of Female Receptivity in the Parasitoid Wasp Urolepis rufipes
(Oxford Unifersity Press, 2013-04-09)Once a Urolepis rufipes male mounted, the female beat her antennae against his mouth and clypeus. Immediately after he swept his antennae rapidly downward and extruded his mouthparts, her abdomen rose as she opened her ... -
Cross-Linking Patterns in Salt-Extractable Extensin from Carrot Cell Walls
(American Society of Plant Biologists, 1986)Extensins are hydroxyproline-rich glycoproteins (HRGPs) found in the primary cell walls of dicots. Extensin monomers are secreted into the wall and covalently bound to each other, presumably by isodityrosine (IDT) ... -
Decaying organic matter did not remove sublethal effect of imidacloprid on mating in Spalangia endius (Hymenoptera: Pteromalidae), a parasitoid of filth flies
(Oxford University Press, 2019)Both the parasitoid wasp Spalangia endius Walker and the insecticide imidacloprid are used to control house flies. A recent study found that negative sublethal effects of imidacloprid on killing flies and on offspring ... -
Dissemination of imidacloprid through dairy cattle manure and its effect on the biological control agent, Spalangia endius (Hymenoptera: Pteromalidae), and a filth fly host, Musca domestica (Diptera: Muscidae)
(2019)Filth flies, including house flies, Musca domestica L. (Diptera: Muscidae), develop in animal manure. Adult house flies often are controlled with pesticides such as imidacloprid. How imidacloprid disseminates and persists ... -
