Establishing Sodalis species as a laboratory model of endosymbionts
… The difficulties in culturing bacterial endosymbionts is highlighted; the ability, with care, to culture S. glossinidius, and the potential to compare to closely-related, free-living species such as Sodalis praecaptivus is vital as a research model for studying symbiosis and …

Diversity and role of bacterial endosymbionts infecting the cassava whitefly, Bemisia tabaci (Gennadius) in Sub-Saharan Africa
… cassava whiteflies, Bemisia tabaci, and their endosymbionts from Tanzania, Uganda, Malawi and Nigeria were described. Cassava in these countries is infested by five whitefly populations, which were infected with diverse endosymbiotic bacteria with varied prevalence. Wolbachia was the most …

THE ROLE OF MICROBIAL ENDOSYMBIONTS IN SORGHUM HALEPENSE INVASIONS: EVIDENCE OF A NEW INVASION STRATEGY, MICROBIALLY ENHANCED COMPETITIVE ABILITY (MECA)
… however, my work shows that bacterial endosymbionts can regulate these traits in the invasive grass <i>Sorghum halepense</i>. Using culture and molecular approaches, I found the invasive grass harbors several bacterial organisms inside the roots and rhizomes. These bacterial …

Unearthing the mechanisms of the mycorrhizal-bacterial symbiosis in plant roots using a metatranscriptomic approach
… and symbiotic species. Recently several obligate endosymbionts of the arbuscular mycorrhizal fungi have been identified, and these bacteria have been shown to modulate both the metabolism and morphology of the fungal symbionts. However, molecular and functional characterization of these bacterial …

Genotypic and endosymbiont-mediated variation in parasitoid susceptibility and other fitness traits of the potato aphid, <em>Macrosiphum euphorbiae</em>
… decades several additional ‘secondary’ bacterial endosymbionts have been detected across different aphid species, although not across all aphid populations. Recent research has revealed that secondary bacterial endosymbionts can affect several aspects of the morphology and ecology of their aphid …

The Dynamics of Natural Enemy Resistance in Aphid Populations
Many aphids harbour facultative bacterial endosymbionts that can influence aphid fitness. In Acyrthosiphon pisum (the pea aphid), the endosymbiont <i>Hamiltonella defensa</i> confers resistance to parasitism by parasitoid wasps due to the presence of the APSE bacteriophage in the …

The nutritional role of endosymbiotic bacteria in animal-bacteria symbioses : Solemya velum, a case study
… those of bivalve controls that do not harbor endosymbionts. The δ34S values of S. velum were very negative and suggest the use of biogenically produced H2S as a S source. The δ13C and δ15N isotope ratios of S. velum suggest that the endosymbiotic bacteria may provide almost 100% of the hosts C …

Integrative approach to discovering species diversity within the Mediterranean group of the Bemisia tabaci complex
… verification, (iii) detection of bacterial endosymbionts and (iv) bioassays to compare their host-plant ranges and performances on 13 plants. Our mitogenome phylogeny showed close relationships among Q1 and Q2 populations, while ASL was placed outside the Q1/Q2 cluster with 100% bootstrap …

Detection and Prevalence of <em>Wolbachia</em> within the Tick <em>Ambyomma americanum</em> and Fleas (Siphonaptera) in Southeast Georgia
<p><em>Wolbachia</em> spp. are intracellular endosymbionts that have been reported from many arthropods and nematodes. However, there is little known of Wolbachia from either ticks or fleas. This is the first report of <em>Wolbachia</em> within the lone star tick, <em>Amblyomma</em> …

Integrating Above and Belowground Components of Biodiversity across Spatial Scales: The Role of Host Plants in the Distribution of Arbuscular Mycorrhizal Fungi
… (AM) fungi are a group of obligate plant root endosymbionts, which form associations with an estimated two thirds of terrestrial plant species. Their extra-radical mycelium extends throughout the soil and absorbs nutrients that are transferred to their host plant in exchange for a purely …

Haemophilus influenzae as a chassis for directed endosymbiosis
… make it attractive for engineering bacterial endosymbionts. First, H. influenzae strains lacking the restriction endonuclease genes HindIIR and HindIIIR were shown to transform more efficiently by electroporation than wild-type. A pSU20-derived plasmid series was then developed to provide …

Lipid biomarkers of coral stress : calibration and exploration
… symbiosis between corals and their algal endosymbionts (zooxanthellae) is easily disrupted by thermal stress, leading to bleaching and eventual mortality. The use of lipid ratios as biomarkers of environmental conditions is well established. Coral biomass contains abundant lipids, and the …

Sisters' curse: sexually antagonistic selection constrains the spread of a rare mitochondrial haplogroup
… in the cytoplasm, including DNA in cellular endosymbionts and mitochondria. Because males are an evolutionary dead end for mitochondria, mutations in the mitochondrial genome that are harmful or beneficial to males but not to females cannot respond directly to selection. Few studies have …

Predator-prey behavioural interactions on plants, with special emphasis on aphid dropping defence and ladybird search strategies
… factors, such as genotype and the presence of endosymbionts. The nature and proximity of the predatory threat also affect dropping. Further, the consequences of dropping depend on many factors, including where on a plant predator-prey encounters occur; this in turn will be influenced by …

Metabolomics as a tool in the identification and production of new marine-derived antibiotics from sponges and endosymbiotic bacteria
… drugs. Marine sponges and their endosymbionts have proven to be abundant sources of bioactive compounds. HR-LCFTMS and NMR were used in the identification of compounds isolated from a marine bacterium and its host sponge, as well as in the dereplication and metabolic profiling of …
