Incidence of a new sex–ratio–distorting endosymbiotic bacterium among arthropods
The results indicate that, although not as prevalent as Wolbachia, the CLO infects a significant number of arthropod hosts (ca. 7.2%) and Sequencing analysis of the 16S rDNA region of theCLO indicates evidence for horizontal transmission of the ClO strains. Expand
Wolbachia pipientis: microbial manipulator of arthropod reproduction.
The alpha-proteobacterium Wolbachia pipientis is a very common cytoplasmic symbiont of insects, crustaceans, mites, and filarial nematodes that has evolved a large scale of host manipulations: parthenogenesis induction, feminization, and male killing. Expand
A New Huanglongbing Species, “Candidatus Liberibacter psyllaurous,” Found To Infect Tomato and Potato, Is Vectored by the Psyllid Bactericera cockerelli (Sulc)
ABSTRACT A new huanglongbing (HLB) “Candidatus Liberibacter” species is genetically characterized, and the bacterium is designated “Candidatus Liberibacter psyllaurous.” This bacterium infects theExpand
Antibiotics cause parthenogenetic Trichogramma (Hymenoptera/Trichogrammatidae) to revert to sex.
Completely parthenogenetic Trichogramma wasps can be rendered permanently bisexual by treatment with three different antibiotics or high temperatures. The evidence strongly suggests that maternallyExpand
Male–killing Wolbachia in two species of insect
Observations reinforce the notion that Wolbachia may be an important agent driving arthropod evolution, and corroborates previous suggestions that male–killing behaviour is easily evolved by invertebrate symbionts. Expand
The utility of internally transcribed spacer 2 DNA sequences of the nuclear ribosomal gene for distinguishing sibling species of Trichogramma
The usefulness of the internally transcribed spacer 2 (ITS2) of the nuclear ribosomal gene complex is tested for providing taxonomic characters to identify Trichogramma species. The ITS2 sequences ofExpand
A Multigene Phylogenetic Study of Clonal Diversity and Divergence in North American Strains of the Plant Pathogen Xylella fastidiosa
Two well-differentiated clades probably originated more than 15,000 years ago, long before the introduction of the nonnative plants that characterize most infections, and suggest that, historically, X. fastidiosa has been a clonal organism. Expand
Molecular identification of microorganisms associated with parthenogenesis
It is concluded that parthenogenesis bacteria and cytoplasmic incompatibility bacteria form a monophyletic group of microorganisms that 'specialize' in manipulating chromosome behaviour and reproduction of insects. Expand
Host Range of Fusarium Dieback and Its Ambrosia Beetle (Coleoptera: Scolytinae) Vector in Southern California.
The aim of this study was to determine the plant host range of the beetle-fungus complex in two heavily infested botanical gardens in Los Angeles County, and revealed 19 tree species that function as reproductive hosts for PSHB. Expand
