TLDR
Wolbachia biology is reviewed, including their phylogeny and distribution, mechanisms of action, population biology and evolution, and biological control implications.Abstract:
▪ Abstract Wolbachia are a common and widespread group of bacteria found in reproductive tissues of arthropods. These bacteria are transmitted through the cytoplasm of eggs and have evolved various mechanisms for manipulating reproduction of their hosts, including induction of reproductive incompatibility, pathenogenesis, and feminization. Wolbachia are also transmitted horizontally between arthropod species. Significant recent advances have been made in the study of these interesting microorganisms. In this paper, Wolbachia biology is reviewed, including their phylogeny and distribution, mechanisms of action, population biology and evolution, and biological control implications. Potential directions for future research are also discussed.read more

Wolbachia: master manipulators of invertebrate biology.
TL;DR: The basic biology of Wolbachia is reviewed, with emphasis on recent advances in the authors' understanding of these fascinating endosymbionts, which are found in arthropods and nematodes.

TL;DR: The Drosophila melanogaster Genetic Reference Panel is described, a community resource for analysis of population genomics and quantitative traits, which reveals reduced polymorphism in centromeric autosomal regions and the X chromosomes, evidence for positive and negative selection, and rapid evolution of the X chromosome.

Wolbachia pipientis: microbial manipulator of arthropod reproduction.
TL;DR: 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.

Phylogeny and PCR–based classification of Wolbachia strains using wsp gene sequences
TL;DR: A method based on the use of group–specificwsp PCR primers which will allow Wolbachia isolates to be typed without the need to clone and sequence individualWolbachia genes is presented, which should facilitate future studies investigating the distribution and biology of these bacteria.

TL;DR: It is shown that some of these inserted Wolbachia genes are transcribed within eukaryotic cells lacking endosymbionts, potentially providing a mechanism for acquisition of new genes and functions.

16S ribosomal DNA amplification for phylogenetic study.
TL;DR: A set of oligonucleotide primers capable of initiating enzymatic amplification (polymerase chain reaction) on a phylogenetically and taxonomically wide range of bacteria is described in this paper.

How close is close: 16S rRNA sequence identity may not be sufficient to guarantee species identity.
TL;DR: Although 16S rRNA sequences can be used routinely to distinguish and establish relationships between genera and well-resolved species, very recently diverged species may not be recognizable.

16S rRNA phylogenetic analysis of the bacterial endosymbionts associated with cytoplasmic incompatibility in insects

TL;DR: Initial screening of insects indicates that cytoplasmic incompatibility may be a more general phenomenon in insects than is currently recognized and Lack of congruence between the phylogeny of the symbionts and their insect hosts suggest that horizontal transfer of symbiont between insect species may occur.

Evolution and Phylogeny of Wolbachia: Reproductive Parasites of Arthropods
TL;DR: A fine-scale phylogenetic analysis was done using DNA sequences from ftsZ, a rapidly evolving bacterial cell-cycle gene, finding that some insects harbour infections with more than one Wolbachia strain, even within individual insects.
