Abstract
Intracellular bacterial symbionts are known from various insect groups, particularly from those feeding on unbalanced diets, where the bacteria provide essential nutrients to the host. In the case of reed beetles (Coleoptera: Chrysomelidae, Donaciinae), however, the endosymbionts appear to be associated with specialized “glands” that secrete a material used for the beetles’ unusual water-tight cocoon. These glands were discovered over a century ago, but the bacteria they contain have yet to be c

Abstract
ABSTRACT The characterization of transcriptional start sites of 14 genes encoded by the extremely AT-rich genome of “ Candidatus Blochmannia floridanus” revealed a high degree of conservation with the RpoD promoter consensus sequence of the free-living relative Escherichia coli . Moreover, in agreement with the presence of the alternative heat shock sigma factor RpoH in “ Ca . Blochmannia,” typical Rpo

Comparative Genome Analysis of “ Candidatus Phytoplasma australiense” (Subgroup tuf -Australia I; rp -A) and “ Ca . Phytoplasma asteris” Strains OY-M and AY-WB

Abstract
ABSTRACT The chromosome sequence of “ Candidatus Phytoplasma australiense” (subgroup tuf -Australia I; rp -A), associated with dieback in papaya, Australian grapevine yellows in grapevine, and several other important plant diseases, was determined. The circular chromosome is represented by 879,324 nucleotides, a GC content of 27%, and 839 protein-coding genes. Five hundred two of these protein-coding g

Abstract
To characterize potentially important surface-exposed proteins of the phytoplasma causing chrysanthemum yellows (CY), new primers were designed based on the conserved regions of 3 membrane protein genes of the completely sequenced onion yellows and aster yellows witches’ broom phytoplasmas and were used to amplify CY DNA. The CY genes secY, amp, and artI, encoding the protein translocase subunit SecY, the antigenic membrane protein Amp and the arginine transporter ArtI, respectively, were clone
