Spiroplasma turonicum was isolated from a Haematopota sp. fly in France. We report the nucleotide sequence of the circular chromosome of strain Tab4c(T). The genome information will facilitate evolutionary studies of spiroplasmas, including symbionts of insects and ticks and pathogens of plants, insects, crustaceans, and humans.

Spiroplasma kunkelii causes corn stunt disease of Zea mays L. in the Americas. Here, we report the nucleotide sequence of the 1,463,926-bp circular chromosome and four plasmids of strain CR2-3x. This information will facilitate studies of Spiroplasma pathogenicity and evolutionary adaptations to transkingdom parasitism in plants and insect vectors.

Horizontal gene transfer (HGT) is an important mechanism that contributed to biological diversity, particularly in bacteria. Through acquisition of novel genes, the recipient cell may change its ecological preference and the process could promote speciation. In this study, we determined the complete genome sequence of two Spiroplasma species for comparative analyses and inferred the putative gene gains and losses. Although most Spiroplasma species are symbionts of terrestrial insects, Spiroplasma eriocheiris has evolved to be a lethal pathogen of freshwater crustaceans. We found that approximately 7% of the genes in this genome may have originated from HGT and these genes expanded …

Background: The genus Spiroplasma contains a group of helical, motile, and wall-less bacteria in the class
Mollicutes. Similar to other members of this class, such as the animal-pathogenic Mycoplasma and the
plant-pathogenic ‘Candidatus Phytoplasma’, all characterized Spiroplasma species were found to be associated with
eukaryotic hosts. While most of the Spiroplasma species appeared to be harmless commensals of insects, a small
number of species have evolved pathogenicity toward various arthropods and plants. In this study, we isolated a
novel strain of honeybee-associated S. melliferum and investigated its genetic composition and evolutionary history
by whole-genome shotgun sequencing and comparative analysis with …
