Spiroplasma species share common DNA sequences among their viruses, plasmids and genomes.
Journal - Annales de l'Institut Pasteur. Microbiology (FRANCE )
Alkaline-Southern-blot analyses showed that a spiroplasma plasmid, pRA1, obtained from Spiroplasma citri (Maroc-R8A2), contained DNA sequences that were homologous to spiroplasma type 3 viruses (SV3) obtained from S. citri (Maroc-R8A2), S. citri (608) and S. mirum (SMCA). In addition, pRA1 and SV3(608) DNA shared common, but not necessarily related, sequences with extrachromosomal DNA derived from 11 Spiroplasma species or strains. Furthermore, SV3(608) had DNA homology with the chromosome from 6 distinct spiroplasmas but not with chromosomal DNA from eight other Spiroplasma species or strains. The biological function of these common sequences is unknown.
