Finding the two plasmids existing in high copy numbers in phytoplasma cells

Presence and characteristic of phytoplasma plasmid are not known too much. Two plasmids associated with two strains of „Candidatus phytoplasma asteris“ have been obtained from two plant species. Both the plasmids were sequenced and six, or five open reading frames were found, respectively, each having nucleotide compossition very similar to phytoplasmas. Frutheremore, a segment of one of plasmids was almost identical to part of phytoplasma genome suggesting strongly, that such a plasmids are made somehow from phytoplasma genome.
