Abstract excerpt
Recombination among bacterial extrachromosomal DNAs (EC-DNAs) plays a major evolutionary role by creating genetic diversity, and provides the potential for rapid adaptation to new environmental conditions. Previously, a 7 kbp EC-DNA, EcOYW1, with a geminivirus-like rolling-circle-replication protein (Rep) gene was isolated and characterized from an original wild-type line (OY-W) of onion yellows (OY) phytoplasma,...
