Using PFG electrophoresis techniques, the authors have examined the organization of rRNA gene in halobacterium species. The results show that the organization of rRNA genes among closely related halobacteria is quite heterogeneous. This contrasts with the high degree of conservation of rRNA sequence. The possible mechanism of such rRNA gene amplification and its evolutionary implications are discussed.
