Ectopic transposition of a group II intron in natural bacterial populations.

Molecular microbiology - 1 Aug 2001

Muñoz E, Villadas P J, Toro N

Abstract excerpt

Self-splicing group II introns are thought to be the evolutionary progenitors of eukaryotic spliceosomal introns. The invasion of novel (ectopic) sites by group II introns is considered to be a key mechanism by which spliceosomal introns may have become widely dispersed. However, the dynamics of these events in populations are unknown. In bacteria, only two group II introns have been shown to splice and to be...
