Abstract excerpt
Group II introns are self-splicing RNAs that are frequently assumed to be the ancestors of spliceosomal introns. They are widely distributed in bacteria and are also found in organelles of plants, fungi, and protists. In this study, we present a broadscale phylogenetic analysis of group II introns using sequence data from both the conserved RNA structure and the intron-encoded reverse transcriptase (RT). Two...
