Phylogenetic relationships among group II intron ORFs.

Nucleic acids research - 1 Mar 2001

Zimmerly S, Hausner G, Wu Xc

Abstract excerpt

Group II introns are widely believed to have been ancestors of spliceosomal introns, yet little is known about their own evolutionary history. In order to address the evolution of mobile group II introns, we have compiled 71 open reading frames (ORFs) related to group II intron reverse transcriptases and subjected their derived amino acid sequences to phylogenetic analysis. The phylogenetic tree was rooted with...
