Comparisons of 5′ and 3′ boundaries of sequences submitted by different authors. AY766358 was submitted in 2007 by Milstein and Oliveira as “group I intron.” AY573851 was submitted in 2004 by Teasdale, Klein, West, and Mathieson as “group ICI intron.” Remaining sequences were submitted in 2002 by Broom et al. as “putative group IC1 intron.”
