Cross-Species Conservation of 5′ UTR Sequences in Polγ1 and Polγ2.

Multiple sequence alignments of the region upstream to ATG in Polγ1 and Polγ2 from Arabidopsis, O. sativa, N. tabacum, and S. bicolor were performed using the Mcoffee option of the T-Coffee program (http://www.igs.cnrs-mrs.fr/Tcoffee/tcoffee_cgi/index.cgi; Notredame et al., 2000). Blue boxes indicate annotated ATG initiator codons, green boxes indicate CTG initiator sites, and black boxes indicate upstream ATA or ACG putative initiator sites. Within the color spectrum displayed, red regions are in perfect agreement across all methods used within the analysis program, while blue regions have poor agreement, with yellow and green intermediate in alignment score.
