Expansin 3′ UTRs contain a combination of conserved sequences, which are also present in the 3′ UTR of the localized Zinnia elegans Exp1 mRNA. (A) Sequence LOGO plots are generated by MEME; information content of a position is represented by stack height, which is multiplied by letter frequency at that position to give letter height. Each Expansin mRNA has one upstream variable region and one downstream RCCCGC-core motif. The entire MEME-derived alignment is given for AT2G03090.1 group's variable region. (B) Alignment of the Zinnia elegans ExpansinA1 mRNA (Ze)—gi|7025490|gb|AF230331.1—which is targeted to specific subcellular sites, with its A. thaliana ortholog (At)—AT2G40610.1. mORF stop codons are in red, and conserved elements are in blue. Asterisks indicate that the column letters are identical. Note: (U)racils are shown as (T)hymines.
