Figure 1

Average base abundance at each position of the 45-nucleotide polyadenylation [poly(A)] site regions in protists. Sequence logo (seqlogo) position from left to right: 5′ to 3′ of the DNA sequences. Position 31 in the seqlogo graphs is the poly(A) site—the poly(A) tail starting position. Note that i) the base abundance pattern was very different in each of the protist species, ii) the poly(A) site was mainly an A in Trypanosoma cruzi, Phytophthora infestans, and Chlamydomonas reinhardtii but was not an A in Blastocystis hominis, and iii) the signature region could be upstream of (C. reinhardtii), at (T. cruzi), or downstream of (B. hominis) the poly(A) site.
