    Notes:
    . We have determined the complete nucleotide sequence of the coding region of the small subunit rRNA gene expressed by bloodstream stages of the apicomplexan Plasmodium berghei. It is 2059 nucleotides long. Elements contributing to its relatively large size are all concentrated in regions known to be variable in length among eukaryotes. In a phylogenetic tree constructed from pairwise comparisons of eukaryotic small subunit rRNA sequences, the apicomplexan line branches at a rather early point in eukaryotic evolution before any multicellular kingdoms had yet appeared.

    Notes:
    . We have determined the complete nucleotide sequence of the coding region of the small subunit rRNA gene of the hypotrichous ciliate Euplotes aediculatus. It is 1882 nucleotides long and contains several inserts not present in the small subunit rRNA genes of the hypotrichs Oxytricha nova and Stylonychia pustulata. A comparison of the sequences suggests that E. aediculatus is much less closely related to these other two hypotrichs than they are to each other. Although the gene sequence of E. aediculatus is drifting more rapidly than those of these other two species, its faster evolutionary clock is not enough to account for the degree of difference between them.
