Figure 1

Examples of conserved intron positions between Streblomastix and other eukaryotes. In each case a section of the gene is shown aligned at the amino acid level, and the position of the intron found in all aligned sequences is indicated above by a triangle with a number indicating the phase (0, 1, or 2). Aligned sequences are from three unikont groups, animals (H. sapiens and P. troglodytes), fungi (S. pombe, U. maydis and A. fumigatus), and slime molds (D. discoideum), from one chromalveolate group, the ciliate (P. tetraurelia), and from three plantae groups, land plants (A. thaliana), green algae (Bigelowiella natans nucleomorph), and red algae (Guillardia thet a nucleomorph).
