Alignment of the control region (L-strand) of Palea steindachneri and Pelodiscus axenaria. Dots indicate nucleotides identical between the two soft-shelled turtles; dashes indicate indels. The mammalian ETAS1-like sequence at nt 359–401 is colored in purple. Sequences with similarity to conserved blocks B, C, D, E, and F are colored in green. Sequences with similarity to conserved blocks 1, 2, and 3 are colored in orange.
