Fig. 1.

Sequence structure of 19 haplotypes identified in nad7-1 of P. tabuliformis. (A) The two conserved blocks are indicated by a black rectangle; seven motifs are indicated by pentagons with colors corresponding to those used in (B); the highly variable motif Rp is indicated by gray pentagons with the length labeled. The superscript latter "a" and "b" indicated two different Rp motifs with same length; and the TAG7 microhomology is indicated by a blue open triangle. Three insertions specific to a subset of motifs are indicated by yellow, light blue, and black arrows. A large sequence block (DUP) duplicated in H11–19 is outlined in red. (B) Alignment of the seven motifs.
