This study describes the organization of the repetitive pattern in the mtDNA control region of Tomistoma schlegelii. Using newly designed primers, we detected length variations of approximately 50-100 bp among individuals, and only one individual showed a heteroplasmic band. Sequencing the region after CSB III revealed two main patterns: a repeat motif and a variable number tandem repeat (VNTR) pattern. The VNTR region, with a core unit of 104 bp, consisting of four motifs and a short AT chain, is implicated in the length variation seen among individuals of Tomistoma. A conserved motif seen in a family unit indicated that the repeat pattern was stably inherited from the maternal parent to all offspring. A combination of VNTR patterns specific to different crocodilians was seen in Tomistoma, and the overall secondary structure was shown to be similar to that in Crocodylus and Gavialis.
