Gene content and arrangement of cryptophyte mitochondrial genomes. Twelve synthetic blocks (A–L) and two rRNAs are described relative to a phylogenetic tree of cryptophytes. Putative gene rearrangements are indicated with numbers (1–23). Tandem repeat regions are marked with red triangles. The most conserved syntenic blocks among cryptophytes are marked; * = 100%, and † = broken by one gene. The hairpin structures with palindromic sequences are marked blue (hairpin symbol). The tRNAs are coded with single letters and tRNAs with palindromic sequences are highlighted red
