Circular gene maps of the complete mitochondrial genome for Bursaphelenchus xylophilus (A) and Pratylenchus vulnus (B). All genes are encoded in the same direction and 22 tRNA genes are designated by a single-letter abbreviation. The two leucine and two serine tRNA genes are labeled, according to their anticodon sequence, as L1 (trnL-uag), L2 (trnL-uaa), S1 (trnS-ucu), and S2 (trnS-uga), respectively.
