Figure 1
Schematic representation of the mt genome of D. pteronyssinus. Except for atp8 (= 8) and nad4 (= 4L) protein coding and ribosomal genes are presented as outlined in the abbreviations section. tRNA genes are abbreviated using the one-letter amino acid code, with L1 = CUN; L2 = UUR; S1 = AGN; S2 = UCN. RNAs on the N-strand are underlined. Numbers at gene junctions indicate the length of small non-coding regions where negative numbers indicate overlap between genes. A-,T-,G- and C-content of the mt genome is represented using a red, blue, green and purple colour graded circle, respectively. Black curved lines on the outside of these circles represent mt genome coverage by Dermatophagoides ESTs (see additional file 5 for sequences of Dermatophagoides ESTs covering the mt genome of D. pteronyssinus).
