The Draft Genome and Transcriptome of the Atlantic Horseshoe Crab, Limulus polyphemus

Figure 1

Gene map of the Limulus polyphemus mitochondrial genome. Arrows indicate strand direction with the inner circle representing genes on the light strand while the outer circle represents genes on the heavy strand. ND1–6 represents nicotinamide adenine dinucleotide dehydrogenase (NADH) subunit variants. tRNA (“amino acid”) represents transfer RNA variants. COX1–3 represents the cytochrome c oxidase subunits. CYTB represents cytochrome b oxidase. ATP6 and ATP8 represent adenosine triphosphate variants 6 and 8. Rrn12 and rrn16 represent ribosomal subunits 12 and 16. Innermost dark grey circle represents distribution of GC content.
