Figure 7From: The complete mitochondrial genomes of two rice planthoppers, Nilaparvata lugens and Laodelphax striatellus: conserved genome rearrangement in Delphacidae and discovery of new characteristics of atp8 and tRNA genesHaplotype network based on a fragment of Laodelphax striatellus mitochondrial sequence (642 bp) composing of nad5 (482 bp), trnH (62 bp), 2 intergenic nucleotides and nad4 genes (96 bp). Frequency of each haplotype is proportional to circle area and indicated by the numbers. The numbers on the line between circles represents the positions of each mutational site in the sequence (see more variable nucleotide site information in Additional file 8: Table S5).Back to article page
