Nai et al. BMC Genomics 2010, 11:116 http://www.biomedcentral.com/1471-2164/11/116 Page 5 of 14 Figure 2 Gene parity plots comparing ORF content and order of LyxyMNPV with (a) LdMNPV, (b) SeMNPV, (c) AcMNPV, (d) OpMNPV, (e) MaviMNPV and (f) CpGV. ORFs present in only one of the compared genomes appear on the axis corresponding to the virus in which they are present.
