Figure 2 From: The complete plastid genome sequence of the parasitic green alga Helicosporidium sp. is highly reduced and structured GC skew diagram for the Helicosporidium plastid genome. The sum of [G-C]/[G+C] calculated in 37 base, non-overlapping adjacent windows is shown superimposed on a linearized scale map of the genome, starting between the LSU and rpoC2 genes. The global minimum of this plot corresponds to the proposed origin of replication.Back to article page
