Figure 1

Structure of the plastid genomes of P. stagnora and P. cutis. (a,b) Gene maps of the plastid genomes of P. stagnora and P. cutis, respectively. Genes are shown in different coloured boxes according to their putative functions. Genes on the outside of the maps are transcribed in the clockwise direction, and inner genes are transcribed in the counterclockwise direction. (c) Comparison of the gene order of the plastid genomes of C. variabilis, A. protothecoides, P. wickerhamii, P. cutis, P. stagnora, and Helicosporidium sp. Homologous genes are connected by straight lines as shown in the figure. Most of the photosynthesis-related genes (green) are absent in the non-photosynthetic lineages.
