ORF abbreviations use the nomenclature defined in refs 13, 14 and 24. Predicted ORFs are coloured according to biological category: green, bacteriochloropyll biosynthesis genes; orange, carotenoid biosynthesis genes; red, light-harvesting and reaction centre genes; and blue, cytochrome c2. White boxes indicate non-photosynthetic and hypothetical proteins with no known function. Homologous regions and genes are connected by shaded vertical areas and lines, respectively.
