—Distribution of 11 patchily distributed genes in the major photosynthetic eukaryotic groups. These genes show outright gene losses, pseudogenes, and intron insertions. The cladogram was built using a concatenated data set of 88 plastid genes (fig. 3 and supplementary table S1, Supplementary Material online). The 11 target genes are color-coded: purple = three LIPOR genes, yellow = dnaX gene, and dark blue = dnaK, groEL, ftsH, minD/E, hlpA, and dnaB genes. The open white circles indicate gene absence in plastid genomes.
