Fig. 6.—

Gene content of highly reduced plastid genomes of seven nonphotosynthetic plants. The gene set shown here excludes gene categories that are missing in most of these extremely reduced plastomes. Black boxes indicate a present gene, white boxes indicate absent gene, and gray boxes indicate a pseudogene. A more comprehensive version of this figure including the full plastome gene set and including the available complete plastomes of hemiparasitic or nonphotosynthetic plants, as well as close photosynthetic relatives, is shown in supplementary figure S4, Supplementary Material online.
