英文摘要	The forfeiting of photosynthetic capabilities has occurred independently many times throughout eukaryotic evolution. But almost all non-photosynthetic plants and algae still retain a colorless plastid and an associated genome, which performs fundamental processes apart from photosynthesis. Unfortunately, little is known about the forces leading to photosynthetic loss; this is largely because there is a lack of data from transitional species. Here, we compare the plastid genomes of two "transitional" green algae: the photosynthetic, mixotrophic Auxenochlorella protothecoides and the non-photosynthetic, obligate heterotroph Prototheca wickerhamii. Remarkably, the plastid genome of A. protothecoides is only slightly larger than that of P. wickerhamii, making it among the smallest plastid genomes yet observed from photosynthetic green algae. Even more surprising, both algae have almost identical plastid genomic architectures and gene compositions (with the exception of genes involved in photosynthesis), implying that they are closely related. This close relationship was further supported by phylogenetic and substitution rate analyses, which suggest that the lineages giving rise to A. protothecoides and P. wickerhamii diverged from one another around six million years ago.
