Molecular Phylogeny of the SELMA Translocation Machinery Recounts the Evolution of Complex Photosynthetic Eukaryotes.

ABSTRACT: Photosynthetic eukaryotes and their relatives are the result of an intricate evolutionary history involving a series of plastid acquisitions through endosymbiosis, multiple reversions to heterotrophy, and sometimes total plastid losses. Among these events, one of the most debated is the emergence and diversification of the CASH lineages (Cryptophyta, Alveolata, Stramenopiles, and Haptophyta). Although they all include species bearing a complex plastid that derived from the endosymbiosis of a red alga, their phylogenetic relationships remain controversial, and the timing and number of plastid acquisitions are still undetermined. The inner metabolism of all plastids is mostly supported by nuclear-encoded proteins, and consequently, mechanisms allowing the relocation of those proteins have ev
