摘要

Bodyl's hypothesis posits replacement of an incumbent plastid with a different plastid acquired through engulfment and retention of a photosynthetic eukaryote, a process known as secondary endosymbiosis. He suggests that both the nucleusencoded genes and the targeting machinery of the incumbent plastid could service the newly acquired plastid, thereby obviating the need for further gene transfer and reinventing complicated targeting of nucleus-encoded proteins into a plastid surrounded by multiple membranes. Such streamlined plastid evolution is argued to have enabled the multiple establishment of secondary endosymbionts in diverse lineages. Dinoflagellates are noted as a group in which 'replacement' appears to have resulted in endosymbionts of various colours and evolutionary affinities replacing the 'ancestral' peridinin plastid (bounded by three membranes).
