摘要：

The evolution of the plastid from a photosynthetic bacterial endosymbiont involved a dramatic reduction in the complexity of the plastid genome, with many genes either discarded or transferred to the nucleus of the eukaryotic host. However, this evolutionary process has not gone to completion and a subset of genes remains in all plastids examined to date. The various hypotheses put forward to explain the retention of the plastid genome have tended to focus on the need for photosynthetic organisms to retain a genetic system in the chloroplast, and they fail to explain why heterotrophic plants and algae, and the apicomplexan parasites all retain a genome in their non-photosynthetic plastids. Here we consider two additional explanations: the 'essential tRNAs' hypothesis and the 'transfer-window' hypothesis.
