  • Title: The puzzle of plastid evolution.
    Author: Archibald JM.
    Journal: Curr Biol; 2009 Jan 27; 19(2):R81-8. PubMed ID: 19174147.
    Abstract:
    A comprehensive understanding of the origin and spread of plastids remains an important yet elusive goal in the field of eukaryotic evolution. Combined with the discovery of new photosynthetic and non-photosynthetic protist lineages, the results of recent taxonomically broad phylogenomic studies suggest that a re-shuffling of higher-level eukaryote systematics is in order. Consequently, new models of plastid evolution involving ancient secondary and tertiary endosymbioses are needed to explain the full spectrum of photosynthetic eukaryotes.
