Maurino VG, Peterhansel C. Genomics anclent evolution of heritable bacterial symbionts. Plant peptides govern terminal differentiation ofbacteria in symbiosis. The symbionts may live within the host’s cells intracellular or outside cells extracellular in multicellular hosts. Ancient invasions by eubacteria through symbiosis more than a billion years ago initiated these processes.

Immunology Today 12 3: Comparative genomic studies suggest that the cyanobacterial endosymbionts of the amoebaPaulinella chromatophora possess an import apparatus for nuclearencodedproteins.


Endosymbionts may live inside host cells or outside cells in multicellular hosts. From This Paper Figures, tables, and topics from this paper. Abstract Endosymbionts are smaller symbiotic partners living inside a host organism, establishing endosymbiosis. De novo pyrimidine nucleotide synthesis mainly occurs outside of plastids, but anckent previously undiscoverednucleobase importer provides substrates for the essentialsalvage pathway in Arabidopsis.
