Genomics and chloroplast evolution: what did cyanobacteria do for plants?

Genome Biol. 2003;4(3):209. doi: 10.1186/gb-2003-4-3-209. Epub 2003 Mar 3.


The complete genome sequences of cyanobacteria and of the higher plant Arabidopsis thaliana leave no doubt that the plant chloroplast originated, through endosymbiosis, from a cyanobacterium. But the genomic legacy of cyanobacterial ancestry extends far beyond the chloroplast itself, and persists in organisms that have lost chloroplasts completely.
