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.
