The first organism to have its entire genome sequence published was the RNA bacteriophage MS2 (in 1976); the first genome sequence from a DNA bacteriophage (Φ174) was published in 1977. Later that year, Sanger and colleagues published an article detailing the chain-termination sequencing technique, often called the Sanger sequencing method. For more than 20 years, the Sanger sequencing method was the only sequencing method available. The first bacterial genome sequenced by this method, Haemophil…

Figure 2. Full genome alignment of 13 Listeria chromosomes and L. innocua plasmid pLI100 presented as originally published by BMC Central in den Bakker et al. (2010). The outermost circle indicates the source of each gene in the pan-genome. Internal circles indicate gene presence (solid color) or absence (unfilled) of each gene in each of the 13 strains examined. Circles from outer to inner are in the same order as strains on the outer circle, starting with EGD-e, followed by F2365, etc. L. monocytogenes strains are in blue; L. marthii is in green; L. innocua strains are in gold; L. welshimeri is in orange; L. seeligeri strains are in red; L. ivanovii subsp. londoniensis is in purple.
