The notion of ranking genomes with the Google Scholar service originated from the need to build a subset of all available genomes for testing purposes (in this case, an algorithm for building orthologous relationships). We did not want to design and implement a complicated scheme for selecing genomes. Thus, we decided to submit each genome to Google Scholar and simply rank it based on the number of literature articles returned.
The number of literature articles associated with any given genome turned out to be an excellent method for assessing the scientific interest in this organism. As expected, Escherichia coli is the top-ranking bacteria, followed by the human pathogen, Staphylococcus aureus and several other well-studied organisms.
Along with incorporating new genomes, the google ranking of every genome in MiST2 is also updated each month.
