  1. Numbers next to phyla names correspond to the number of complete genome sequences upon which the search was carried out (see additional file 2 for the complete list). +++, homologues could be found in more than 50% of the genome sequences; +, homologues could be found in less than 50% of the complete genome sequences; -, no homologues found; *, only one genome sequence from these phyla was analyzed.
