PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email info@biomedcentral.com, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

Supra-genome vs. pangenome

What is the difference between the "Supra-genome" mentioned in this article, and the "pangenome" first used to describe several sequenced Streptococcus agalactiae genomes, back in 2005? I can find the phrase "pan-genome" 16 times in PubMed, but "Supra-genome" is found only 3 times - once in this paper, and twice other by papers from the same group. Can't we reach an agreement on what to call all the combined genes in a set of sequenced genomes from the same species?

Why should it be called "pan-genome" for Burkholderia, Campylobacter, E. coli, Streptococcus, and Vibrio, but for Haemophilus it is the "supra-genome"?

Along with Tim Read, I wrote an editorial overview with the title "Opening the PanGenomics Box" in 2006 for Current Opinion in Microbiology.
