Modeling predictions are based on the eight strain training set (see 'Mathematical development of a finite supragenome model'). The number of genes observed in all strains levels off to an asymptote that corresponds to a core set of genes. The rate of increase in total genes decreases, but does not level off due to the discovery of rare genes.<p><b>Copyright information:</b></p><p>Taken from "Characterization and modeling of the core and supragenomes based on the complete genomic sequences of Rd and 12 clinical nontypeable strains"</p><p>http://genomebiology.com/2007/8/6/R103</p><p>Genome Biology 2007;8(6):R103-R103.</p><p>Published online 5 Jun 2007</p><p>PMCID:PMC2394751.</p><p></p
