Figure 5From: Detection of horizontal transfer of individual genes by anomalous oligomer frequenciesComparison of CGS and GC methods. (A) Discrimination values based on CGS scores and GC scores were calculated using as targets the genomes of Group 1 cyanobacteria (□) Ana, (∆) Mar, and (○) Syn; of Group 2 cyanobacteria (+) Pma, (-) Pmt, and (×) Syw; and of (♦) Tel, contaminating them to a level of 3% with the same genes from up to 25 different organisms. Each point is the average of three trials. The values in the dotted box uses contaminating genes from (-) Gvi (GC% of 62%), (♦) Gvi, Syw (GC% of 59%), and Cya (GC% of 60%), (□) Pmm (GC% of 31%). (B) The same GC scores as in panel A are shown related to the difference in GC% of the donor and target genomes. (C) The same discrimination values as in panel A are shown related to the difference in GC% of the donor and target genomes. The identities of the genomes and values of both methods are provided in Additional file2.Back to article page
