Fig. 3From: Systematic identification and analysis of frequent gene fusion events in metabolic pathwaysDistribution, variety, and frequency of fusion events in thiamin biosynthesis. The fusion architectures involving these genes as well as their identification data are given in (Additional file 1: Tables S3 A and B). The thiamin biosynthesis pathway enzymes, reactions, intermediates and fusion architectures are illustrated in this diagram following the same representation rules as in Fig. 2. The variety of fusions of each thiamin biosynthesis gene is shown on the top left insert. This variety is represented by a color range where the number of binary fusion events in which each gene participates (see Additional file 1: Table S3B), is proportional to the orange color intensity on the diagram (see left panel under compounds abbreviations section). The frequency of fusions of each thiamin biosynthesis gene is displayed on the top right insert. This frequency is expressed as a percentage and calculated as described in Methods. It is represented by a color range where the ratio for each thiamin gene mentioned above is proportional to the blue color intensity (see right panel under compounds abbreviations section)Back to article page
