Comparison of the syntenic region and duplication history of the AP2/ERF pepper, tomato, and potato genes. A-B Micro-synteny analysis of AP2/ERF genes in the subgroup B2 A and B3 B on chromosomes 1 and 4. The gene IDs in the syntenic region are represented and the orthologous gene is linked with the line. The genes colored with grey indicate orthologous genes that are not AP2/ERF genes. C Heat map of the number of genes with orthologous relationships. The number of genes having orthologs in three, and two species are displayed on A and B, respectively. The number of genes with no orthologs is represented on the C. D Histogram showing the duplication history of AP2/ERF genes. The color of the bar indicates an ortholog relationship between the three species. E The distribution of duplication history of AP2/ERF. The shapes and colors indicate species and ortholog relationships between the three species, respectively
