Identification of recent ABC gene duplication events in all genomes examined
| Species | Tandem duplication | a Blocks of duplication | Total number of duplicate ABCs |
|---|---|---|---|
| A. thaliana | 10 | 4 | 35b (27) |
| O. sativa | 11 | 2 | 29 (20) |
| S. lycopersicum | 13 | 2 | 32 (17) |
| S. tuberosum | 19 | 5 | 56 (25) |
| V. vinifera | 14 | 6 | 52 (31) |
| V. carteri | 1 | - | 2 (3) |
| S. cerevisiae | - | - | - (−) |
| Total | 67 | 20 | 205 |
aA block of duplication was defined if more than one gene was involved in the duplication. bThe percentage of duplicate ABC transporter genes on total of gene sequences analysed is reported in brackets.
