Table 2 Identification of recent ABC gene duplication events in all genomes examined

From: Genetic variability and evolutionary diversification of membrane ABC transporters in plants

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 - - - (−)

  1. 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.
