  1. Number of genes present in each family and group within the AP2/ERF superfamily in the plant species whose genome has been fully sequenced. A comparison of group and family-size between the grapevine AP2/ERF sequences identified in this study and those present in the Rice, Poplar, Arabidopsis Transcription Factor Databases are provided as ratios.
