^aClassification of individual plants according to the Ds excision sites isolated. A: number of plants with “gc” footprint. B: number of plants showing unique footprints including “restoring” excision products. C: number of plants with multiple footprints. D: sequence was unreadable distal to the Ds excision site.

^bThe three independent plant lines analyzed for each transposase are, with the exception of 29 (Ds5), all derived from Ds starter line Ds24.

^cNumber of plants analyzed for excision of Ds.

^dNumber of individual plants with empty Ds donor sites.

^eΣ = total number of AcTPase and AcTPase_4x plants and excisions, respectively.
