Abstract
High-voltage electroporation was used to transform Agrobacterium tumefaciens strains A136 and A348, reaching the efficiency of 1-3 × 108 transformants/μg DNA. Transformation frequency was dependent on the electrical field strength and the pulse length. No significant reduction in transformation efficiency was observed when the transforming DNA contained sites sensitive to endonuclease AtuCI of A. tumefaciens.
