Frequencies of transformation in selected bacterial species with different DUS dialects displaying cross-species DUS transformation ratios. Experiments were performed at least three times.
1 transformation frequency relative to the AT-DUS transformation frequency in the same species.
2 erythromycin-resistant transformants could not be detected in any of all experiments.
3 cumulative number of CFU in all performed experiments.
4 not applicable.
SD = standard deviation.
