Fig. 4From: Costs and benefits of natural transformation in Acinetobacter baylyi Natural transformation frequencies of A. baylyi wildtype and DNA recombination-impaired mutants. Transformation frequencies were obtained in liquid transformation experiments with genomic homologous DNA (0.1 μg ml−1) containing a kanamycin resistance marker gene and are given as means with 95% confidence intervals. The initial recipient titers are listed in (Additional file 1: Table S4)Back to article page
