Frame-shift mutation and transposition rates in transgenic Arabidopsis detector lines after infection with different Agrobacterium strains, E. coli and heat-killed bacteria for 48 h. a. Frame-shift mutations rates in line G10. b. Tag1 transposition rates. Bars indicate the standard error of the mean of three biological repeats, each consisting of about 60–80 plants. Numbers on top of the bars show the respective mean values. Numbers at the bottom show the respective number of seedlings analysed. Vertical axis shows the mutation rates. a, b, c, d, e, fMeans not followed by the same letter are significantly different at 5 % level as determined by Duncan’s multiple range test. C, control; HK-A, heat-killed-Ach5; E, E. coli; HK-E, heat-killed E. coli
