Intrachromosomal somatic homologous recombination rates in Arabidopsis detector lines 651 and R2L1, after infection with different Agrobacterium strains, E. coli and heat-killed bacteria for 48 h. a. Line 651 b. Line R2L1. Bars indicate the standard error of the mean of three biological repeats, each consisting of about 140–160 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, bMeans 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
