Alteration of root elongation in Arabidopsis thaliana seedlings by Serratia M24T3. Seeds were germinated in a line on half strength MS agar and 50 μl of bacterial suspensions added on sterile paper. a Primary root elongation was inhibited by suspensions of the strain M24T3 wild type. b The root elongation in control with LB broth without strain M24T3 was not inhibited. c The length of shoots (black bar) and roots (gray bar) and the number of lateral roots (stripes bar) were compared between plants with or without M24T3. Bars within the different symbols (a,b; a′,b′; a″,b″) mean statistically different between each other (p < 0.05)
