IAA-degrading bacterial strains restore RGI caused by Syncom110 in <i>Arabidopsis</i> seedlings.

<p>(A) The complex synthetic bacterial community (comprising 110 bacterial strains, see <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.3002921#pbio.3002921.s019" target="_blank">S4 Table</a>) induced RGI was partially alleviated by introducing IAA-degrading strains. Boxplot middle line, median primary root elongation; box edges, 25th and 75th percentiles; whiskers, from the minimum to the maximum value. Each point represents a biological replicate, with 4 to 6 replicates were used in this experiment. (B) The images of <i>Arabidopsis</i> seedlings grown on half-strength MS agar plates inoculated with or without bacteria at day 7. Red arrows indicate the original positions of the root tips at the time of bacterial inoculation. NB indicates no bacterial inoculation. Significant differences compared with NB group were determined using Student’s <i>t</i> test: *<i>P</i> < 0.05, **<i>P</i> < 0.01, ***<i>P</i> < 0.001. Numerical values that underlie the data displayed in the panels are in <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.3002921#pbio.3002921.s021" target="_blank">S6 Table</a>.</p> <p>(PDF)</p>
