IAA-degrading bacterial strains restore RGI induced by exogenous IAA.

<p>The upper panels show the images of seedlings grown on <sup>1</sup>/<sub>2</sub> strength MS agar plate supplemented with 100 nM IAA, taken 7 days after inoculation with or without bacteria. Scale Bar = 1.4 cm. NB, No bacterial inoculation. Red arrows indicate the original positions of the root tips at the time of bacterial inoculation. The other panels show images of the primary roots of <i>DR5</i>::<i>GFP</i> plants following bacterial inoculation at 1 and 3 days postinoculation. Scale Bar = 1 mm. Write arrow shows the GFP signals on root tip. Yellow arrow shows the GFP signals on root which was induced by exogenous IAA. BF, bright field.</p> <p>(PDF)</p>
