Schematic of Experimental Design (IMAGE) American Phytopathological Society Caption Three-day-old seedlings of Setaria viridis A10.1 were inoculated with either Herbaspirillum seropedicae SmR1 (fix+) or SmR54 (fix?), while the control (CTRL) plants were uninoculated. The plants grew for 2 weeks after inoculation under greenhouse conditions. The roots and leaves were harvested. Roots from plants that were inoculated with SmR1 or SmR54 were analyzed by fluorescence microscopy. Credit Beverly J. Agtuca, Sylwia A. Stopka, Thalita R.
