Figure Lengend Snippet: SEM micrographs of R. solanacearum using scanning electron microscopy (SEM). The round and intact cells are the control cells. (a) After treatment with 250 μg/mL bulk MgO, small holes can be seen in (b) , while the cells incubated with 250 μg/mL MgONPs exhibited deep craters and burst cells. (c) The lower screens are the enlarged parts of the upper yellow rectangles.

Article Snippet: To further explore the mechanism of the cellular interaction between the two MgO powders and R. solanacearum cells, the cell morphology was investigated by SEM (S-3400N, Hitachi, Japan) and TEM (JEM-2100, JEOL, Japan).

Figure Lengend Snippet: Antibacterial activity of the MgONPs and bulk MgO against R. solanacearum in vivo . The disease indexes of the tobacco plant were investigated after treatment with different concentrations (50, 100, 150, and 250 μg/mL) of (a) bulk MgO and (b) MgONPs. All the plants were tested in the set up in a randomized complete block design, and the error bars represents the SEM. The optical photographs 15 days after irrigation with (c) distilled water and (d) 250 mg/mL bulk MgO and (e) MgONPs were taken with a Nikon camera to survey the control efficiency.
