Figure 6.

Confocal microscope observations of lettuce leaves: (a) tap water control, (b) 100 mM NaCl solution control, (c) B07 treatment with tap water, (d) B07 treatment with 100 mM NaCl, (e) P. terrestris strain PT22AV treatment with tap water, and (f) P. terrestris strain PT22AV treatment with 100 mM NaCl. Red and green fluorescence signals were captured after 400–600 nm laser excitation of plants pigments. Representative images of at least 10 fields are shown. Scale bar: 100 µm. Inset shows 3× magnification of stomata.
