Streptomyces exhibit increased colonization of sorghum roots under drought. Confocal fluorescence (A1 and A3) and bright-field (A2 and A4) imaging of colonization of mCherry-tagged Streptomyces strain Sc1 on control (Top) and drought-treated (Bottom) roots of genotype RTx430. (Scale bars: 50 μm.) Violin plots of the fluorescence intensity are measured using confocal fluorescence microscopy across 24 control (green) and 24 drought-treated (orange) root samples. AU, arbitrary unit.
