Colonization of wild (Os-1), knockout (ΔipdC) or complementation (ΔipdCpipdC) strain Nostoc on roots of rice and wheat roots over time. Colonization was determined as chlorophyll-a (μg g-1 FW) in the roots. Graph represents data from three replicates in two independent experiments (data are mean ± SD; n = 6). Asterisk indicate a statistically significant difference (*p < 0.001; 3-way ANOVA) relative to wild and complementation strains.
