Fig 3. Effect of some bacterial isolates from G1 and G3B on the DR5::uidA reporter gene for auxin responses in Arabidopsis thaliana.

(A) Qualitative analysis of uidA gene expression in A. thaliana transgenic lines inoculated with bacterial isolates. Values were obtained by comparing the treatments with the control without inoculation. A scale with a range of 4 to -4 was established for this analysis. Higher values and a more intense blue color indicate higher expression compared to that in the control. The orange color indicates an absence of gene expression (NE). (B) Representative photographs of the shoot, lateral root zone and meristem of the primary root of transgenic DR5::uidA seedlings inoculated with bacterial strains. Scale bar: Petri dishes = 1 cm, plant zones = 500 μm.
