Plant growth response to treatment with Pseudomonas sp. A-2. (a) Plant morphology of A. thaliana was observed 1, 3, 5, and 7 days after treatment (DAT) with a suspension of the A-2 strain applied at the middle of the vertical plate. (b) Fresh weight of A. thaliana was measured DAT 1, 3, 5, and 7 with the A-2 strain. (c) Lateral root number and (d) root thickness were measured DAT5 and DAT7 with the A-2 strain. (e) Growth differentiation based on the treatment position of the A-2 strain: growth was assessed DAT7 with a suspension solution applied at the top of the vertical plate. (f) Morphology of N. tabacum was observed DAT14 with a suspension of the A-2 strain applied at the middle of the vertical plate. (g) Fresh weight of N. tabacum was measured DAT14 with the A-2 strain. (h) Plant morphology of peanut plants DAT14 with a suspension of the A-2 strain applied to the soil. (i) Fresh weights of peanut plants were measured DAT14. Significant differences between control (C.) and Pseudomonas sp. A-2 treated plants (P. A-2) were evaluated using Student’s t-test : *P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001. The results are presented as the mean ± standard deviation (n = 3).
