FIGURE 4.

Effect of inoculation of the wild type strain P. fluorescens C7R12 (WT pvd+) and of PL1 its pvd− mutant (Mutant pvd−) on (A) biomass, (B) iron concentration, and (C) iron content in two pea cultivars, tolerant (T) and susceptible (S) to iron chlorosis (n = 3). Error bars represent the s.d. of the mean. P value was calculated using one-way ANOVA between the inoculation treatment and the non-inoculated control within a same plant compartment and in a same pea cultivar. ^∙p < 0.1; *p < 0.05.
