Table 1.

Two-way ANOVA table summarizing the interactive effects of cadmium treatment levels (0, 10, 50, 100, and 250 mM), bacterial treatment (wild-type ACC deaminase-producing bacteria, its isogenic ACC deaminase-deficient mutant, and no-bacterial control), and their interaction on plant fresh, dry weight, and shoot ethylene concentration in A. thaliana. One linear model was fitted separately for each dependent variable
