Figure 2

Indole-3-acetic acid (IAA) relative production by R. tropici CIAT 899 wild type, and by the nodD1 and nodD2 mutants. Bacteria were grown in TY medium containing tryptophan in absence and presence of apigenin (3.7 μM) or NaCl (300 mM). Supernatants were taken 96 h after the addition of flavonoid or salt. IAA production was calculated relative to the production without inducing molecules of the wild type strain by using the Mann–Whitney non-parametrical test. The asterisks indicate a significant different at the level α = 5%. Black bars: CIAT 899. Light gray bars: nodD1 mutant. Dark gray bars: nodD2 mutant.
