The development of purple color in tubes treated with crystal violet, indicative of biofilm formation (right), and the graph demonstrating the increase in IAA production in a period of 5 days by Sub1 cultures (left). The negative control of biofilm formation is provided in Supplementary Figure 5. Note: the control goes along the X-axis.
