Characterization of the IAA-Producing and -Degrading Strains Regulating Growth of the Common Duckweed ( L.).

The rhizosphere represents a center of complex and dynamic interactions between plants and microbes, resulting in various positive effects on plant growth and development. However, less is known about the effects of indole-3-acetic acid (IAA) on aquatic plants. In this study, we report the characterization of four strains isolated from the rhizosphere of the common duckweed () with IAA-degradation and -utilization ability.
