Quantification of growth promotion in A. thaliana with exposure to airborne chemicals released from six growth-promoting bacterial strains compared with a nongrowth-promoting E. coli strain DH5α and water treatment alone; representative examples of 10-day-old A. thaliana seedlings grown on I plates with airborne exposure to bacteria strains and water treatment are shown in Inset. The I plates were prepared as gnotobiotic systems so that the inoculated bacteria were the only microorganisms present.
