(a) Change of motility-related gene expression. The expression of genes motA, cheA, cheW and fliA in E. coli MG1655 was measured by RT-qPCR after treatment with VOCs. The gene-expression level indicates the normalized gene level of VOC-treated sample to non-treated sample (control). The data shown are the averaged values (n=5, P=0.05). Error bars are defined as s.e.m. VOC-induced changes in (b) swimming and (c) swarming motility of E. coli. (d) Conservation of swarming motility in Gram-negative and Gram-positive bacteria. (e) Comparison of swarming motility in two different E. coli strains. The plates are representative of data obtained in triplicate. (f) E. coli mutant strains in which swarming motility was unchanged by VOCs. Supplementary Table S1 contains further information about these genes.
