PGPR VOCs can modulate infection severity of Arabidopsis seedlings by E. carotovora subsp. carotovora strain SCC1. Plants exposed to airborne chemicals released from eight ISR-inducing PGPR strains compared with a non-ISR Escherichia coli strain DH5α and water treatment; different letters indicate significant differences between treatments according to lsd at P = 0.05. Inset, Representative seedlings 24 h after E. carotovora subsp. carotovora infection and exposure to VOCs from GB03 (left) or DH5α (right).
