Upregulation of N. benthamiana MIGs after 18 h methanol treatment.

*Methanol treatment was executed by exposing two plants to methanol vapor (methanol applied to the filter paper) in a sealed desiccator. The data shown represent five independent experiments. The standard errors are indicated.**Methanol content in the headspace of two intact N. benthamiana plants (10.0±1.0 g) in a pot (width, 9.5 cm; depth, 9.5 cm) with soil (198.0±20.0 g) after an 18-h incubation.***Methanol content in the headspace of two intact non-treated N. benthamiana plants after an 18-h incubation.
