We have started using this close-focus, computer-driven imaging system to examine the kinetics of ethylene growth responses in other plant species (Kim et al. 2012). In addition to uncovering differences between various species, we hope to combine this approach with molecular biology to elucidate details of ethylene signaling in other plants with a focus on agriculturally and horticulturally important species.

• Back lighting was provided by an infrared LED
• One frame was taken every 5 minutes for 6 hours
• The presence of 10 mL/L ethylene is indicated when the image shading inverts (this was done digitally)
