Fatty Acid 9/13-Hydroperoxide Lyase (9/13-HPL) in the cucumber plant is an enzyme that cleaves either 9- or 13-hydroperoxides of polyunsaturated fatty acids to form volatile C9 or C6 aldehydes respectively. Since these aldehydes may play a role in the plant’s defenses against pathogens (K. Matsui, et. al. Phytochemistry 67 (2006) 649-657), the enzyme is stress induced during vulnerable times such as when the plant is injured. In order to better understand how this enzyme is induced, we have developed a Real Time Polymerase Chain Reaction method to quantitate levels of 9/13-HPL mRNA. In initial experiments, the effect of mechanical wounding …
