Characteristic responses of isoprene emission and net assimilation rates and stomatal conductance to changes in ambient CO2 concentration (A) and acetaldehyde emission (B) in a hybrid aspen leaf before (0–1,800 s) and after (1,800–4,000 s) application of 150 μm of the specific PEPC inhibitor diethyl oxalacetate (DOA), and DOA dose response at ambient CO2 concentration of 400 μmol mol−1 (C). Data presentation is as in Figure 3.
