Time course of the inhibition of isoprene emission (●) after feeding on 20 μmol of fosmidomycin. The inhibitor feeding through the petiole was started at time = 0. The photosynthetic rate of the same leaves during the experiment is also shown (○). Symbols and error bars represent means ± se(n = 6).

Effect of short-term (3 h, 300 nL L−1; left) and long-term (8 h, 100 nL L−1; right) ozone treatments on photosynthesis (A and B), stomatal conductance (C and D), and electron transport rate (E and F) of P. australis leaves. Each panel shows two pairs of bars representing photosynthesis of control (white) and ozone-treated (striped) leaves emitting isoprene (first pair) and nonemitting isoprene because of fosmidomycin feeding (second pair). Mean ± se (n = 3) is shown. Means were statistically separated by a Tukey's test, and means significantly different at the 5% level are identified by different letters.

Photochemical efficiency, estimated by the fluorescence parameter ΔF/F m′, during the long-term ozone treatment (8 h, 100 nL L−1 O3) in leaves emitting isoprene (black) or leaves in which isoprene emission was inhibited by fosmidomycin (white). Mean ± se(n = 6) is shown.

Effect of short-term (3 h, 300 nL L−1; A) and long-term (8 h, 100 nL L−1; B) ozone treatments on the non-photochemical quenching of P. australisleaves. Each panel shows two pairs of bars representing photosynthesis of control (white) and ozone-treated (striped) leaves emitting isoprene (first pair) and nonemitting isoprene because of fosmidomycin feeding (second pair). Mean ± se (n= 3) is shown. Means were statistically separated by a Tukey's test, and means significantly different at the 5% level are identified by different letters.

Effect of short-term (3 h, 300 nL L−1; A) and long-term (8 h, 100 nL L−1; B) ozone treatments on the content of H2O2 in P. australis leaves. Each panel shows two pairs of bars representing photosynthesis of control (white) and ozone-treated (striped) leaves emitting isoprene (first pair) and nonemitting isoprene because of fosmidomycin feeding (second pair). Mean ±se (n = 3) is shown. Means were statistically separated by a Tukey's test, and means significantly different at the 5% level are identified by different letters.

Effect of short-term (3 h, 300 nL L−1; A) and long-term (8 h, 100 nL L−1; B) ozone treatments on the content of MDA in P. australis leaves. Each panel shows two pairs of bars representing photosynthesis of control (white) and ozone-treated (striped) leaves emitting isoprene (first pair) and nonemitting isoprene because of fosmidomycin feeding (second pair). Mean ± se (n = 3) is shown. Means were statistically separated by a Tukey's test, and means significantly different at the 5% level are identified by different letters.
