Fig. 4.

The effect of Hpa1 on photosynthesis in leaves of Arabidopsis, tomato, and rice. Ten-day-old plants grown in pots were treated by spraying over tops separately with an aqueous Hpa1 solution and with pure water or an aqueous EVP solution. Five days later, measurements of net photosynthesis (A _N) rates were performed on the second youngest leaves. Data are shown as mean values ± SD from three experimental repeats (15 plants per repeat). Different letters on SD bars indicate significant differences by two-tailed ANOVA and LSD test (P < 0.01)
