The effects of Hpa1 on concentrations of phytohormones ethylene (a) and gibberellin (b) in Arabidopsis, tomato, and rice plants. 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. Concentrations of both hormones were determined at the indicated time points. Data are shown as mean values ± SD from three experimental repeats (15 plants per repeat). Different letters on tops of bar graphs indicate significant differences by the statistical analysis
