Genetic and chemical analyses for the interactive effects of ethylene and gibberellin on Hpa1-enhanced photosynthesis, EXP expression, and growth of Arabidopsis.
a Ten-day-old WT and etr1-1 plants were treated separately with pure water or an aqueous EVP solution and with aqueous solutions of Hpa1, PBZ, and a Hpa1 + PBZ mixture. b Ten-day-old WT and ga5-1 plants were treated separately with pure water or an aqueous EVP solution and with aqueous solutions of Hpa1, 1-MCP, and a Hpa1 + 1-MCP mixture. a, b Five days after plant treatment, analyses of A
N rates and EXP expression were performed on the second youngest leaves. Fresh weight of plants was scored 10 days after treatment. Data shown are mean values ± SD from three experimental repeats (15 plants per repeat). Different letters on bar graphs indicate significant differences by the statistical analysis
