Overview of data showing that Ler is not insensitive to ethylene and that the endogenous ethylene production does not saturate hyponastic growth

The ethylene and ACC production in Col-0 was significantly higher (P < 0.001) compared to Ler, while the ethylene-induced ERS2 expression was higher (P < 0.05) in Ler compared to Col-0. The petiole angle is the difference in petiole angle between 1-MCP pretreated and nonpretreated plants. Data are means and se of four to eight replicate plants. FM, Fresh mass.
