(A) Relative expression of Arabidopsis ERF1, 4, 5, 8, 9, 11,104 and 105 in 10-day-old light-grown seedlings of the wild type (WT) and CPR5-overexpression lines (OX3, OX7), respectively. (B–G) Relative expression of Arabidopsis ERF1, 8, 9, 11, 104 and 105 in 10-day-old light-grown seedlings of the wild type (WT), cpr5-T3, and CPR5-overexpression lines (OX3, OX7), respectively. Plants were grown on 1/2×MS medium for 10 days, then treated with or without ACC (100 mM) for 4 h. Values are mean ±SD; *P<0.05, ** P <0.01.
