Ethylene production of WT, acs mutant plants under Fe-sufficient (+Fe) and -deficient (−Fe) conditions. Ten-day-old seedlings were transferred to Fe-sufficient (50 μM EDTA-Fe) or -deficient (0 μM EDTA-Fe) nutrient solutions. Ethylene accumulated over a 24 h period from 10 seedlings in the headspace of GC vials was measured at 4 day after the treatment. Data are shown as the mean ±SEM (n = 3). Columns marked with “*” indicate a significant difference (P < 0.05), and “**” indicate a highly significantly difference (P < 0.01).
