Ethylene production and expression of ACS2 and ACS6 in mpk3 and mpk6 mutants. (A) Ethylene production in mpk3 and mpk6 mutants. (B) Transcript abundances of ACS2 and ACS6 genes in mpk3 and mpk6 mutants. 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 days after the treatment. qRT-PCR was conducted using RNA extracted from whole seedlings at 7 days after –Fe 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).
