Fig. 7From: Melatonin confers heavy metal-induced tolerance by alleviating oxidative stress and reducing the heavy metal accumulation in Exophiala pisciphila, a dark septate endophyte (DSE)The effects of the overexpression of EpTDC1 and EpASMT1 decreased Cd accumulation on Cd concentration in Arabidopsis thaliana whole plants, shoots, and roots. The A. thaliana seedlings at the four-leaf stage of wild-type (WT), EpTDC1–1/EpTDC1–2, and EpASMT1–1/EpAMST1–2 were transferred to soil containing 0, 20.0, and 40.0 mg kg− 1 Cd2+, respectively for 30 d. Data are means ± SD (n = 4). Columns with different letters denote significant differences at P < 0.05 according to Duncan’s multiple range testBack to article page
