SAY09 exposure affects the Cd accumulation in Arabidopsis under Cd stress. Six-day-old seedlings were cultured on 1/2 MS agar medium with 50 μM CdCl2, after 12 d of exposure to SAY09 VOCs, and non-exposed plants as the controls. Then, these plants were used to measure Cd concentration (A), HC1 (B), and pectin (C) in root cell wall, and Cd concentration in HC1 (D) and pectin (E). Different letters above each bar indicate significant difference at p < 0.05.
