Relative abundance of ACS and ACO multigene family. Relative abundance of ACS (A-B) and ACO (C-D) multigene family members in roots and leaves of 3 weeks old Arabidopsis thaliana plants exposed for 0, 24 or 72 h to either 5 or 10 μM CdSO₄ or grown under control conditions in a hydroponic culture system. Data represent mean abundance of at least 4 biological replicates relative to the control (0 h, 0 μM CdSO₄) and with the abundance of the most highly expressed family member set at 1 under the control condition. (A) Relative abundance of ACS multigene family members in roots. (B) Relative abundance of ACS multigene family members in leaves. (C) Relative abundance of ACO multigene family members in roots. (D) Relative abundance of ACO multigene family members in leaves.
