Molecular and Physiological Mechanisms Underlying Cadmium Tolerance and Hormesis Effect in Roots of Ligusticum sinense cv. Chuanxiong
Ligusticum sinense cv. Chuanxiong (Chuanxiong) is threatened by excessive cadmium (Cd), affecting its safety and quality. This study aimed to characterize Cd distribution in Chuanxiong roots (subcellular level) and clarify its key response mechanisms to Cd stress, using ICP-MS, SEM-EDS, and transcriptome analysis.
