Physiological and biochemical responses in a cadmium accumulator of traditional Chinese medicine Ligusticum sinense cv. Chuanxiong under cadmium condition
1. Under 25 μM Cd, it was the hormesis effect on the growth of L. Chuanxiong.
2. Seedlings increased the thickness of root cell wall to chelate and fixate Cd.
3. Seedlings enhanced NH4+ absorption and assimilation, thereby increasing chlorophyll content.
4. Seedlings mainly reduced oxidative stress caused by Cd stress through the GSH/GSSG cycle.
