Transcriptomics combined with physiological analysis reveals the mechanism of cadmium uptake and tolerance in Ligusticum chuanxiong Hort. under cadmium treatment.

ABSTRACT:

Introduction

Ligusticum chuanxiong Hort. is a widely used medicinal plant, but its growth and quality can be negatively affected by contamination with the heavy metal cadmium (Cd). Despite the importance of understanding how L. chuanxiong responds to Cd stress, but little is currently known about the underlying mechanisms.

Methods

To address this gap, we conducted physiological and transcriptomic analyses on L. chuanxiong plants treated with different concentrations of Cd²⁺ (0 mg·L^-1, 5 mg·L^-1, 10 mg·L^-1, 20 mg·L^-1, and 40 mg·L^-1).

Results

Our findings revealed that Cd stress inhibited biomass accumulation and root development while activating the antioxidant system in L. chuanxi
