Abstract:
Soil heavy metal pollution affects the normal growth and development of plants,and even causes potential harm to human health.Metabolomics,as an important part of system biology,provided a reliable basis for studying the response and defense mechanism of plants to heavy metal stress,and provide reference for guaranteeing the quality and safety of agricultural products.Multiple research methods of plant metabolomics have been developed to meet different research needs.Metabolomics studies on the mechanism of toxicity of heavy metals in plants mainly focused on toxicity mechanism,stress tolerance mechanism and differences in heavy metal accumulation capacity.Metabolomics studies have shown that the mechanism of heavy-metal toxicity varies in different plants or under different conditions.Heavy metal stress can affect a variety of metabolic pathways in plants,and may lead to the reduction of plant growth and photosynthetic capacity.It may also activate the defense mechanism of plants,such as regulation of DNA repair ability,plant hormone level,and antioxidant activity,and reducing the bioavailability of heavy metals,which can play a role in detoxification.
