Analysis of differentially expressed proteins and related metabolic pathways in response to lead stress in the leaves of Pogonatherum crinitum.

Proteomics provides an essential means of explaining the mechanisms underlying gene expression regulation. The proteomic mechanisms by which heavy metal hyperaccumulators respond to lead (Pb) stress remain largely unclear. To this end, we examined Pogonatherum crinitum (Thunb.

Transcriptomics-based analysis of genes related to lead stress and their expression in the roots of .

Revealing plants' tolerance and transport genes to heavy metal stress play an important role in exploring the potential of phytoremediation. Taking the heavy metal lead (Pb) hyperaccumulator plant (Thunb.) Kunth as the research object, a hydroponic simulation stress experiment was set up to determine the physiological indicators such as antioxidant enzymes and non-enzymatic antioxidants in the roots of under different Pb concentrations (0, 300, 500, 1000, 2000 mg·L).
