Multiomics Combined with Expression Pattern Analysis Reveals the Regulatory Response of Key Genes in Potato Jasmonic Acid Signaling Pathways to Cadmium Stress

Jasmonic acid (JA) is an endogenous phytohormone that regulates plant physiological metabolism and stress response processes, either independently or through hormone crosstalk. Our phytohormone assay and transcriptome-metabolome analysis revealed the key genes and metabolites involved in the JA pathway in response to 0-250 μM cadmium (Cd) in potato seedlings. Transcriptome gene set enrichment and gene ontology analysis indicated that JA-related genes were significantly enriched. Specifically, members from the
