Nutrient Metabolism Pathways Analysis and Key Candidate Genes Identification Corresponding to Cadmium Stress in Buckwheat through Multiomics Analysis

Fagopylum tatarium (L.) Gaertn (buckwheat) can be used both as medicine and food is also an important crop in barren areas has great economic value. Exploring the molecular mechanisms of response to cadmium (Cd) stress provide theoretical reference for improving buckwheat yield quality. In this study, perennial tartary DK19 was experimental material, its key metabolic pathways Cd were identified verified through transcriptomic metabolomic data analysis. investigation, 1798 metabolites non-targeted analysis containing 1091 up-regulated 984down-regulated after treatment. Kyoto Encyclopedia Genes Genomes (KEGG) differential significantly enriched galactose metabolism, glycerol phenylpropane biosynthesis, glutathione starch sucrose metabolism. Linkage detected 11 differentially expressed genes (DEGs) metabolism pathway, 8 candidate DEGs lipid 20 pathway. The results our study provided useful clues genetically resistance by analyzing mechanism tolerance buckwheat.
