Transcriptome Analysis Revealed the Differential Molecular Response Mechanisms of Roots, Stems, and Leaves in Mung Bean to Cadmium Stress

To acquire a comprehensive understanding of the different plant organ molecular mechanisms in response to cadmium (Cd), transcriptome analyses of mung bean roots, stems, and leaves exposed to 100-μM Cd for 1, 5, and 9 days were performed. A total of 13,055, 8189, and 6705 differentially expressed genes (DEGs) were obtained in roots, stems, and leaves, respectively. The analysis of DEG enrichment and functional profiling showed that the upregulated DEGs in roots were significantly ( p
