Transcriptomic Analysis of Gene Expression Patterns in Paulownia fortunei Under Chromium and Copper Stress

Research on the metal accumulation capacity and soil remediation potential of P. fortunei has predominantly focused on physiological levels, with a paucity of in-depth analysis at the molecular level regarding how this species responds to heavy metal stress. The genomic responses and molecular mechanisms of P. fortunei under heavy metal stress are not yet fully understood. The present study therefore aims to sequence the transcriptome of P. fortunei seedlings under Cu and Cr stress, in order to identify differentially expressed genes (DEGs) and further construct gene co-expression networks associated with response mechanisms at the molecular level.
