Transcriptome Profiles of Leaves and Roots of Goldenrain Tree (<i>Koelreuteria paniculata</i> Laxm.) in Response to Cadmium Stress

Cadmium (Cd) pollution is a widespread environmental problem. In this study, we explored the transcriptome and biochemical responses of goldenrain tree (<i>Koelreuteria paniculata</i> Laxm.) leaves and roots to Cd stress. Leaf and root growth decreased substantially under Cd stress (50 m...
