Multi-omics integration uncovers mechanisms of chromium tolerance in Cosmos sulphureus.
Chromium (Cr) is a highly toxic, mobile heavy metal pollutant that is easily taken up by plants, whereas the Cr tolerance and molecular mechanisms underlying Cr stress responses in C. sulphureus remain poorly elucidated. In this study, we comprehensively investigated phenotypic, physiological, transcriptomic, and metab...
