Transcriptomic insights into nitrogen-regulated cadmium absorption and accumulation in Spirodela polyrhiza: toward enhanced phytoremediation strategies for cadmium-polluted environments.
Researchers discovered that raising nitrogen levels in water helps duckweed absorb and neutralize the toxic metal cadmium more effectively, revealing the specific genes and molecular switches behind this interaction. This opens a practical path to using fertilized duckweed ponds as low-cost cleanup systems for cadmium-contaminated water.
