- Researchers in France have discovered that zinc plays a crucial role in the health of legume crops.
- zinc aids in plant’s nitrogen fixation, a process where atmospheric nitrogen is converted into ammonia, an essential nutrient for plants.
- Legume crops form a symbiotic relationship with rhizobia, a bacterium that fixes atmospheric nitrogen in root nodules.
- These nodules are sensitive to environmental factors such as temperature, drought, flooding, soil salinity, and high soil nitrogen levels.
- The researchers discovered that legumes also use zinc as a secondary signal to integrate environmental factors and regulate nitrogen fixation efficiency.
- The mechanism works due to a transcriptional regulator called Fixation Under Nitrate (FUN).
