Autophagy: The Unlikely Hero That Balances Zinc and Iron in Plants
Published:22 Aug.2021    Source:Meiji University

Nutrient imbalances can adversely impact crop health and agricultural productivity. The trace elements zinc and iron are taken up by the same "transporters" in plants; so, zinc deficiency can result in excess uptake of iron. How does the plant cope with this imbalance? Researchers from Meiji University, Japan, reveal that autophagy, the process of intracellular self-degradation, may have an unexpected role in restoring zinc-iron balance in plants.

 
A balance of nutrients and minerals in the soil is essential for the optimal growth of plants. A deficiency or surplus of specific nutrients can have detrimental effects on the growth and health of plants, thus affecting the overall quality and quantity of agricultural produce. Nutrient imbalances have become increasingly prevalent, given the excessive heavy metal contamination from industrial activities.
