Iron and zinc are important nutrients for plants, but too much of either can be harmful. A study looked at how iron and zinc interact in soybean plants. They found that high zinc levels can lead to iron deficiency symptoms, but increasing iron levels can counteract this. Excess zinc can also affect the uptake of other essential nutrients in soybeans. The study showed that the combination of high zinc and low iron activates specific genes in soybean roots and influences the activities of enzymes that help plants deal with stress. These findings shed light on how zinc and iron interact in plants and how excess zinc can mimic iron deficiency symptoms.
