    Different effects of elevated carbon dioxide concentrations on plant growth


    While the increase in carbon dioxide content in the atmosphere promotes plant growth, it also reduces the nutritional value of plants, which may have a greater impact on nutrition and food safety worldwide


    Phosphorus is a fertilizer that is essential for plant growth, but the reserves of phosphorus worldwide are limited


    "We can't synthesize phosphorus in the same way we synthesize nitrogen," said Hatem Rouached, an assistant professor in the College of Agriculture and Natural Resources


    Rouached and his team observed that when plants are exposed to high concentrations of carbon dioxide, phosphorus levels in the plant's young shoots and leaves drop


    "We wanted to know why plants didn't absorb more phosphorus," Rouached said


    Rouached and his team dug deeper at the subcellular level and found that as an adaptive response to increased carbon dioxide levels, plants avoided excess phosphorus


    "What's really important in our findings is that when we try to force plants to add a lot of phosphorus to their chloroplasts, plants can't grow," Rouached said


    Rouached said: "This paper shows for the first time that we urgently need to discuss how to protect plant malnutrition from the effects of global carbon dioxide increases
