Takeaways
As the world's population grows, feeding everyone will grow more challenging. Advances in technology in the past have made today's population possible, but future advances may be needed, especially in the face of an increasing concentration of carbon dioxide in the atmosphere.
Soil microbes that partner with crop plants for the benefit of each may be part of the solution. One option to explore is a group called mycorrhizal fungi, which associate with plant roots to extend their nutrient-gathering ability, in exchange for carbon compounds produced by photosynthesis. This study examined the influence of increased carbon dioxide in the atmosphere on the interaction of several varieties of wheat with these fungi.
