Global climatic changes can have drastic impacts on plant species including severe consequences for the agricultural species productivity. Many of these species present important mutualisms with endophytic fungi that positively influence their performance. The present study evaluated whether the increases in CO<sub>2</sub> and temperature predicted for the year 2100 may cause changes in foliar carbon (C) and nitrogen (N) concentrations in soybean (<i>Glycine max</i>) and, consequently, the interactions with its endophytic fungi. The effects of elevated CO<sub>2</sub> and temperature were evaluated in four treatments in open-top chambers: (1) Control; (2) Increased Temperature; (3) Increased CO<sub>2</sub>; (4) Increased CO<sub>2</sub> and Temperature. Increased atmospheric CO<sub>2</sub> resulted in decreased foliar nitrogen concentration, while increased temperature increased it. A total of 16 taxa of endophytic fungi were identified based on sequencing <i><i>ITS</i></i> (Internal Transcribed Spacer) regions of rRNA subunits. Increased atmospheric CO<sub>2</sub> and temperature were observed to potentially modify the endophytic mycobiota of soybean plants. Results suggest the fungi species substitution as a consequence of changes in foliar nitrogen concentration and C:N ratio. Predicted climatic changes shall affect the plant and endophytes relationships, which will in turn affect the performance and resistance of soybean, one of the most important crops in the world.
