Abstract Climate changes, feature as the increased temperature and concentration of CO₂ in the atmosphere, substantially affect the agricultural production. Soybean (Glycine max) is an important oil crop, but little is known about the gene regulation of soybean leaves response to elevated CO₂ and warming, which were important to gain insights of soybean adaption and feedback to climate change. In this study, an OTC (open top chamber) experiment was performed to simulate the conditions of elevated CO₂ and warming. Soybean leaves at the full pod stage (R5) were collected for transcriptome analysis. The results showed that 5 646 differentially expressed genes (DEGs) can be annotated as 44 functional terms by Gene Ontology (GO) analysis, among which, cell processes, cell and binding had higher enrichment degree. The Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis found that the expression of 14 differentially expressed genes which were mainly related with the regulation of photosynthesis pathway increased under elevated carbon dioxide condition. However, the expression of 16 out of 17 differentially expressed genes which were mainly related with fatty acid metabolism pathway increased under elevated CO₂ and warming conditions. Warming did not induce any significant changes of differentially expressed genes. The results would provide theoretical basis for further exploring the molecular mechanism of soybean response to future climate changes.
