Experimental data on soybean physiology and immune responses to different phytopathogens under elevated CO₂

This dataset includes results from five major experiments that explore the effects of elevated CO₂ on soybean physiology and its interactions with different plant pathogens, including Pseudomonas syringae, bean pod mottle virus, soybean mosaic virus, Fusarium virguliofrme, and Pythium sylvaticum in .csv spreadsheets. Raw data were collected from soybean (Glycine max cv. Williams 82) plants grown in CO₂-controlled environment chambers at the Iowa State University Enviratron facility. All chambers were set to the same conditions that mimic mid-June weather in central Iowa, except for CO₂ levels, which were 419 ppm in chambers set to ambient CO₂ (aCO₂) conditions and 550 ppm in elevated CO₂ (eCO₂) conditions.
