CO₂ concentration (mean ± SE) measured for the 11 fungi and their respective controls when a enclosed alone, and b co-cultivated with Arabidopsis thaliana seedlings for 7 and 14 days. Pearson correlation between the average plant dry weight (mean ± SE) upon co-cultivation for 14 days and c the average CO₂ concentration (mean ± SE) measured after 14 days when the fungi were enclosed alone, and d the average CO₂ concentration (mean ± SE) measured after 14 days when the fungi were co-cultivated with plants. Blank, empty Petri dish; C4, C7 and C10, medium alone pre-incubated for 4, 7, and 10 days; Ci,  Chaetomium indicum; Fo47,  Fusarium oxysporum 47; For,  F. oxysporum f.sp. raphani; Mp,  Mucor plumbeus; Pl,  Phoma leveillei; Rs,  Rhizoctonia solani; Ss,  Sclerotinia sclerotiorum; Tv,  Trichoderma viride; Ua,  Ulocladium atrum; Vd,  Verticillium dahliae; Vl,  Verticillium longisporum. Upon co-cultivation with plants, each fungal volatile exposure was replicated 2–7 times, and when the fungus was incubated alone, each volatile exposure was replicated 5–8 times. Due to fungal overgrowth on plant compartment, exposure with R. solani volatiles was excluded from the analysis upon co-cultivation with A. thaliana. Main effects of the fungal volatiles and exposure time were tested using ANOVA. Detailed output of the pairwise differences between the fungal volatile exposures is reported in the electronic supplemental material (Fig. S5)
