Total carbon transferred from wheat (Triticum aestivum L., cv. Avalon, Cadenza, Skyfall) to fungal mycelium during the course of ¹⁴C labelling experiment (a), and per cent of carbon fixed during the labelling period which was recovered in the static core at harvest (%) (b). Plants were grown at ambient (440 ppm, white boxes) and elevated (800 ppm, grey boxes). Bars sharing letters are not significantly different, where p > .05 (ANOVA, Tukey post hoc test). Data were log₁₀ transformed where data assumptions were not met. N.S.D., not significantly different
