Fig. 2. (a) Total biomass for A. virginicus in non-mine soil vs. mine soil, by inoculum type. FM is the fungal community derived from mine soil. FN is the fungal community
derived from non-mine soil. F0 excludesAMfungi. Biomass includes both plant ecotypes (p < 0.0001). (b) Percent root colonization for fungal ecotypes in Andropogon virginicus.
p-Value for 2-way interactions between soil and fungi is 0.0148, reflecting the mine fungi’s much higher root colonization in mine soil than in non-mine soil. The non-mine
ecotype did slightly better in mine soil. Error bars are ±0.04 and may not be readily visible due to their small size.
