  1. CK rhizosphere soil from control plants without R. solani AG8 infection, R rhizosphere from plants infected with R. solani AG8 in cycle 1, B rhizosphere from plants with “bad” treatment (the worst wheat root disease), G rhizosphere soil from plants with “good” treatment (the least wheat root disease). The values are means ± standard error. Different letters indicate significant differences for indices (p ≤ 0.05, Tukey test). The statistical contrasts were performed separately among cycles and treatments
