Fungal genera in bulk soil, root-associated soil and the rhizosphere of lettuce (cv. Tizian) differing significantly (FDR < 0.05) in relative abundance depending on long-term organic (HU-org) and mineral (HU-min) fertilization strategy (A) in the absence and (B) in the presence of Rhizoctonia solani AG1-IB (Rs). Mean ± standard deviation of taxa with >0.5% relative abundance is displayed. Bold numbers indicate significant enrichment.
