Fungal ITS indicator ASV uniquely associated with canola from C-C, C-W or C-P-B rotations in the soil, rhizosphere and root at Lacombe (A), Scott (B) and Swift Current (C). Sequences were identified using indicator species analysis and retained if both indicator values ‘A’ (specificity) and ‘B’ (sensitivity) were ≥ 0.7 and p ≤ 0.05 across both 2018 and 2019 growing seasons
