Copy numbers of AM fungal mtLSU (CN; per ng template DNA) in the roots of medic plants from the experiment with three harvests, as determined by the isolate-discriminating assays. Bars represent means of five replicates ± SD. Open bars, isolate CH growing alone; shaded bars, isolate CH in coexistence with PH5; dotted bars, isolate PH5 growing alone; black bars, isolate PH5 in coexistence with CH. Differences between means at P = 0.05 are indicated by letters (bars with the same letter are not significantly different).
