Fig. 5. Adequacy of the sequences analyzed to reveal the whole diversity in the AM fungal community. Estimates of AM fungal community diversity as a function of sampling effort in the T. repens roots for the first sampling A1 (a) and second sampling A2 (b). Rarefaction curves are computed from 300 replicates of bootstrap (dashed) and random combinations of 1 to N sequences (plain), where N is the effective number of sequences analyzed for heavy RNA (red), normal RNA (blue), and DNA (black).
