Prokaryotic (a) and fungal (b) diversity in compost, roots, and tailings incubated under different treatments: tailings (T), tailings with added compost (TC), tailings with a plant (TP), tailings with a plant and added compost (TPC), tailings with a plant inoculated with endophytes (TPE) and tailings with a plant inoculated with endophytes and added compost (TPEC). Initial materials included initial tailings (Tin), initial compost (Cin), seeds inoculated with beneficial endophytes (S+e), and seeds treated with sterile medium (S-e)
