Non-metric multidimensional scaling (NMDS) of obtained transconjugants from conjugation experiments in the absence and presence of metals. The results show the ordination of different groups of transconjugants in two dimensions according to the similarities in their MDRPs. US: transconjugants were obtained using the urban site as the donor source. AS: Transconjugants were obtained using the agricultural site as the donor source. Treatments: A = without the addition of metals, B and C = 0.5 and 1 mM ZnSO4, respectively, D and E = 0.5 and 1 mM CuSO4, respectively.
