metagenmics analyses of root microbiome associated to black poplar

. At the end of the experiment, we observed that the compost amendment strongly increased the foliar size but did not affect significantly the Zn accumulation in plant. Furthermore, the rhizo-microbiome communities (bacteria and fungi), investigated through NGS, highlighted how a diversity increased in all treatments compared to the untreated N12 saplings. Soil compost amendment, as well as Zn pollution, strongly modified the bacterial rhizo-microbiome structure. Conversely, the variation of the fungal rhizo-microbiome was only marginally affected by soil Zn addition, and only partially impaired by compost. Nevertheless, substantial alterations of the fungal community were due to both compost and Zn.
