These results were corroborated by PERMANOVA, which confirmed no significant difference between the two rhizosheath communities (Permutation tests, R = 0.256, p = 0.089) but a highly significant difference between the rhizosheath and bulk soil communities (Permutation tests, R = 0.9, p = 0.0002) ( Figure 4 a,b). 2.3.2.
