TABLE 2.

Community parameters obtained from Illumina sequencing data of the V6-V8 region of 16S rRNA genes, from rhizospheric samples associated with E. platyacanthus (Ep) and N. polylopha (Np), cultivated (C) and wild (W). Presented parameters and their standard deviation values are treatment estimators of species richness (Observed ASV, Chao 1), Shannon’s (H’) and Simpson’s (D) diversity indices, and Pielou’s (J) evenness index. Calculations were done after rarefying the respective classified reads (see Supplementary Table S1), to 5,213 sequence reads, corresponding to the smallest number of classified reads in sample NpW-2.
