Figure 2

Diversity metrics and taxonomical differences, between untreated substrates, in the bacterial microbiome of C. sativa’s rhizosphere and bulk soil. (A) Weighted UniFrac PCoA plot representative of substrate differences in the bulk soil and rhizosphere. Each point represents a sample and axis 1 and axis 2 represent the percentage of variance explained by each coordinate. (B) Shannon’s index of variations between the bulk soil and rhizosphere of Promix and Canna coco. Kruskal–Wallis pair-wise test was used to assess statistical significance between groups (*p<0.05, **p<0.01, ***p<0.001, ****p<0.0001). (C) Taxonomic bar plots of the relative frequency of bacteria at the phylum level between soil location and substrate. Low abundance taxa included: Chloroflexi, Myxococcota, Cyanobacteria, Bdellovibrionota, Gemmatimonadota, Armatimonadota, Firmicutes, Patescibacteria, Delsufobacterota, Hydrogenedentes, Dependentiae, Abditibacteriota, Sporochaetota, Fibrobacterota, Sumerlaeota, SAR324, FCPU426, Elusimicrobiota, WPS-2, RCP2-54 and MBNT15.
