Diversity and community structure of rhizosphere bacteria and fungi of A. lancea. Shannon index (A, E) shows α diversity, Chao1 index (B, F) shows richness, both at the OTU level. C and G: PCoA of rhizosphere bacteria (C) and Fungi (G) in A. lancea based on Bray-Curtis matrix at the OTU level (n = 3). D and H: Bar chart of rhizosphere bacteria (D) and fungi (H) in A. lancea rhizosphere at phylum level. (I, J) Cladogram showing the phylogenetic distribution of the bacterial (I, LDA score = 4) and fungal (J, LDA score = 2) lineages associated with the bottled soil and rhizosphere soil of A. lancea. Circles indicate phylogenetic level from phylum to genus. The diameter of each circle is proportional to the abundance of the group. Asterisks represent significant difference by Student’s t-test: *P < 0.05; **P < 0.01; ***P < 0.001; ND, no drought stress, 0% PEG6000; MD, mild drought stress, 10% PEG6000; SD, severe drought stress, 25% PEG6000; +I, with Geo-authentic soil microbe inoculation; +p, with A. lancea plantlet.
