Bacteria diversity and community of aerial root mucilage (mucilage) and underground rhizosphere soil (rhizosphere). a Unconstrained PCoA with Bray–Curtis distance showing that the bacteria of mucilage separate from those of rhizosphere and soil in the first axis (P < 0.001, permutational multivariate analysis of variance (PERMANOVA) by Adonis). b Shannon index of the bacteria of aerial root mucilage, underground rhizosphere soil, and the corresponding bulk soils (P < 0.01, two-sided Wilcoxon test). c Top three Genus-level distribution of bacterial communities in mucilage and rhizosphere soil. Burkholderia-Caballeronia-Paraburkholderia, Herbaspirillum, and Novosphingobium are higher relative abundance in mucilage (59.09%, 10.43%, and 5.36%, respectively) than in underground rhizosphere soil (0.14%, 0.22%, and 0.64%, respectively). The numbers of replicated samples in this figure are as follows: mucilage (n = 5), rhizosphere soil (n = 5), and soil (n = 5)
