Principal coordinate analysis (PCoA) of the weighted UniFrac values among the field and ethylene addition incubation samples based on Bray-Curtis distances. a Bacterial community composition in the field by PCoA. The microbiota is clearly clustered into four groups that are marked with four coloured dotted ellipses. b The dominant OTU (relative abundance > 0.1%) scores of the bacterial community in the field according to the PCoA. c Bacterial community composition in the ET addition treatments by PCoA. d The dominant OTU (relative abundance > 0.1%) scores of the bacterial community in the ET addition treatments according to the PCoA. The arrows indicate the centroid of the constrained factor. Circle sizes represent the relative abundances of bacterial OTUs, and colours were assigned to different phyla. CRi, cassava rhizosphere soil in the interspecific experiment; BSi, bulk soil 20 cm away from the peanut and cassava plants; PRi, peanut rhizosphere soil in the interspecific experiment; PRm, peanut rhizosphere soil in the intraspecific experiment; BSm, bulk soil 20 cm away from peanut plants
