Bacillus inoculation increases rice rhizosheath formation in association with P acquisition under SD−P conditions. A, Phenotypic characteristics of WT and TP-LaPAP12 rice. B, Total root length (cm). C, Specific rhizosheath weight (mg soil cm⁻¹ root). D, Root APase activity (U g⁻¹ FW). E, Rhizosheath APase activity (U g⁻¹ FW). F, Root P content (mg g⁻¹ DW). G, Rhizosheath P concentration (mg g⁻¹ DW). H, Leaf P content (mg g⁻¹ DW). I, Stem P content (mg g⁻¹ DW). Data are mean ± standard error (n = 20). Uninoculated, soil without inoculated B. megaterium; inoculated, soil inoculated with B. megaterium.
