Phenotype of L.albABCG29 overexpression in rice under combined water and phosphorus-deficient soil conditions. a Phenotypes of rice plant rizhosheath under SD + P and SD-P in both WT and L.albABCG29 overexpression lines, b relative expression level, c total root length (cm), d root hair length (mm), e specific rhizosheath weight (mg cm^− 1 root length), f phosphorus uptake efficiency in the shoot (mg P plant^− 1), g phosphorus uptake efficiency in the root (mg P plant^− 1), h rhizosheath P concentration (mg P g^− 1, DW). Different letters show significant differences of mean ± SD of four replicates at P < 0.01 significance level. SD + P; soil drying with phosphorus, SD-P; soil drying without phosphorus, WW + P; well-watered with phosphorus, WW-P; well-watered without phosphorus; OE-L1, Overexpression Line 1; OE-L2, Overexpression Line 2
