Phenotypic characterization of L.albABCG29 in white lupin grown under phosphorus sufficient (CK) and low phosphorus (LP) conditions. a Relative expression of L.albABCG29 in transgenic white lupin hairy roots b schematic representation of the GUS vectors for transient expression (top panel). The native promoter of L.albABCG29 drives GUS expression in transgenic L. albus roots under CK and LP conditions (lower panel), c phosphorus concentration (mg P g^− 1, DW) in different parts of white lupin root, d total root length (cm), e total plant biomass (g plant^− 1) of transgenic (OE-L1/L2) and wild type (WT) white lupin. Different letters show significant differences of mean ± SD of four replicates at P < 0.01 significance level. OE-L1, Overexpression Line 1; OE-L2, Overexpression Line 2
