Effects of different P sources on seed yield, P concentration, P accumulation, phytase activity and phytic acid content of WT and transgenic lines grown in P deficient soil.

<p>Values represent means ± SD of four replicates. A significant difference (*, ** at <i>P</i><0.05 and <i>P<</i>0.01, respectively) between the WT and transgenic lines in the same P treatment was calculated by LSD test. HP treatment: 200 mg P₂O₅ kg^–1 soil with KH₂PO₄; LP treatment: 20 mg P₂O₅ kg^–1 soil with KH₂PO₄; Phy-P treatment: 200 mg P₂O₅ kg^–1 soil with phytate. n.d., means not detectable.
