FIGURE 4.
Primary root elongation of CK44 oxalate oxidase transgenic and wild-type lines after transplanting to mild (–0.3 MPa) or moderate (–0.8 MPa) water stress conditions. Data are means ± SE (n = 14–20). Asterisks denote significant differences between the transgenic and wild-type lines (t-test; ∗P < 0.05; ∗∗P < 0.01).
