(A) Necrosis of old leaf blade tips in WT rice and the OsPHR2-overexpressing line (OsPHR2 OE) under high-P (HP) conditions. Bar: 1 cm.

(B and C) Shoot and root dry weights of WT and OsPHR2 OE rice. Data are means ± SD (n = 5).

(D and E) Total P concentrations in shoots and roots of WT and OsPHR2 OE rice. Data are means ± SD (n = 5).

Asterisks indicate significant differences among treatments determined by two-sided Student’s t-test (∗p < 0.05, ∗∗p < 0.01, and ∗∗∗p < 0.001). n.s., not significant. See also Supplemental Table 1.
