(A) Pi concentration and (B) expression of OsPAP10c in leaves and roots of rice during a period of P starvation followed by resupply. Germinated seeds were grown in normal nutrient solution for 10 d and then transferred to solution without Pi for 10 d, followed by 2 d recovery (R) in normal solution. RNA was extracted for quantitative RT-PCR and OsPAP10c expression was normalized to that of OsACTIN. Data are means (±SEM) of three replicates. Significant differences compared with the control (0 d) were determined using Turkey’s test (***P<0.001).
