Relative expression levels of (A) Ta-IPS1.1, (B) Ta-PHT1.2 and (C) Ta-PHT1.6 in the shoots and roots of the wild type (WT) and the Ta-PHR1-A1 transgenic lines (Ov-1 and Ov-2). Seeds were germinated for 7 d, and then the germinated seeds with residual endosperm removed were transferred to nutrient solution containing 10 µm Pi (low P, LP) and 200 µm Pi (high P, LP), respectively. After the plants were grown in the low and high P nutrient solutions for 7 d, the shoots and roots were collected separately for gene expression analysis. Data were the mean ± s.e. of three replications.
