Figure 2. Root architecture of seedlings.

Seedlings were cultivated on media with 100 µM (black bars) or 3 µM (gray bars) Pi for seven days. (A) Length of primary root, (B) number of lateral roots. Data are presented as means ± SD (n = 3 with seven plants each) and were compared between high/low Pi by the Student’s t test; * P ≤ 0.05.
