Growth (a) and As accumulated concentration (b) of cells expressing PnPht1;1, PnPht1;2 and vector under the 80 μM AsV stress supplement with low (20 μM) or high (100 μM) Pi. Different lowercase letters represent the difference among cells under the same Pi concentration, P ≤ 0.05. * represents the difference of the same cells between 20 μM and 100 μM Pi, P ≤ 0.05. Error bars indicate mean values ± SD, (n = 4)
