Growth rates of cells expressing PnPht1;1 or PnPht1;2 supplement with 20 μM Pi. Measurements of OD600 during logarithmic growth were used to generate exponential trend lines (y(t) = a × ekt), where k is the growth rate coefficient. a Growth rates of cells expressing vector. b Growth rates of cells expressing PnPht1;1.c Growth rates of cells expressing PnPht1;2. d Growth rate coefficient. Different lowercase letters represent the difference of growth rate coefficient among cells, P ≤ 0.05. Error bars indicate mean values ± SD, (n = 4)
