Growth rates and As tolerance of cells expressing PnPht1;1 or PnPht1;2 supplement with 50 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 supplement with (+As) or without (−As) 80 μM AsV. b Growth rates of cells expressing PnPht1;1 supplement with (+As) or without (−As) 80 μM AsV. c Growth rates of cells expressing PnPht1;2 supplement with (+As) or without (−As) 80 μM AsV. d As tolerance (%) indicated by the proportional growth rate of the each transgenic yeast line in the presence of AsV compared with control growth. Different lowercase letters represent the difference of As tolerance among cells, P ≤ 0.05. Values are the mean ± SD (n = 4)
