As(V) Tolerance Phenotype Displayed by pht1;1-3.

(A) Above-ground phenotype of plants grown for 8 d on media with 30 μM As(V) (+AsV) or without (−AsV) at different Pi concentrations.

(B) Root hair elongation after 8 d of growth on media containing 30 μM Pi (−AsV) or 30 μM Pi plus 30 μM As(V) (+AsV).

(C) to (G) As(V) tolerance phenotype ([C] and [D]), root length (n ≥ 12; P < 0.01) (E), anthocyanin accumulation (n > 3; P < 0.01) (F), and total arsenic accumulation (n ≥ 3; P < 0.01) (G) of plants grown for 7 d on 30 μM Pi. Plants in (D) to (F) were grown for an additional 4 d on the same medium supplemented with 50 μM As(V) (+AsV) or without As(V) (−AsV). Plants in (C) and (G) were grown for an additional 12 d on the same medium supplemented with 50 μM As(V). Wild-type (white bars), pht1;1-3 (black bars), and heterozygous PHT1;1/pht1;1-3 (gray bars). Error bars represent sd. Bars in (C) and (D) = 0.5 cm.
