Impact of drought stress on transcription of sulfate transporters leaves and roots of maize. Transcript steady state levels of three genes encoding for maize sulfate transporters SULTR1;1 (a, b), SULTR1,2 (c, d) and SULTR4;1 (e, f) in leaves (a, c, e) and roots (b, d, f) of control (black) and drought-stressed plants (white). Data are means ± SD of three individual replicates. Asterisks indicates statistical differences as determined by the unpaired t-test (*, 0.05 ≥ p > 0.01; **, 0.01 ≥ p > 0.001; ***, p ≤ 0.001)
