From: Transcriptional profile of maize roots under acid soil growth
Effect of acid soil saturated with Al3+ on maize root growth. Plants were grown in acid (pH 4.2) or control (pH 5.5) soil for one or three days. The growth is relative to the control soil (pH 5.5). Vertical error bars represent mean ± SE (n = 20). The difference between the two lines in each treatment was significant at p < 0.05.
