The effect of Al3+ exposure or P deficiency on HvALMT1 expression in shoots and roots of barley. HvALMT1 expression was determined using qRTPCR in plants of an Al3+-sensitive (Golden Promise) or Al3+-resistant (Dayton) cultivar grown for 4 d in hydroponics containing no added Al3+ (minus Al) or 2.5 μM Al3+ (plus Al); or for the P experiment in 13-day-old plants after 6 d of growth in hydroponics containing no added P (minus P) or 100 μM P (plus P). The expression level is shown relative to the internal reference gene GAPDH (mean ± SEM; n=3 or 4). For each panel, columns designated with different letters are significantly different (P <0.05; ns=not significant).
