Gene expression pattern of OsMGT1 in response to Mg deficiency. Gene expression of all OsMGT_S family members in both shoots and roots (a). FC, fold change of induced expression. Effect of Mg sufficiency (+Mg), Mg deficiency (−Mg) and resupply (−+Mg) on the expression of OsMGT1 in shoot tissues (b), including leaf blade (LB), leaf sheath (LS) and node. I to III is from young to old. Time-dependent expression of OsMGT1 in shoots after exposure to −Mg (c). Effect of excessive Ca on the expression of OsMGT1 under −Mg condition (d). The expression level was determined by real-time RT-PCR. OsActin was used as an internal standard. Data are means ± SD (n = 3). The asterisk indicates significantly different (p ≤ 0.05 by Tukey’s test).
