图7 甘蔗ScMT2-1-5基因在不同重金属胁迫下的表达模式 A、C和E分别为ScMT2-1-5在CdCl2、ZnSO4和CuCl2处理下的表达模式。B、D和F分别为ScMT2-1-5在CdCl2、ZnSO4和CuCl2处理下和相应对照中相对表达量的比值。误差线为每组处理的标准误(n = 3)。图柱上不同的小写字母表示5%水平下差异的显著性。

Fig. 7 Expression patterns of ScMT2-1-5 in sugarcane under different heavy metal stresses A, C, and E represent the expression patterns of ScMT2-1-5 in response to CdCl2, ZnSO4, and CuCl2, respectively. B, D, and F represent the ratio of ScMT2-1-5 expression level between treatment (CdCl2, ZnSO4, and CuCl2, respectively) and their control groups. The error bars represent the standard errors of each treating group (n = 3). Bars superscripted by different letters are significantly different at the 5% probability level.
