Transcriptomic Analysis of Cadmium Stress Response in the Heavy Metal Hyperaccumulator Sedum alfredii Hance
Figure 5
Comparison of gene expression in S. alfredii Hance hyper-accumulation ecotype (HE) and non-hyperaccumulation ecotype (NHE).
(A) Transcriptional responses of two ecotypes to Cd exposure. Fold change of expression is the relative gene expression level in Cd treatment divided by the value in the control. (B) Relative gene expression levels of two ecotypes under normal growth condition. The relative gene expression is the expression level normalized to a constitutively expressed gene Actin. P-type metal ATPase HMA4: Sa_Contig11685; Zinc transporter ZIP1: Sa_Contig10290; Metal tolerance protein MTP3: Sa_Contig47062. The contig numbers for other genes are listed in Table 1. P values are indicated as follows: *P<0.05; **P<0.01; ***P<0.001. Bars depict SE (n = 3).
