Figure 4.

Protein expression patterns in the total plasma membranes of rice seedling roots exposed to cadmium or cadmium and SNAP. The total plasma membrane proteins from third-leaf-stage rice seedling roots were treated with 10 μM cadmium with or without 30 μM SNAP for 12 h and 1 day, and the differential expression protein were identified by the iTRAQ method. The number of up-regulated and down-regulated proteins were listed (A), and hierarchical clustering of cadmium- and SNAP-responsive proteins were also presented (B). The colors correspond to the log-transformed values of the protein change-fold ratios, as depicted in the bottom-right bar.
