Figure 6.

Schematic diagram of SRP proteins involved in natural rubber biosynthesis (NRB). A schematic diagram of enzyme localization and the regulation of ethylene-induced biochemical pathways on the protein level in SRPs are both highlighted. In this schematic diagram, the identified proteins involved in NRB from SRPs are marked with different colors (green, unchanged protein; red, changed protein), and the changed patterns determined by 2-D DIGE (D-) and iTRAQ (I-) for these DAPs are provided in the parentheses. The up arrow stands for upregulation, the down arrow stands for downregulation, and minus sign the protein is not significantly changed after ethylene application.
