Fig. 4From: Potential molecular mechanisms of overgrazing-induced dwarfism in sheepgrass (Leymus chinensis) analyzed using proteomic dataModules that were extracted from the protein–protein interaction network. (a) Module 1, (b) Module 2, (c) Module 3, and (d) Module 4. The orange nodes represent the upregulated proteins in dwarf sheepgrass, the green nodes represent the downregulated proteins and the purple nodes represent the proteins predicted to interact with the differentially expressed proteinsBack to article page
