Drought specific PPI sub-network for the key genes involved in the pathway cross-talk network. Blue elliptic nodes represent drought specific pathway genes, MDSGs, while the rose elliptic nodes denote the rest of DRGs, non-MDSGs. The ellipse shape of the nodes shows that all the genes are involved in the drought associated cross-interaction network. Each octagonal node indicate one of the 14 set of pathway DSRhub gene and the color of the octagonal nodes indicate the size of interacting geneset, such that the brighter the color, the greater the number of interacting set of genes. For 14 nodes each represented by DSRhub genes, a total of 266 nodes were denoted by interacting genes that are involved in the pathway defined cross-talking relations.
