(a) Significantly enriched biological processes for T. chinensis genes up-regulated under water deficit treatment (TCWD) relative to its well-watered control. Significant enrichment networks were performed using DEG in the iGraph R package in the ShinyGO web server. Networks consist of nodes and lines connecting the nodes. Nodes are circles, which denote the different biological process categories. The color of the circle denotes the direction of regulation of the genes belonging to each enriched biological process in the network. Lines denote the interactions, which are the genes that are common between any two biological processes. Darker green color in the circles indicates greater up-regulation of genes. (b) Significantly enriched biological processes for T. ramosissima genes up-regulated under water deficit treatment (TRWD) relative to its well-watered control. Significant enrichment networks were performed using DEG in the iGraph R package in the ShinyGO web server. Network consists of nodes and lines connecting the nodes. Nodes are circles, which denote the different biological process categories. The color of the circle denotes the direction of regulation of the genes belonging to each enriched biological process in the network. Lines denote the interactions, which are the genes that are common between any two biological processes. Green color in the circles indicates greater up-regulation of genes. Enriched GO categories down-regulated in TRWD were negative regulation functional categories (cellular processes, gene expression, signaling and RNA biosynthesis) and functional categories related to the positive regulation of chromatin and histone modifications (Table S6d).
