Module for ABA signaling pathway in osmotic stress responses of Z. xanthoxylum roots. a Functional network based on known Arabidopsis ABA-dependent signaling components, cross-referenced against the complete DEG functional network. Node colors represent different classes of signaling components: orange, ABA biosynthesis; red, receptors; yellow-green, PP2Cs, green, kinases; dark magenta, transporters; magenta, transcription factors; and blue, UPS enzymes. Border colors of nodes represent expression as log2 fold-change. Magenta, increased expression; the deeper the color, the higher the expression. Green, decreased expression; the deeper the color, the lower the expression. Edge (line) colors, interactions of proteins in the core ABA signaling pathway (red), kinases (green), UPS enzymes (blue), transcription factors (magenta), and proteins except in the same class (cyan). Thickness of edges, normalized link closeness; the thicker the edge, the closer the link. b ABA signaling and biosynthetic pathway components. Shading, colors represent different classes of signaling components: orange, ABA biosynthesis; red, receptors; yellow-green, PP2Cs, green, kinases; dark magenta, transporters; magenta, transcription factors; and blue, UPS enzymes
