Hierarchical genetic networks for heat-responsive genes in the leaves (a) and hub genes (≥10 edges in Fig. S3a for the roots and ≥20 edges in Fig. S3b for the leaves) in the roots (b) and leaves (c) in response to drought. Gene to gene relationships were obtained by Popgenie v3.0 (http://popgenie.org/) using the exNet tool with a display threshold of 5 and an expand threshold of 7. Some hub genes are named in the networks and the abbreviations for these hub genes are as follows: ERF1 (Potri.010G072300), ETHYLENE RESPONSE FACTOR 1; HSPA2 (Potri.006G226800), HEAT SHOCK TRANSCRIPTION FACTOR A2; JAZ1 (Potri.001G166200), JASMONATE-ZIM-DOMAIN PROTEIN 1; STP13 (Potri.010G089800), SUGAR TRANSPORT PROTEIN 13; ZFHD1 (Potri.010G169400), ZINC FINGER HOMEODOMAIN 1; HSP70 (Potri.010G206600), HEAT SHOCK PROTEIN 70; STZ (Potri.002G119300), SALT TOLERANT ZINC FINGER; RD26 (Potri.011G123300), RESPONSIVE TO DESICCATION 26; RRTF1 (Potri.004G141200), REDOX RESPONSIVE TRANSCRIPTION FACTOR 1; ERF6 (Potri.001G154200), ETHYLENE RESPONSIVE ELEMENT BINDING FACTOR 6; ABR1 (Potri.002G065600), ABA REPRESSOR1; ABF2 (Potri.002G125400), ABA RESPONSIVE ELEMENTS-BINDING FACTOR 2; NST1 (Potri.011G153300), NAC SECONDARY WALL THICKENING PROMOTING FACTOR1; MYB108 (Potri.010G149900), MYB DOMAIN PROTEIN 108. Detailed information about the differentially expressed genes in each network is presented in Supplementary Table S5. GO terms enriched for each hub gene in the sub-network are also presented in Supplementary Table S6.
