Supplementary Figure S1: Analysis of network topology for various soft-thresholding powers.

Supplementary Figure S2: Clustering of module eigenvectors (ME) of the co-expression networks comprising nine and eight modules for HKI1532 and PC3 respectively.

Figure S3: Validation of selected DEGs from GeneChip by qRT-PCR tested in HKI1532 (Tolerant) and PC3 (Sensitive) genotypes. ZmNAC18, a previously published drought-responsive gene, is used as an external control. Genechip values are given on the label (orange).

Supplementary Figure S4: Scatter plot between the number of edges (log(k)) and the probability of a node having k edges (P(k)).

Supplementary Table S1: Selected DEGs from GeneChip for validation by qRT-PCR.

Supplementary Table S2: Drought-responsive DEGs exclusively up-regulated in HKI1532.

Supplementary Table S3: Transcription factors unique to HKI1532 and their expression values under water stress.

Supplementary Table S4: A set of 174 selected drought-responsive genes from HKI1532 and their co-expression network groups.
