Supplemental Figure 2. RT-qPCR validation of genes identified as up-regulated in P1-rr by RNA-Seq. Genes (18) that showed up-regulation in P1-rr (pericarps and silks) RNA-Seq experiments were chosen for validation. Left, relative expression of genes to actin in P1-rr and P1-ww pericarps at 14 and 25 DAP. Right, RT-qPCR expression of the same genes relative to actin in P1-rr and P1-ww silks. The results obtained by RT-qPCR correlate to the expression values obtained by RNA-Seq in 16/18 for pericarps and 12/18 for silks. P-values for the difference in gene expression for biological triplicates were included for some of the genes described in more detail in the text. Single or double asterisks indicate significant (P < 0.05) or very significant (P < 0.01) differences between P1-rr and P1-ww.

Box plot of gene expression distribution from RNA-Seq conducted from root, shoot, leaf, silk and pericarp tissues. The x-axis corresponds to the tissue and y-axis corresponds to the log10 transformed FPKM values. The width of the boxes is proportional to the square-roots of the number of gene expressed per sample. Expression of P1 (blue “!” signs), A1 (orange “+” signs) and two housekeeping genes, Ubiquitin (red “-” signs) and Actin1 (green “*” signs), are shown. B. Pearson correlation coefficient-based heat-map matrix of all the RNA-Seq expression analyses. The results of the hierarchical clustering are illustrated as a dendrogram, according to expression pattern similarities.

Supplemental Figure 5. Box plots corresponding to expression distribution within the K1 - K8 clusters. Box plots depict the activation and repression patterns corresponding to clusters K1 to K8 for silks, pericarps 14 DAP and pericarps 25 DAP. Relative expression for each cluster was obtained by calculating the log2 of the ratio between P1-rr and P1-ww FPKM values.

B. Diagrams of the constructs used for transient expression experiments in maize protoplasts for C2 (pC2:Luc), WHP1 (pWHP:Luc), A1 (pA1:Luc) and A1* (pA1*:Luc). C. Transient expression assays using maize protoplasts transformed with pA1:Luc, pA1*:Luc, pWHP:Luc and pC2:Luc. For each experiment, protoplasts were also transformed with p35S:P1 or p35S:C1 + p35S::R constructs in addition to p35S:Renilla. Each treatment was done in triplicate, and the data were normalized for Renilla activity as described (Grotewold et al., 2000). The fold activation was calculated as the ratio between each particular treatment and the treatment with the promoter constructs without activator. The average values are shown and the error bars indicate the standard deviation of the samples. D. Electrophorectic mobility shift assays (EMSA) showing binding of the MYB domain of P1 (+) expressed and affinity-purified from bacteria as a poly-histidine fusion (NHis6-P1MYB, (Xie et al., 2010)) to the indicated binding sites on the WHP1 5’ regulatory region. Lanes indicated by “-“ correspond to DNA-binding reactions performed in the absence of NHis6-P1MYB.

Supplemental Figure 10. Motif enrichment in genome-wide location analysis peaks in P1-controlled genes. A. Top motif identified as enriched by MEME in peaks from genes up- (UP) or down- (DOWN) regulated by P1. B. Frequency distribution of sequences fitting the P1-binding consensus CC(T/A)ACC in experimental peaks from genes up- (UP) or down- (DOWN) regulated by P1. The frequency bars show the number of peaks fitting the consensus in 1,000 permutations of randomly chosen sequences; number and length corresponding to those in each of the experimental peak sets (227 for UP and 471 for DOWN). The P-value reflects the statistical likelihood that the observed number is different than the expected number.

Supplementary Figure 11. Venn-diagrams summarizing the overlap between the genes expressed in pericarp and silks as detected with RNA-Seq and microarrays. Overlap between RNA-Seq and microarray (Sekhon et al., 2011) in silks and pericarps tissues. A. In pericarps, 2,314 genes detected by microarrays were not present in the RNA-Seq experiments, and 7,642 genes were detected by RNA-Seq, but not by microarrays. B. In silks, 3,287 genes detected in microarray experiments failed to be detected by RNA-Seq, and 5,988 genes were detected only by RNA-Seq.

Supplemental Figure 12. Phylogenetic analyses of UDP-sugar:glycosyltransferases from higher plants. The tree was constructed using MEGA 4.0 Software with the Neighbor-Joining method based on ClustalW multiple alignments (Tamura et al. 2007). The numbers indicate bootstrap values (10000 replicates). Bar = 0.1 amino acid substitutions per site.
