GRN Predictions Show Enrichment of Documented Transcriptional Regulation Interactions from Arabidopsis.

(A) Permutation analysis showing the number of random TF-target interactions supported by at least one of the 45 GRNs (histogram) compared with the actual transcriptional regulation (transferred from Arabidopsis) with GRN support (red dashed line).

(B) Abscisic acid pathway transferred from Arabidopsis showed support for 12 of 20 edges.

(C) Six of 11 HY5 targets transferred from Arabidopsis showed support in at least one GRN. The letters along the edges of the networks in (B) and (C) indicate significant support from a specific GRN, as indicated in the key.
