Networks regulating CRC expression. (A) Localization and binding of CRC regulators based on Y1H and qRT-PCR results and [65]. Regulators were assigned to the conserved regions of proCRC (A–E) accordingly to the Y1H screen and in silico prediction analyses. Proteins without an arrow were not tested via qRT-PCR but interact with proteins identified in this study based on BioGRID searches [3]. Protein–protein interactions are symbolized by overlapping circles and proteins in blue were not present in the Y1H results, but link identified regulators to each other. Protein interactions are shown by overlapping circles, transcriptional activation and repression are symbolized by pointed or blunt-end arrows, respectively. (B) Contribution of flower-related processes to CRC expression. Colored circles indicate cofunctional networks with flowering induction in yellow, ab-/adaxial regulation in orange, carpel structures in dark blue, auxin response in green, meristem regulation in light blue, and flower development in purple. Protein interactions are shown by bars with two circles, transcriptional activation and repression are symbolized by pointed or blunt-end arrows, respectively.
