Fig. 5 — The putative gene regulatory networks (GRNs) that regulate the production of chagamous (CH) and cleistogamous (CL) flowering in Pseudostellaria heterophylla. Genes represented by blocks. Lines with an arrow represent promotion, and those with a perpendicular bar represent repression. a GRNs in CH flower production. b GRNs in CL flower production. Gene expression variation represented by different colour in CL flowering GRNs: gene expression level not to change is shown in white; gene expression level up-regulated is shown in red; gene expression level down-regulated is shown in green. FKF1down-regulated due to the change of Circadian Clock, FT down-regulated due to the poor light quality, the floral identity gene AP1up-regulated due to STM promotion. AP3 and PI down-regulated due to down-regulated upstream genes
