Expression of MADS-box genes and VprAP3/VprPI co-expression networks in V. prionantha. (A) Heatmap displaying the expression profile of the identified MADS-box genes at three developmental stages. Red represents high gene expression in CL, and blue represents low expression in CL. The fold change of differential expression (CL/CH) during the three stages (S1, S3, and S5) is labeled on the top. (B) VprAP3 and VprPI co-expression network analysis. All co-expressed genes (Mutual-Rank < 10) with VprAP3 and VprPI are indicated by yellow circles, and VprAP3 and VprPI are highlighted by blue diamonds. (C) Significantly enriched GO terms of the 37 co-expressed genes of VprAP3 and VprPI
