Functional interactions and abundance profiles of proteins involved in female reproductive organ, embryo and seed development. a Protein-protein functional interaction network generated using STRING. b Hierarchical clustering heatmap showing expression profiles for the selected proteins. Thickness of the line in interaction maps indicate the degree of confidence for prediction of the interaction. Dotted boxes with labels highlight the subset of proteins involved in respective processes. Z-score or scaled expression value of each protein is plotted in red-green color scale. The red color of the tile indicates higher level and green indicates lower level. FE (Red), Early-staged Female; FM (Green), Middle-staged Female; ME (Blue), Early-staged Male; MM (Turquoise), Middle-staged Male
