Network of DEPs identified in germinating B. napus seeds with high and low oil content. The associations between these 165 DEPs were analyzed by STRING 10.0, and then the protein association network was optimized with Cytoscape 3.2. A total 87 nodes and 400 lines are obvious in the network. The nodes represent DEPs and the lines represent protein-protein associations. The associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function and this does not necessarily mean they are physically binding each other. The thickness of line indicates the strength of data support for the associations among DEPs. These nodes were grouped into 10 subgroups according to their function. a, amino acid metabolism; b, cell growth/division; c, sugar metabolism; d, defense/disease; e, energy metabolism; f, protein metabolism; g, unknown function; h, seed maturation; i, storage proteins
