Sub Network Enrichment Analysis (SNEA) connecting significant proteins and regulators or targets from proteomic studies. a / Comparison of 2^ry vs 1^ry lines; b / Comparison of 3^ry vs 2^ry lines somatic embryogenesis in Douglas-fir. The Douglas-fir significant proteins (ratio 1.5, p < 0.05) are named by their Arabidopsis homologues. The correspondences between Douglas-fir and Arabidopsis protein names are given in Additional file 1. Red color: sur-expression of this protein in 2^ry lines in a and 3^ry lines in b; blue color: sur-expression of this protein in 1^ry lines in a, 2^ry line in b; grey color: protein significant in the proteomic comparison
