Figure 4

The starch sub-network of 16 starch genes and their first step neighbours (Q < 0.05). (a) The graphical display of the starch sub-network. A pink rectangle represents a TF gene; an orange diamond represents a clock gene; a green circle represents a starch gene; a black solid line represents an association with positive correlation; and a blue broken line represents an association with negative correlation. (b) The metabolic display of the starch sub-network. A pink oval represents a TF gene; A red oval represents a TF gene predicted to have physical binding sites in target genes according to the comparative TF family analysis; an orange diamond represents a clock gene; a green rectangle represents a starch gene; a blue rectangle represents a metabolite; a black line represents an association with positive correlation; a red line represents an association with negative correlation; and a blue line represents a reaction in starch metabolism.
