Visual representation of molecular interactions in the HSF flock. The molecular interactions for the genes with significantly different abundance between the resistant and susceptible lines in the HSF flock in response to a primary Haemonchus contortus infection for 3 days were displayed. The network was inferred using Ingenuity Pathway Analysis (IPA v01-13). Solid lines imply direct relationships between gene products while dotted lines imply indirect interactions. Red: the genes with a significantly higher abundance in the Resistant line than in the susceptible line. Green: the genes with a significantly lower abundance in the Resistant line than in the susceptible line. The degree of changes in gene abundance is represented by the intensity of the color.
