Epistatic Networks Controlling GLS Traits.

The genetic network from Figure 1 is used to represent the significant epistatic interactions for the four major GLS traits. Only connections that show significant epistasis are maintained, while nonsignificant connections are dropped from the network. A solid line shows that only the TF x TF interaction term was significant in the ANOVA model. A dashed line shows epistatic interactions where there was a significant tissue x TF x TF interaction. A dotted line shows epistatic interactions where there was a significant environment x TF x TF interaction. A line of arrows shows that the interaction was conditional on both tissue and environment. The color of the node indicates which main effect terms are significant for the individual TFs: Sky blue indicates only a TF main effect, orange indicates only a tissue x TF interaction, purple indicates both TF and tissue x TF, yellow indicates both TF and treatment x TF, and red indicates that all three terms are significant. Gray indicates that no terms for the individual TF were significant.
