A, Tcas-ql VTGl (GT39); B, Tcas-ql ARSB (GT62); C, Tcas-ql MRP (GT63). All the Tribolium homologs were marked based on their relative gland expression levels (Figure 8). The solid red squares indicate each of the three quinone-less gene encoded proteins, the open red squares relatively high expression in gland samples, the solid black squares relatively high expression in the control sample, the open black squares the other Tribolium homologs, and an open black circle indicates a Tribolium homolog without OGS annotation. The numbers on the branching points are the statistical frequencies.
