Fig. 7. Schematic drawing of the effects of hunchback on the expression
of the target genes in Tribolium. (A) Wild type.
(B) Tc'hbpRNAi. Arrows indicate activation and bars
indicate repression. Unbroken lines indicate a possible direct interaction and
broken lines indicate a probable indirect effect. The red lines indicate the
actions of hunchback that appear to be conserved in all insects.
