Fig. 7From: Knockdown of five trehalase genes using RNA interference regulates the gene expression of the chitin biosynthesis pathway in Tribolium castaneum Effects on other genes in the chitin biosynthesis pathway after specific RNAi in last-instar larvae at 24 and 36 h. The mRNA levels of glucose phosphate isomerase (GPI), fructose phosphate transaminase (GFAT) and phosphofructokinase (PFK) relative to the Tcβ-actin mRNA level were measured via qRT-PCRBack to article page
