Figure 3From: Key patterning genes contribute to leg elongation in water striders dpp expression and phenotypes generated by parental RNAi. (A-D) In situ hybridization revealing dpp mRNA expression in early embryos prior to limb bud formation (A), and embryos where the legs are extending (B-D). (E) Untreated embryo developing normally. (F) dpp RNAi resulted in halting embryonic development at an early stage. dpp: decapentaplegic; WT: wild type; T1, 2, 3: thoracic segments 1, 2, 3.Back to article page
