Tc-cncRNAiresults in deletion of the Labrum. Scanning electron micrographs (SEMs) of wild-type and Tc-cncRNA embryos shows the deletion of the Labrum in Tc-cncRNAi embryos. All views are ventral with anterior to the left. (A) SEM of a wild-type embryo at fully extended germ band stage. The labral buds are clearly visible at the anterior of the embryo (arrow). The mandible is indicated (arrowhead). (B) SEM of Tc-cncRNAi embryo at germ band extending stage. The labral buds are missing (arrow). The mandible is transformed into maxillary identity (arrowhead).
