Fig. 5. — Nv-nos function in embryonic patterning. (A) Wild-type Nv-gt mRNA expression (red) with Nv-Hb protein (green). (B) Wild-type expression of Nv-kr mRNA (red) and Nv-Hb protein (green). (C) Wild-type first instar larval cuticle. Green arrow indicates spiracle on second thoracic segment, red arrows indicate the first three abdominal segment spiracles (also in F and I). (D) Nv-nos pRNAi embryo showing posterior shift of the posterior Nv-gt domain. (E) Nv-nos pRNAi embryo showing expansion of Nv-kr domain posteriorly and loss of the posterior Nv-Hb domain at the posterior. (F) A severely affected Nv-nos pRNAi embryo. (G) Nv-vasa pRNAi results in loss of the posterior Nv-gt and Nv-Hb domains. (H) Nv-kr expression expands to the posterior pole in Nv-vasa pRNAi. (I) The majority of abdominal segments are lost in Nv-vasa pRNAi. (J) Nv-smaug causes a compression of the Nv-gt and Nv-Hb anterior domains, while the Nv-kr (K) domain is shifted significantly towards the anterior.
