Figure Caption

Fig. 3 Somite segmentation and PSM maturation are disrupted in SBU2 mutants. Whole mount RNA in situ hybridization of genes involved in somite segmentation process in wild-type and SBU2 mutants. All views are dorsal; anterior to the top. In wild-type embryos, periodic activation of notch signaling provides cycling gene expression of Notch pathway genes such as her1 and her7 (A–D and E–H). dld expression is weak and diffused in presomitic mesoderm as well as anteriormost somites (I–L). tbx24 normally expressed in intermediate and anterior PSM, is also reduced in SBU2embryos (M–P). Arrows denote stripes of her1, her7 or dld expression.
