Early expression of Parasteatoda spalt1. A–D show the germ disc. The asterisks mark the centre of this disc, the later posterior pole of the embryo (cf. E). In all panels, the arrows point to the transforming central domain if expression and the arrowheads point to the more distal (later anterior) domain of expression. E–H show the early germ band, ventral views (except for H, lateral view). In E–I, anterior is to the left. In J, anterior is up, lateral view. A´–H´ represent SYBR Green-stained embryos as shown in A–H. Abbreviations as in Fig. 2
