Expression of WntA genes. Expression of of WntA in Parasteatoda (A–D), Pholcus (E–H), Acanthoscurria (I–M) and Phalangium (N–S). In all panels, anterior is to the left. Panels A, B, E, F, O, and P show lateral views. Panels C, D, G, I–N, R, and S represent ventral views. Panels H and Q show posterior views. Panels A´ and N´ represent SYBR-green staining of the embryos shown in corresponding panels. Developmental stages are indicated. Arrowheads in panels F and H point to expression dorsal to the basis of the opisthosomal appendages. In all panels, arrows point to expression in the ventral nervous system. Expression patterns are summarized in panel T; anterior is up. Abbreviations as in Fig. 4
