Expression of Tribolium, Glomeris and Euperipatoides SoxE. In all panels, anterior is to the left. All panels, ventral views, except for panels k, m, p and q (lateral views). a-d Expression of Tribolium SoxE. e-h Expression of Glomeris SoxE1. i-m Expression of Glomeris SoxE2. n-s Expression of Euperipatoides SoxE. Panels n´ to p´ show DAPI stained embryos as shown in n to p. Developmental stages are indicated for Tribolium (after Strobl and Stelzer [27]), Glomeris (after Janssen et al. [26]), and Euperipatoides (after Janssen and Budd [23] ). Arrows in panels b-d point to posterior expression, possibly associate with the formation of the Malpighian tubules. Asterisks in panels b-d mark the primordia of the Malpighian tubules. The inlay in panel i shows expression in the anal valves. Arrow in panel r point to expression between the jaw and the slime papilla. Abbreviations as in Fig. 2, and (lr), primordium of the labrum; a, anus; an, antenna; av, anal valves; L5 and L6, fifth and sixth trunk segment; mx, maxilla; T1, first trunk segment
