Fig. 2

Expression of Tribolium and Euperipatoides SoxNeuro (SoxN). In all panels, anterior is to the left. All panels, ventral views, except for panels h and j (lateral views). a-e Expression of Tribolium SoxN. f-k Expression of Euperipatoides SoxN. Panels to show DAPI stained embryos as shown in f to h. Developmental stages are indicated for Tribolium (after Strobl and Stelzer [27]) and Euperipatoides (after Janssen and Budd [23]). Asterisk (*) in panel a marks ventral tissue that expresses SoxN only weakly. Arrows in panels c-e point to expression in the VNS. The arrows in panels d and e point to expression in the brain. Abbreviations: bp, blastopore; fap, frontal appendage; j, jaw; L1, first walking limb; lr, labrum; m, mouth; md, mandible; hl, head lobe; ser, serosa; saz, segment addition zone; sp, slime papilla
