Gene expression of Cluster-I, -II, and -IV markers. In all panels, anterior is to the left, except panels D, H, L, P, T and X where anterior is up. Panels A, I, K, M and R represent lateral views. Panels B, C, E, F, G, J, N, Q, S, V and W represent ventral views. Panels D, H, L, P, T and X represent anterior views. Schematic drawings in the right column summarize the main gene expression characteristic for a given cell cluster (blue tissue). Arrows and arrowheads in schematic drawings point to comparable expression as marked by the same symbols in the original photographs. Abbreviations of gene names is indicated in the upper left corner. Developmental stages are indicated in the bottom right corner. For further information, see Supplementary Figs. 2–4 and 9–11, and Supplementary File 6. Abbreviations used in schematic drawings: aSP, anterior pair of spinnerets; bl, book lung; ch, chelicera; CNS, central nervous system; h, heart; L1-L4, first to fourth leg; lr, labrum; m, mouth; pp, pedipalp; pSP, posterior pair of spinnerets; tr, trachea; vs, ventral sulcus
