Effects of rdRNAi against Gb'Dll and Gb'dac on expression patterns of tarsal patterning genes, with schematic illustrations.

(a–d) Expression patterns of Gb'Egfr in regenerating tarsi at 5 dpa for DsRed2 rdRNAi (a), Gb'Dll rdRNAi (20 μM) (b), Gb'Dll rdRNAi (0.2 μM) (c) and Gb'dac rdRNAi (d) nymphs. (e–h) Expression patterns of Gb'al in regenerating tarsi at 5 dpa for DsRed2 rdRNAi (e), Gb'Dll rdRNAi (20 μM) (f), Gb'Dll rdRNAi (0.2 μM) (g) and Gb'dac rdRNAi (h) nymphs. (i–l) Expression patterns of Gb'BarH in regenerating tarsi at 5 dpa for DsRed2 rdRNAi (i), Gb'Dll rdRNAi (20 μM) (j), Gb'Dll rdRNAi (0.2 μM) (k) and Gb'dac rdRNAi (l) nymphs. (m–p) Expression patterns of Gb'bab in regenerating tarsi at 5 dpa for DsRed2 rdRNAi (m), Gb'Dll rdRNAi (20 μM) (n), Gb'Dll rdRNAi (0.2 μM) (o) and Gb'dac rdRNAi (p) nymphs. (q) Schematic illustration of a plausible relationship between expression patterns of the tarsal patterning genes in a wild-type presumptive tarsus at 5 dpa and in tarsal segments 1–3. See details in the text. (r) Schematic illustration of a plausible relationship between tarsal segment-1-like structure and expression patterns of the tarsal patterning genes in a presumptive tarsus at 5 dpa observed in a nymph treated with rdRNAi against Gb'Dll (0.2 μM). See details in the text. Scale bar = 100 μm.
