Expression of candidate genes during jaw outgrowth in Dermogenys pusilla. (A) Cartoon of tissue sampling for the expression analyses. Upper and lower jaws were excised at the level indicated by the orange and blue colouring respectively, from stages indicated. (B-E) Expression of candidate genes (B) sox9b, (C) runx2, (D) bmp2 and (E) bmp4. Relative expression values are scaled so that expression in the lower jaw in embryos = 1. Standard error is indicated. Two-way ANOVAs indicated statistically significant differences in expression for sox9b (P < 0.001), runx2 (P < 0.01) and bmp2 (P < 0.05) but not bmp4 (P > 0.1) (see Table 1). RQ = relative quantitation.
