Gene expression patterns in adult gonads at 8 mpf. Wild-type ovaries (A, C, E, G, I, K, M, O, Q, and S); amh-26 mutant ovaries (A’, C’, E’, G’, I’, K’, M’, O’, Q’, and S’); wild-type testis (B, D, F, H, J, L, N, P, R, and T); amh mutant testis (B’, D’, F’, H’, J’, L’, N’, P’, R’, and T’). In situ hybridization for amh (A, A’, B, and B’), bmp15 (C, C’, D, and D’), gdf9 (E, E’, F, and F’), gsdf (G, G’, H, and H’), cyp19a1a (I, I’, J, and J’), gata4 (K, K’, L, and L’), bmpr2a (M, M’, N, and N’), bmpr2b (O, O’, P, and P’), nr5a1a (Q, Q’, R, and R’), and vasa (S, S’, T, and T’). Small boxed regions in low magnification views are shown in larger boxed regions at higher magnification for B, B’, I, I’ K, K’, M. M’, O, O’, Q, Q’. Bar for main panels represents 100 mm; bar for higher magnification in boxed regions represent 25 mm. I, II, III, IV, ovarian follicle stages 1–4.
