Temporal and spatial expression of methyltransferases. WISH signals for dnmt1 (A, B), dnm3aa (C-F), dnmt3ab (G, H) and dnmt3bb.1 (I, J) at different ages (0–9 dph) are shown. The ‘indicates the ventral orientation. Structures with an abundant signal are indicated with arrows: (an) anus; (ba) branchial arches; (br) brain; (cmz) ciliary marginal zone; (dm) dorsal midbrain; (ey) eye; (fb) forebrain; (fmb) forebrain-midbrain boundary; (gcl) ganglion cell layer; (hb) hindbrain; (inl) inner nuclear layer; (ipl) inner plexiform layer; (in) intestine; (mb) midbrain; (mhb) midbrain-hindbrain boundary; (mo) mouth; (pd) pronephric duct; (pf) pectoral fin buds; (ph) pharynx; (sc) spinal cord; (so) somite; (te) tectum. Scale bars are indicated (100 and 200 μm)
