Extended Data Figure 3: Segmental patterns of GFP reporter expression in transgenic zebrafish lines.
From: A Hox regulatory network of hindbrain segmentation is conserved to the base of vertebrates

Lateral (top) and dorsal (middle) views of 30Â hpf transgenic (F1) zebrafish embryos show combined brightfield illumination and segmental GFP reporter expression in the hindbrain mediated by five different gnathostome enhancer elements. The corresponding transient transgenic GFP expression patterns mediated by these elements are shown in Fig. 1b and Extended Data Fig. 2. When available, GFP lines were crossed with the endogenous r3r5-mCherry reporter line as a reference (bottom). The otic vesicle is circled. m, mouse; zf, zebrafish.
