From: Spatially differentiated expression of quadruplicated green-sensitive RH2 opsin genes in zebrafish is determined by proximal regulatory regions and gene order to the locus control region

Translocation of the RH2-LCR revealed gene-order dependent competition for the RH2 regulation. a Translocation of the RH2-LCR. The RH2-LCR was removed from the original position and then re-inserted into the immediate downstream of RH2-3 in the RH2-PAC clones [18]. b Transverse sections of the adult transgenic zebrafish retinas of the PAC constructs where RH2-2 (left), RH2-3 (middle) and RH2-4 (right) are replaced with the GFP reporter respectively. The GFP signals appear as green. Note that in the left panel the green signal is saturated and only the autofluorescence from the retina is captured. The dorsal side is at the top, and the ventral side is at the bottom. Scale bars = 100 μm
