Data are indicated in number of clones. In the differential array screening (Figure 3), the positive clones that were found to be expressed preferentially in rods (Rod clones) or cones (Cone clones) were picked up. The nucleotide sequences of these clones were determined (Clones sequenced). Except for the clones of empty plasmids (Empty plasmids) and those found multiplicate (Multiplicate sequences), each clone was searched using the Blast N program (Query sequences). Among the genes found in the databases (Blast N hit), candidate genes specifically expressed in rods (Rod genes identified) and in cones (Cone genes identified) were identified. In the search, some of the clones were not found in the databases (No hit), and contiguous sequences were also found (Rod and Cone contiguous clones).
