Expression patterns of genes in the wing and eye-antennal clusters. In situ hybridizations of genes from (a-d) the wing and (f-i) eye-antennal disc clusters show the disc-specific patterns of expression. Confirming the mircoarray data, the signal intensities are higher in the wing discs in (a-d) (red frame) and the eye-antennal discs in (f-i) (green frame). Note the refined expression pattern in the wing disc for CG10962 in (c). In two cases, CG10962 (c) and CG9335 (g), signal could only be detected in the predicted disc. The arrowhead in (g) indicates the morphogenetic furrow. The number indicates the average fold induction in the 11 experiments. Arrestin2 (d) and CG11798 (f) were included in the clusters because their relative induction was >1.74 in more than five experiments. (e) CG6680 and (j) LD11162 failed the threshold criteria for the cluster depicted in Figure 4, but were part of a larger cluster with lower threshold settings. For both genes, the in situ patterns confirm the predicted expression. Discs are oriented anterior to the left, and dorsal uppermost.
