Figure 3. Complex splicing patterns are largely limited to neural tissues.
a, A small minority of genes (47, 0.2%) encode the majority of transcripts. b, In situ RNA staining of constitutive exons of four genes with highly complex splicing patterns in the embryo. Syncrip (Syp), Cap, Retinal degeneration A (rdgA) and GluClalpha show specific late embryonic neural expression in the ventral midline neurons; dorsal/lateral and ventral sensory complexes; Bolwig's organ or larval eye; and central nervous system respectively.
