Top changes in AS during development.

First column indicates the gene name at Wormbase. The second column shows the developmental stages showing the greatest differences in AS ratio for that gene. “RT-PCR Confirm” indicates those genes whose developmental alternative splicing was tested by RT-PCR, a “+” indicates that there is a correlation between ratios obtained with the microarray and rations obtained by RT-PCR, and “-“ indicates that no changes were detected by RT-PCR or that there is an anticorrelation (for details see Figure 3). Cassette exon a multiple of 3: the size of the cassette exon was measured to determine possible changes in the reading frame by its inclusion/skipping. The last two columns show the AS ratios (log scale) for alternative exon inclusion for N2 embryos vs. smg-1 mutant embryos or N2 embryos vs. smg-2 mutant embryos.
