her1 and dlc transcripts accumulate post-transcriptionally in pnrc2oz22mutants. Exonic in situ probes reveal that segmentation clock-associated her1 and dlc transcripts are misexpressed in the expected one-quarter of embryos in a pnrc2oz22 intercross, n=13/57 (X2=0.1, p=0.7) and n=8/30 (X2=0.04, p=0.83), respectively (A, B and D, E). Intronic in situ probes, however, reveal no differences in expression among embryos from the same clutch, n=30/30 (X2=10.0, p=0.0016) and n=45/45 (X2=15.0, p=0.0001), respectively (C, F). These results are consistent with previous observations in torb644 mutants using intronic and exonic in situ probes that distinguish nascent from processed transcripts (Dill et al, 2005).
