Fig. 6. The transcriptome maintains a steady-state distribution of transcript abundances during early embryogenesis. (A) A histogram plotting the distribution of transcript abundances among the RD genes for each of twelve time points assayed. Binned units along the x-axis are transcripts per embryo and the y-axis relates how many of the genes RD in that time point are in each bin. (B) A histogram plotting the distribution of rates of change in transcript abundance for each of ten time intervals. Binned units along the x-axis are transcripts per minute per embryo and the y-axis relates how many genes fall into each bin (note log scale). Time intervals are equivalent to those in Fig. 4A. Rates were calculated by dividing the difference in abundance between timepoints by the corresponding time interval, and converting to transcripts min^-1 embryo^-1, assuming 10⁷ transcripts per embryo. Only those RD genes with P<0.05 in the paired-time point ANOVA corresponding to each time interval are included.
