Summary of the disruption rates of the abundant genes.

The genes of high abundance (normalized percentage >0 in Fig. 5a) were used for the estimation of disruption rate. The gene number differed among the samples. The lengths of the reads and the ORFs identified therein were averaged. The RRP is the ratio of real average ORF length to predicted ORF length (see Materials and Methods). The disruption rate was estimated on the basis of a simulation in reference to the RRP value. SD, standard deviation.
