Coverage of RNA-seq reads from 16S and 23S rRNAs from 2-, 47-, and 98-day spores. RNA-seq data for two sets of rRNA genes, rrnO and rrnH, which exhibited lower (rrnO) and higher (rrnH), respectively, loss of reads in regions of 47- and 98-day spore rRNA are shown, and coverage of reads was determined as described in Materials and Methods. The vertical axes are coverage in arbitrary units (a.u.). Note that the scales of the vertical axes are identical for 2-, 47-, and 98-day spore rRNA.
