  1. * Numbers of reads per sample obtained after mapping analyses are indicated together with their proportions relative to the total read numbers in parentheses.
  2. ** Estimated rRNA substitution rate, considering that 95% of the RNA was initially composed of rRNA.
  3. ***Only reads that uniquely mapped, and did not map rRNAs.
