Table 5 Number and percent abundance of piRNA and siRNA sequences in Ae. aegypti and D. melanogaster libraries, as well piRNA and siRNA sequences matching known TE sequences

From: The mosquito Aedes aegypti has a large genome size and high transposable element load but contains a low proportion of transposon-specific piRNAs

  1. Numbers in parentheses exclude duplicate sequences.
  2. 1 TE elements such as Penelope that cannot be put into any of the other categories.
  3. 2 Indicates that no elements from these categories have been reported in D. melanogaster.
