The size distribution and assignment of piRNAs relative to genome complexity in Ae. aegypti. A) Size distribution of Ae. aegypti small RNA abundance in a representative library (library 1). The number of small RNAs mapping to Ae. aegypti genes, transposons, both, or neither, are shown as different colors for each size class (the legend is shown on the right). B) Relative distribution of nucleotide abundance at Ae. aegypti small RNA positions for small RNAs targeted to transposons, genes and other sequences. The graph was drawn using using Weblogo . C) Percentage of the sequenced Ae. aegypti genome occupied by genes, transposon, both, or neither (the legend is shown on the right).
