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

¹Clusters were ordered and numbered according to the abundance of cluster unique piRNAs in both studies. Cluster 6 from Brennecke et al. (2007) was not reported here because it was not located on an assembled portion of the published D. melanogaster BGDP 5 genome.
²"Cluster unique piRNAs" were defined as piRNA sequences that mapped in only one location in the genome and inside a cluster.
³"N/A" indicates the absence of any overlapping piRNA cluster in present study.
