Deep sequencing of small RNA populations in Ae. albopictus C7/10 cells and Cx. quinquefasciatus mosquitoes. Size distributions of small RNA libraries (18-28 nt) from A) C7/10 cells (Aedes) and B) Cx. quinquefasciatus (Culex). C) Frequencies of read counts for individual, conserved miRNAs present in C7/10 cells and Culex mosquitoes. Expression levels, based on read counts, of individual miRNAs are separated into several ranges and span over 5 orders of magnitude. D) Breakdown of the total number of reads obtained for each library. The number of reads mapping to miRNA and miRNA* strands is reported.
