Transposons and repeats are targeted by common small RNAs in mosquito cells and tissues. (A) Profiles of the transposons and repeats with the most abundant small RNAs both in cell cultures and mosquito tissues. Positive strand reads are in red; minus-strand reads are in blue. The x-axis gives the coordinates of the transposon and repeats sequence; the y-axis is the autoscaled read frequency. The total small RNA normalized counts are below each plot. (B) Comparisons of Dipteran genome sizes, fraction of the genome as repeats, average percentage of the small RNAs targeting mosquito transposons and repeats, and the average ratios of the repeat-targeting small RNAs being antisense or the same sense as the repeats.
