Figure 4.

Scatter plot of endo-siRNA read count versus distance to the neighboring gene. Left panel, genes arranged head to head (divergent transcription); middle, genes in tail to head orientation; right panel, genes in tail to tail arrangement (convergent transcription). The R2 values indicate a lack of correlation in all three panels.
