Most 3′ fragments of cleaved miRNA targets overaccumulate in xrn4 as polyadenylated RNA. (A) Decay plots (D-plots) of a validated miRNA target transcript ARF10 that overaccumulates 3′ fragment of miR160-guided cleavage in xrn4–5. Black arrow, miRNA-guided cleavage site. (B) The heat map of miRNA targets shows fold changes of 3′ fragment abundance in xrn4 in polyA+ and polyA- PARE (Supplementary Table S3). Abundance at cleavage site (±1 nt) in both xrn4 mutants ≥ 10 TP20M and ≥1.5-fold change.
