Secondary siRNAs produced from targets of miRNAs* with a 22-nt miRNA. (A) Enrichment of miRNAs* in AGO1–co-IP fractions. Only miRNA*s that are enriched or depleted at least twofold in AGO1–co-IP fractions compared with the total small RNA population are shown. MiR173* is indicated with a red arrow. (B) Small RNAs mapping to At4g31560 cDNA. (C) RNA blots to detect miR173, miR173* and At4g31560-derived small RNAs (“siRNA”) in transitivity defective mutants. (D) RNA blot to detect At4g31560-derived small RNAs in different ago mutants.
