Twenty-one–nucleotide small RNAs produced in wild-type A. thaliana from miRNA targets. (A) Bars indicate average number of Illumina reads from two biological replicates mapping to miRNA targets. Gray dots indicate average for individual targets among one miRNA family. (B) Size distribution of reads mapping to miRNA or miRNA*. Gray indicates miRNAs or miRNA*s that were not detected. For miRNA or miRNA* not detected in our data, other datasets were consulted (45).
