Relation of hpa-sRNAs to genomic features. Size distribution of hpa-sRNAs mapping to single or multiple annotated features of the maize genome; 22-nt hpa-sRNAs map primarily to multiple annotations (repeat/intergenic, gene/repeat/intergenic), while 24-nt hpa-sRNAs map primarily to single annotations (intergenic or repeat)
