Results: expression analysis. Results of the host gene cluster based expression analysis. Grey bars denote the number of all identified host gene clusters including unclustered hosts with expressed target genes, predicted by Pictar (PT), TargetScan (TS), RNA22 (R) and our consensus model (CM). Orange bars denote the number of clusters with significantly correlated target gene expression patterns. The relative fraction of significant clusters for each dataset and miRNA target prediction tool is denoted.
