Expression patterns of pairs of neighboring miRNAs. A Clustered miRNAs show similar expression patterns. Tracks: 1. Linkage groups. 2. Name of clustered miRNAs. 3. miRNA loci, clustered miRNAs at adjacent positions, are displayed in a stacked style. 4. MiRNA expression level (log2 of normalized count add 1), from inside out: muscle, intestine, heart, hatching stage, gill, brain. B Expression profiles of miRNA genes. Tracks: 1. MiRNA expression level (log2 of normalized count add 1, in the same order as in plot A). 2. phylogeny of miRNA sequences. C Correlation between expression patterns of pairs of neighboring miRNAs. Expression correlations were calculated using data in Table S4. D Effects of distance and duplication, including remote (trans-) and local (cis-) miRNA duplication on miRNA expression. Only those miRNAs with well-defined duplicate types were considered (Table S5). E Specific miRNAs clustered with other miRNAs show significantly higher expression than specific single miRNAs. Comparisons between groups were analyzed by one-way analysis of variance (ANOVA). *p < 0.05 and **p < 0.01 indicated statistical significance
