Volcano plot displaying differentially expressed miRNAs identified using miRNA-seq in Tibetan and Yorkshire pigs.

<p>The y-axis represents the mean expression value of log10 (<i>P</i>-value) and the x-axis displays the log₂-fold change value. Up-regulated and downregulated miRNAs are shown in red and green, respectively. Black dots indicate genes with no significant change in expression.
