Only one-third of the Tribolium miRNA sequences are conserved in D. melanogaster, and at least 18 Tribolium miRNAs are conserved in vertebrates but lost in Drosophila. More than one-fifth of miRNAs that are conserved between Tribolium and Drosophila exhibit changes in the transcription, genomic organization, and processing patterns that lead to predicted functional shifts. For example, 13% of conserved miRNAs exhibit seed shifting, and we describe arm-switching events in 11% of orthologous pairs.
