Phylogenetic evolution of locust conserved miRNA families. (a) Phylogenetic distribution of 50 conserved miRNA families of the locust. A plus (+) symbol indicates this miRNA family is found in the species named on the left, and a minus (-) symbol means it is absent in that species. A red plus symbol means this miRNA family can not be found in any database, but was found by our search in the corresponding species genome. (b) An example of clade-specific conserved miRNAs based on sequence substitutions. The red nucleotides indicate the positions that are the same among vertebrates but different from insects, which are shown in green. Vertebrates and insects can be easily separated according to sequence differences in their miR-190, showing the different sequence features of conserved miRNAs in different clades. The asterisks indicate the conserved sites among these species. (c) Two conserved miRNA families whose sequences are unique in the locust (lmi). The red nucleotide shows the locust-specific position that is different from any other species. The asterisks indicate the conserved sites among these species.
