Figure 4From: Characterization and expression patterns of let-7 microRNA in the silkworm (Bombyx mori)Phylogenetic tree based on the selected precursors of let-7 family members. In order to be convenient for analysis, we selected 26 representative let-7 precursors. Phylogenetic tree was constructed using MEGA v3.0 with 1000 times bootstrap sampling. Full species names coresponding to the microRNAs are as follows: hsa, Homo sapiens; fru, Fugu rubripes; dre, Danio rerio; xtr, Xenopus tropicalis; bta, Bos taurus; cbr, Caenorhabditis briggsae; cel, Caenorhabditis elegans; bmo, Bombyx mori; dme, Drosophila melanogaster; dps, Drosophila pseudoobscura; aga, Anopheles gambiae; ssc, Sus scrofa; tni, Tetraodon nigroviridis.Back to article page
