The DNA sequence of the 3′-end of LSu-rRNA coding region of silkworm Attacus ricini was determined. By comparisons with the corresponding sequence of H. sapiens, X. leavis, H. momus, A. albopictus, D. melanogaster, C. elegants, S. pombe, M. musculus and M. racemosus, we found that the coding sequence we obtained is very conserved. Phylogenetic tree inferred by Neighbor-jioning Method showed that the rate of evolution of insects was much faster than vertebrate. In addition, the secondary structure has also worked out, it is highly conserved.
