| Abstract: | A nucleotide sequence analysis of ribosomal internal transcribed spacer 2(ITS2) gene fragment from five species unionicolid mites was performed.It was found that the aligned nucleotide fragment is 258 bp(including gap) in length,including 186 conserved sites,57 variable sites.The total variable rate is 22.1% and interspecific variable rate values vary from 7.4% to 14.9%.There are 11 transition sites and 18 transversion sites,and the ration of transition/transversion is 0.61.In the nucleotide sequence,the co... |
