The complete nucleotide sequence of the mitochondrial genome of f . limnocharis was detailedly compared with those of 5 other amphibians . the nucleotide sequences of 22 trna encoded by 6 amphibians mitochondrial genomes were combined and aligned to the homologous sequences of the 11 veterbrate taxa . using teleosts as outgroup , the phylogenetic analyses results show that mp , nj and ml trees all strongly support the monophyly of living amphibians with respect to other living tetrapods and favor a sister group relationship for caecilians and salamanders 我们在测定了泽蛙线粒体全基因组序列的基础上，与已知其它的5种两栖类进行详细的比较分析，同时选择了11种高等脊椎动物的线粒体全基因序列，以硬骨鱼类做外群，用22个trna基因合并数据进行系统发生重建分析，结果表明mp 、 nj和ml树都强力地支持现生两栖类动物为单系群并且蝾螈类和蚓螈类为姐妹群关系(自引导值分别为92 、 99 、 100 ) 。
