caecitis

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 我們在測定了澤蛙線粒體全基因組序列的基礎上,與已知其它的5種兩棲類進行詳細的比較分析,同時選擇了11種高等脊椎動物的線粒體全基因序列,以硬骨魚類做外群,用22個trna基因合并數據進行系統發生重建分析,結果表明mp 、 nj和ml樹都強力地支持現生兩棲類動物為單系群并且蠑螈類和蚓螈類為姐妹群關系(自引導值分別為92 、 99 、 100 ) 。
