关 键 词：Mantodea mitochondrial genome gene duplication phylogeny
摘 要：We acquired 21 complete mitogenomes and 6 nearly complete mitogenomes of mantises belonging to 8 families(Hymenopodidae,Iridopterygidae,Mantidae,Metallyticidae,Sibyllidae,Tarachodidae,Thespidae,Toxoderidae)using 14 pairs of mantid specific primer sets and found that 5 species of mantises have duplicate copies(2-4)of trnR:Ambivia undata,Creobroter jiangxiensis,Creobroter urbanus,Phyllothelys *** Theopropus elegans while two novel gene arrangements CR-I-NCR-I-NCR-I-NCR-I-NCR-I-NCR*-Q-M and COII-K*-D*-K-D*-K-D*-K-D were found in Schizocephala bicornis and Stenotoxodera porioni,*** multiple copies of trnR are caused by independent *** gene arrangements in Stenotoxodera porioni with three identical copies of trnK can be explained as mid-way through the TDRL process while the form of gene arrangement in Schizocephala bicornis is *** the phylogeny at the family level,the monophyly of Liturgusidae and Iridopterygidae was supported,whereas the monophyly of Hymenopodidae,Mantidae and Tarachodidae wasn’*** features of mantis mitochondrial genomes including high duplication rates of trnR,trnK and trnl indicate that Mantodea mitochondrial genomes maybe a useful model system for studying gene ***,derived gene arrangements may not be appropriate for phylogenetic inference in Mantodea as they aren’t synapomorphy and aren’t shared by close relatives.
