Abstract
The mitochondrial DNA of the rice frog, Fejervarya limnocharis (Amphibia, Anura), was obtained using long-and-accurate polymerase chain reaction (LA-PCR) combining with subcloning method. The complete nucleotide sequence (17,717 bp) of mitochondrial genome was determined subsequently. This mitochondrial genome is characterized by four distinctive features: the translocation of ND5 gene, a cluster of rearranged tRNA genes (tRNA(Thr), tRNA(Pro), tRNA(Leu) ((CUN))) a tandem duplication of tRNA(Mer) gene, and eight large 89-bp tandem repeats in the control region, as well as three short noncoding regions containing two repeated motifs existing in the gene cluster of ND5/tRNA(Thr)/tRNA(Pro)/tRNA(Leu)/tRNA(Phe). The tandem duplication of gene regions followed by deletions of supernumerary genes can be invoked to explain the shuffling of tRNAM(Met) and a cluster of tRNA and ND5 genes, as observed in this study. Both ND5 gene translocation and tandem duplication of tRNA(Met) were first observed in the vertebrate mitochondrial genomes. (c) 2004 Elsevier B.V. All rights reserved.
