Gene rearrangements in gekkonid mitochondrial genomes with shuffling, loss, and reassignment of tRNA genes.

ABSTRACT:

Background

Vertebrate mitochondrial genomes (mitogenomes) are 16-18 kbp double-stranded circular DNAs that encode a set of 37 genes. The arrangement of these genes and the major noncoding region is relatively conserved through evolution although gene rearrangements have been described for diverse lineages. The tandem duplication-random loss model has been invoked to explain the mechanisms of most mitochondrial gene rearrangements. Previously reported mitogenomic sequences for geckos rarely included gene rearrangements, which we explore in the present study.

Results

We determined seven new mitogenomic sequences from Gekkonidae using a high-throughput sequencing method. The Tropiocolotes tripolitanus mitogenome involves a tandem duplication of the gene block: tRNAArg, NADH deh
