Characterization of the complete mitochondrial genome of Conus tribblei Walls, 1977

Abstract

The genus Conus sensu lato consists of 500–700 species. However, the mitochondrial genomes of only few species have been fully sequenced and reported so far. In this study, the complete mitochondrial genome of Conus tribblei, a member of the poorly known subgenus Splinoconus is sequenced with the mean coverage of 604×. The mitochondrial genome is 15 570 bp long and consists of genes encoding for 13 respiratory chain proteins, 22 tRNA and 2 rRNA. The gene organization is highly conserved among the Conus species. The longest intergenic region between tRNA-Phe and cytochrome c oxidase subunit III (cox3), which in C. tribblei is 169 bp long and contains a 112 bp long segment of inverted repeat, represents the putative control region. The control regions of Conus species exhibited variability in the length and position of the inverted repeats. Therefore, this region may have the potential to be used as a genetic marker for species discrimination.

Declaration of interest

The specimen used in this study was obtained in conjunction with a collection trip supported in part by ICBG grant #1U01TW008163. This study was supported by a grant to AOL from the Emerging Interdisciplinary Research Program of the University of the Philippines System through the Philippine Genome Center. The data analysis was carried out using the high-performance computing systems at the Philippine Genome Center. The mitochondrial genome sequence of C. tribblei is deposited in the GenBank database under the accession number KT199301. The authors report no conflicts of interest.
