First mitochondrial genome of a periwinkle from the genus Littoraria: Littoraria sinensis.

ABSTRACT

The nearly complete sequence of the mitochondrial genome of the periwinkle Littoraria sinensis is presented. This is the first mitochondrial genome of the genus Littoraria and the fifth sequenced Littorinidae. The mitogenome of L. sinensis is 16,320 bp in size, with 37 genes and one partial control region. The genes order is identical to those observed in other Littorinidae mitogenomes. The overall base composition shows that AT content (64.76%) is higher than GC content (35.24%). This study should provide new information for the further phylogenetic studies of this species.
