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.

The Mitochondrial Genome of Littoraria melanostoma Reveals a Phylogenetic Relationship within Littorinimorpha

“…genome sequences to analyze the phylogenic relationship between the genera Littorina and Littoraria, but only four species were used in this study [17]. The phylogeny of Stromboidea, a superfamily in Littorinimorpha, was studied based on 13 mitochondrial proteincoding genes [18].…”

“…Reid et al used nuclear 28S rRNA, mitochondrial 12S rRNA, and COI to construct the phylogeny of the family Littorinidae [12] and the genus Littoraria [16]. Li et al used complete mitochondrial genome sequences to analyze the phylogenic relationship between the genera Littorina and Littoraria, but only four species were used in this study [17]. The phylogeny of Stromboidea, a superfamily in Littorinimorpha, was studied based on 13 mitochondrial protein-coding genes [18].…”
