Abstract

Complete mitochondrial genome sequence of Rivularia auriculata has a circular genome of 16,552 bp, which is comprised 13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes. The nucleotide composition of the light strand is 43.16% of A, 26.78% of T, 20.18% of C, and 9.88% of G. All genes are encoded on the heavy strand except seven tRNA genes (Met, Tyr, Cys, Trp, Gln, Gly, and Glu) on the light strand. All the protein-coding genes start with ATC initiation codon except ND4 starts with GTG, and two types of inferred termination codons are TAA and TAG. There are 26 intergenic spacers and 4 gene overlaps. It is indicated that R. auriculata has closer genetic relationship with Viviparus chui (88.64% nucleotide sequence identity between them) than the other snail species.
