title: The complete maternal mitochondrial genome of rare Chinese freshwater mussel Lepidodesma languilati (Bivalvia: Unionidae: Unioninae).
abstract: Lepidodesma languilati is considered threatened because of the influence of human activities in China. The complete F-type mitochondrial genome of L. languilati was determined in this study (GenBank accession no. KT381195). It is a 15 754-bp-long circular molecule that consists of 37 genes that are typically found in other invertebrates. The overall base composition of the entire sequence is as follows: A (39.1%), T (25.7%), C (23.4%), and G (11.8%). Except for cox1 (TTG), cob (ATT), nad1 (ATT), nad6 (ATA), nad4 (TTG), and atp8 (GTG), 7 of the 13 protein-coding genes initiate with orthodox ATG start codon. All the 13 protein-coding genes have complete termination codon TAA or TAG. Phylogenetic tree indicates that L. languilati belongs to Unioninae. The newly sequenced complete mitogenome can provide basic data for comparative studies on mitochondrial genomes of Unionidae. It could also lay the important theoretical foundation for phylogenetics, population genetics, germplasm resources protection, sustainable, and reasonable utilization.
