The mitochondrial genome of Diaphanosoma excisum Sars, 1885 (Crustacea: Branchiopoda: Cladocera) from Hainan Island, China

Diaphanosoma excisum is the only Cladoceran in tropical freshwaters and parapatrically occurs with Diaphanosoma dubium in the transition between the tropics and subtropics. Here, we present the complete mitochondrial genome (MG) determined by next-generation sequencing and offer a phylogenetic analy...

Sumario:Diaphanosoma excisum is the only Cladoceran in tropical freshwaters and parapatrically occurs with Diaphanosoma dubium in the transition between the tropics and subtropics. Here, we present the complete mitochondrial genome (MG) determined by next-generation sequencing and offer a phylogenetic analysis of D. excisum. The MG of D. excisum is 17,615 bp in size, including 13 protein-coding genes (PCGs), 2 ribosomal RNA, 23 tRNA, and 2 putative control regions. The MG has a biased A + T of 65.34% for base composition. Compared to D. dubium, the MG of D. excisum has one more tRNA-Met, one unknown extra putative control region and is different in the arrangement of its tRNAs. The MG sequence and tRNA order provide valuable molecular data for understanding the phylogeny and speciation of Diaphanosoma.
