Complete mitochondrial genome sequence of the Asiatic Toad Bufo Gargarizans (Amphibia, Anura, Bufonidae).

ABSTRACT: The Asiatic toad Bufo gargarizans belongs to Bufonidae. This species is known from the Russian Far East, central, northern and north-eastern China, the Democratic People's Republic of Korea and Japan. In this study, the complete mitochondrial genome of B. gargarizans was sequenced. The mitogenome was 17,407?bp in length, consisting of 13 protein-coding genes, 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a non-coding control region. As in other vertebrates, most mitochondrial genes are encoded on the heavy strand, except for ND6 and eight tRNA genes which are encoded on the light strand. The overall base composition of the B. gargarizans is 28.9% A, 28.2% T, 27.5% C, and 15.3% G. Phylogenetic analysis showed B. gargarizans was closely related to B. bankorensis and B. tibetanus. The complete mitogenome of B. gargarizans can provide an important data for the studies on phylogenetic relationship and population genetics to further explore the taxonomic status of this species.

Project description:Hibernation is an effective energy conservation strategy that has been widely adopted by animals to cope with unpredictable environmental conditions. The liver, in particular, plays an important role in adaptive metabolic adjustment during hibernation. Mammalian studies have revealed that many genes involved in metabolism are differentially expressed during the hibernation period. However, the differentiation in global gene expression between active and torpid states in amphibians remains largely unknown. We analyzed gene expression in the liver of active and torpid Asiatic toads (Bufo gargarizans) using RNA-sequencing. In addition, we evaluated the differential expression of genes between females and males. A total of 1399 genes were identified as differentially expressed between active and torpid females. Of these, the expressions of 395 genes were significantly elevated in torpid females and involved genes responding to stresses, as well as contractile proteins. The expression of 1004 genes were significantly down-regulated in torpid females, most which were involved in metabolic depression and shifts in the energy utilization. Of the 715 differentially expressed genes between active and torpid males, 337 were up-regulated and 378 down-regulated. A total of 695 genes were differentially expressed between active females and males, of which 655 genes were significantly down-regulated in males. Similarly, 374 differentially expressed genes were identified between torpid females and males, with the expression of 252 genes (mostly contractile proteins) being significantly down-regulated in males. Our findings suggest that expression of many genes in the liver of B. gargarizans are down-regulated during hibernation. Furthermore, there are marked sex differences in the levels of gene expression, with females showing elevated levels of gene expression as compared to males, as well as more marked down-regulation of gene-expression in torpid males than females.
