Project description:Abstract We sequenced and annotated the complete mitochondrial genome (mitogenome) of Takydromus kuehnei Van Denburgh, 1909 (Squamata: Takydromus). This mitogenome was 17,224 bp long and encoded 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, one non-coding regions of an L-strand replication origin and a displacement loop region. The overall nucleotide composition was 32.8% of A, 13.8% of G, 24.8% of T, and 30.5% of C. Phylogenetic analysis using maximum likelihood method validated the taxonomic status of T. kuehnei, exhibiting the close relationship with the species from the genus Takydromus.

Project description:The complete mitogenome sequence of Takydromus amurensis (Squamata: Lacertidae) is determined using long PCR for the first time in this study. It is a circular molecule of 17 333 bp in length (GenBank accession number: KU641018). Similar to the most other lizards, the complete mtDNA sequence of T. amurensis contained two rRNA genes (12S rRNA and 16S rRNA), 22 tRNA genes, 13 protein-coding genes (PCGs) and a control region (D-loop). The nucleotide composition was 31.23% A, 26.06% C, 13.91% G and 28.8% T. Mitochondrial genomes analyses based on NJ method yield phylogenetic trees, including 14 reported lizards belonging to three families (Lacertidae, Gekkonidae and Agamidae). These molecular data presented here provide a useful tool for systematic analyses of genus Takydromus.

Project description:The complete mitochondrial genome sequence of Takydromus septentrionalis was determined by shotgun sequencing. The total length of mitogenome is 18,304 bp, and contains 13 protein-coding genes, 22 tRNA genes, 2 ribosome RNA genes, and 2 control regions. Most of the genes of T. septentrionalis were distributed on the H-strand, except for the ND6 subunit gene and eight tRNA genes which were encoded on the L-strand. The phylogenetic tree of T. septentrionalis and 8 other closely related species was reconstructed. The phylogenetic analyses based on these mitogenomes presented here will be useful for further insights on the evolutionary relationships of Takydromus.

Project description:One of the main functions of physiological color change is thermoregulation. This change occurs much more rapidly than morphological color change, but the underlying mechanism remains poorly understood. Here, we studied the thermal dependence and molecular basis of physiological color change in lizards using Takydromus septentrionalis (Lacertidae) as the model system. Body color was thermally sensitive, becoming increasingly light as body temperatures deviated from the level (∼30°C) preferred by this species. We identified 3389 differentially expressed genes (DEGs) between lizards at 24°C and 30°C, and 1,097 DEGs between lizards at 36°C and 30°C. Temperature affected the cAMP signal pathway, motor proteins, cytoskeleton, and the expression of genes related to melanocyte-stimulating hormone (MSH) and melanocyte-concentrating hormone (MCH). Our data suggest that the role of physiological color change in thermoregulation is achieved in T. septentrionalis by altering the arrangement of pigments and thus the amount of solar radiation absorbed and reflected. G protein-coupling system inhibits adenylate cyclase activity to transform ATP into cAMP and thereby causes rapid pigment aggregation. MCH deactivates the G proteins and thereby initiates pigment dispersion. This mechanism differs from that reported for teleost fish where MCH activates the G proteins and thereby causes pigment aggregation.This article has an associated First Person interview with the first author of the paper.

Project description:A new species, Takydromus yunkaiensis J. Wang, Lyu, & Y.Y. Wang, sp. nov. is described based on a series of specimens collected from the Yunkaishan Nature Reserve located in the southern Yunkai Mountains, western Guangdong Province, China. The new species is a sister taxon to T. intermedius with a genetic divergence of 8.0-8.5% in the mitochondrial cytochrome b gene, and differs from all known congeners by a combination of the following morphological characters: (1) body size moderate, SVL 37.8-56.0 mm in males, 42.6-60.8 mm in females; (2) dorsal ground color brown; ventral surface green to yellow-green, but light blue-green on chin and throat, posteriorly green in adult males; (3) dorsolateral lines paired, strikingly yellowish-white bordered by black above and below, invisible or indistinct in juveniles and adult females; (4) flanks of body blackish brown with light brown marks in adult males; (5) presence of four pairs of chin-shields; (6) four supraoculars on each side; (7) presence of a row of supracilary granules that separate supracilaries from supraoculars; (8) two postnasals; (9) enlarged dorsal scales in six longitudinal rows on trunk of body, with strong keel; (10) enlarged ventral scales in six longitudinal rows, strongly keeled in males, smooth but outermost rows weakly keeled in females; (11) enlarged and keeled lateral scales in a row above ventrals; (12) femoral pores 2-3 on each side; (13) subdigital lamellae 20-23 under the fourth finger, 23-30 under the fourth toe; and (14) the first 2-3 subdigital lamellae under the fourth toe divided. The discovery of Takydromus yunkaiensis sp. nov. brings the total number of species of this genus to 24, of which nine occur in mainland China.
