The Expression Plasticity of Hypoxia Related Genes in High-Altitude and Plains Nanorana parkeri Populations
For species that have a broad geographic distribution, adaptive variation may be attributable to gene expression plasticity. Nanorana parkeri is an anuran endemic to the southern Tibetan Plateau where it has an extensive altitudinal range(2850 to 5100 m asl). Low oxygen concentration is one of the main environmental characteristics of the Tibetan Plateau. Hypoxia-inducible factor α subunits(HIF-1α and HIF-2α, encoded by Endothelial PAS domain protein 1(EPAS1)) and associated genes(e.g., vascular endothelial growth factor(VEGF) and Erythropoietin(EPO)) play crucial roles in maintaining oxygen homeostasis. In this study, we compared the expression of HIF-1A, VEGF, EPAS1 and EPO mRNA between two populations of N. parkeri: one population inhabiting the native high altitudes, and the second living in, and being acclimated to, the lower plains(70 m asl). The expression of HIF-1A, VEGF and EPAS1 mRNA in the high altitude population were significantly higher than in the acclimated population, whereas there was no significant difference for EPO between two groups. Our results indicated that gene expression plasticity may make significant contributions to local adaptation of species that have broad altitudinal distributions. In addition, we deepen our understanding of the adaptive potential of this species by evaluating the experiments in the scope of its evolutionary history.
期刊介绍:
AHR aims to provide a forum for herpetologists and related scientists interested in conducting international academic exchanges and joint studies, and a platform for introducing their newly made scientific and technological data, and publishing their research results and achievements in the world, but focusing on the Asian-Pacific Region.
The principal criteria of AHR for acceptance of articles for publication are the quality and significance of the research, breadth of interest of the work to the readership, and the clarity and effectiveness of communication. AHR welcomes submission of manuscripts from authors in all countries of the world, though with a focus on the herpetological studies in the Asian and Pacific Region, including major articles, shorter communications and review articles.
