Project description:Land cover change has long been recognized that marked effect the amount of soil organic carbon. However, little is known about microbial-mediated effect processes and mechanism on soil organic carbon. In this study, the soil samples in a degenerated succession from alpine meadow to alpine steppe meadow in Qinghai-Tibetan Plateau degenerated, were analyzed by using GeoChip functional gene arrays.

Project description:Tibetan's adaptation to high-altitude environment at the Qinghai-Tibetan plateau represents a remarkable case of natural selection during recent human evolution. We generated time series paired RNAseq, ATACseq and Hi-C data in Tibetan and Han Chinese's umbilical endothelial cells from normoxia to hypoxia condition. Our results provide a broad resource of genome-wide hypoxia regulatory network to characterize the effect of genetic variation in high-altitude adaptation, and indicates large-scale maps of variants need proper cell types to understand its act on gene regulation.

Project description:Long term-exposed to high altitude, the increased numbers of red blood cells tend to stabilize to a certain extend in most people, but someone will occur over-increasing in number of red blood cells, which cause a serious of clinical symptoms and signs, and this is high altitude polycythemia. EPO-EPOR system may be the main reasons for erythroid progenitor cell proliferation and differentiation in early exposion to plateau, but, in the late, there may be other factors involved in the regulation of erythropoiesis in bone marrow, multiple factors working together lead to excessive red blood cell proliferation. We compared gene expression profiling of leukocytes in peripheral blood from high altitude polycythemia patients with those from matched controls. Subjects consisting of 5 masculine Han Chinese patients with HAPC (diagnosed according to international consensus statement on HAPC) and 5 matched controls, were migrants at River of TUOTUO area (Qinghai-Tibetan Plateau, 4550 m). Each of the five HAPC patients was matched to each of the control: gender, nationality, birthplace, duration migrating to plateau, height of location, work intensity. Peripheral blood samples were obtained at 4550m plateau from above subjects. Total RNA was extracted from peripheral blood leucocytes. The gene expression profilings were analysed by Human Genome U133 Plus 2.0 Array.

Project description:Tibetan chicken has a suite of adaptive features to tolerate the high-altitude hypoxic environment as a unique native breed in Qinghai-Tibet Plateau of China. Increasing evidence suggests that long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) have roles in hypoxic adaptation of high-altitude animals, though their exact contributions remain unclear. This study aims to uncover the global landscape of mRNAs, lncRNAs and miRNAs using transcriptome sequencing so as to construct a regulatory network of competing endogenous RNAs (ceRNAs) provide a new sight for the hypoxic adaptation of Tibetan chicken embryos. In the study, 354 differentially expressed mRNAs (DEGs), 389 differentially expressed lncRNAs (DELs) and 73 differentially expressed miRNAs (DEMs) were identified between Tibetan (TC) and Chahua chicken (CH). The functional analysis showed that several important DEMs and their targets of DELs and DEMs are involved in angiogenesis (include blood vessel development and blood circulation) and energy metabolism (include glucose, carbohydrate and lipid metabolism). The ceRNA network was then constructed with the predicted pairs of DEGs-DEMs-DELs which further revealed regulatory roles of these differentially expressed RNAs in hypoxic adaptation of Tibetan chicken.

Project description:The extreme environments of the Tibetan Plateau offer significant challenges to human survival, demanding novel adaptations. While the role of biological and agricultural adaptations in enabling early human colonization of the plateau has been widely discussed, the contribution of pastoralism is less well understood, especially the dairy pastoralism that has historically been central to Tibetan diets. Here, we analyze preserved proteins from the dental calculus of 40 ancient individuals to report the earliest direct evidence of dairy consumption on the Tibetan Plateau. Our palaeoproteomic results demonstrate that dairy pastoralism began on the higher plateau by approximately 3,500 years ago, more than 2,000 years earlier than the recording of dairying in historical sources. With less than 1% of the Tibetan Plateau dedicated to farmland, pastoralism and the milking of ruminants were essential for large-scale human expansion into agriculturally-marginal regions that make up the majority of the plateau. Dairy pastoralism allowed conversion of abundant grasslands into nutritional human food, which facilitating adaptation in the face of extreme climatic and altitudinal pressures, and maximizing the land area available for long-term human occupation of the “roof of the world”.

Project description:Protein abundance changes and reversible protein phosphorylation (RPP) play important roles in regulating hypometabolism but have never been documented in overwintering frogs at high altitudes. To test the hypothesis that protein abundance and protein phosphorylation change in response to winter hibernation, we conducted a comprehensive and quantitative proteomic and phosphoproteomic analysis of the liver of the Xizang plateau frog, Nanorana parkeri, living on the Qinghai-Tibet Plateau.

Project description:Morphological plasticity of ectomycorrhizal (EcM) short roots (known also as first and second order roots with primary development) allows trees to adjust their water and nutrient uptake to local environmental conditions. The morphological traits (MTs) of short-living EcM roots, such as specific root length (SRL) and area, root tip frequency per mass unit (RTF), root tissue density, as well as mean diameter, length, and mass of the root tips, are good indicators of acclimation. We investigated the role of EcM root morphological plasticity across the climate gradient (48-68°N) in Norway spruce (Picea abies (L.) Karst) and (53-66°N) birch (Betula pendula Roth., B. pubescens Ehrh.) forests, as well as in primary and secondary successional birch forests assuming higher plasticity of a respective root trait to reflect higher relevance of that characteristic in acclimation process. We hypothesized that although the morphological plasticity of EcM roots is subject to the abiotic and biotic environmental conditions in the changing climate; the tools to achieve the appropriate morphological acclimation are tree species-specific. Long-term (1994-2010) measurements of EcM roots morphology strongly imply that tree species have different acclimation-indicative root traits in response to changing environments. Birch EcM roots acclimated along latitude by changing mostly SRL [plasticity index (PI) = 0.60], while spruce EcM roots became adjusted by modifying RTF (PI = 0.68). Silver birch as a pioneer species must have a broader tolerance to environmental conditions across various environments; however, the mean PI of all MTs did not differ between early-successional birch and late-successional spruce. The differences between species in SRL, and RTF, diameter, and length decreased southward, toward temperate forests with more favorable growth conditions. EcM root traits reflected root-rhizosphere succession across forest succession stages.
