The importance of wild barley from Qinghai-Tibet Plateau in the origin and domestication of cultivated barley has long been underestimated. Population-based phylogenetic analyses were performed to study the origin and genetic diversity of Chinese domesticated barley, and address the possibility that the Tibetan region in China was an independent center of barley domestication. Wild barley (Hord...
How and when India collided with Asia is crucial for global climate and continental dynamics. We present new palaeomagnetic data showing that the Xigaze forearc basin of southern Tibet was located at 24.2 ± 5.9°N during 54-57 Ma, providing a direct constraint on the position of the southernmost margin of Asia at this crucial stage. Our study suggests 1) the age and locus of the initial India-As...
PREMISE OF THE STUDY Saxifraga egregia (Saxifragaceae) is a perennial herb that is endemic to the Qinghai-Tibet Plateau. We developed 12 polymorphic microsatellite loci for S. egregia to investigate its population genetics. METHODS AND RESULTS Forty-eight pairs of microsatellite primers (including 36 monomorphic loci) were isolated and characterized by magnetic bead enrichment. Twelve of thes...
Magnetotelluric exploration has shown that the middle and lower crust is anomalously conductive across most of the north-to-south width of the Tibetan plateau. The integrated conductivity (conductance) of the Tibetan crust ranges from 3000 to greater than 20,000 siemens. In contrast, stable continental regions typically exhibit conductances from 20 to 1000 siemens, averaging 100 siemens. Such p...
Lactobacillus helveticus strain H10 was isolated from traditional fermented milk in Tibet, China. We sequenced the whole genome of strain H10 and compared it to the published genome sequence of Lactobacillus helveticus DPC4571.
Most of the Chinese species of the tribe Podoscirtini are distributed in southern areas of China, especially in Yunnan Province and Hainan Island (Eades et al. 2015). Motuo County is located in southeast Tibet. In this area, altitude decreases from north to south sharply. The climate in Motuo is wet and warm, which makes the animals and plants are very different from those elsewhere in Tibet (F...
Sherpas living around the Himalayas are renowned as high-altitude mountain climbers but when and where the Sherpa people originated from remains contentious. In this study, we collected DNA samples from 582 Sherpas living in Nepal and Tibet Autonomous Region of China to study the genetic diversity of both their maternal (mitochondrial DNA) and paternal (Y chromosome) lineages. Analysis showed t...
The Chinese species of the silphaeformis group of the genus Tachinus Gravenhorst are revised with fifteen species being treated. Thirteen of them are described as new: T. armatus Feng & Li, sp. n. (Sichuan), T. cavazzutii Feng, Li & Schülke, sp. n. (Sichuan), T. coronatus Feng, Li & Schülke, sp. n. (Ningxia, Qinghai), T. hercules Feng, Li & Schülke, sp. n. (Sichuan), T. hujiayaoi Feng, Li & Sch...
A new map and cross sections of the Khula Kangri and Kankar Pünzum-Monlakarchung High Himalayan ranges in the Tibet-Bhutan frontier area are presented from integration of unpublished mapping from the summit section of Khula Kangri and new remote sensing together with previous mapping. The ranges define an orographic bifurcation of the High Himalaya that results in a north-south repetition of th...
