The amplified fragments were sequenced by Illumina Miseq PE250. The original data is analyzed by Qiime software, and then the similarity between sequences is calculated, and the sequences with a similarity of more than 97% are clustered into an OTU. The Greengenes reference library is used for sequence alignment to remove the sequence that only appears once in the database. The soil moisture content and soil temperature were measured by a soil hygrometer, and the soil pH was measured by a pH meter (Sartorius PB-10, Germany). The soil nitrate nitrogen (NO3 −) and ammonium nitrogen (NH4+) concentrations were extracted with 2 M KCl (soil/solution, 1:5), and analyzed with a Smartchem200 discrete automatic analyzer. This data set is of great significance to the study of soil microbial diversity in arid and semi-arid grasslands.

Equine genome sequencing data (2022)

In order to study the population evolution history and local adaptive genetic mechanism of the main domesticated equine animals in the Qinghai Tibet Plateau and its surrounding areas, and to establish the corresponding germplasm genetic resource bank. We sequenced the equine samples collected in Qinghai Province, Tibet Autonomous Region and Xinjiang Autonomous Region from the Qinghai Tibet Plateau and surrounding areas, including Tibetan donkey, plain donkey and other breeds. Sequencing includes denove and resequencing data, which provides data for tracing the historical events of domestication, migration, expansion and other groups of the main equine domesticated animals in the region, and further exploring the adaptation mechanism of equine animals to the harsh environment such as hypoxia, cold, and dryness. At the same time, all tissues of domestic donkeys were sequenced, including hifi genome data and HIC genome data, to prepare for the assembly of complete donkey genome and facilitate subsequent analysis.

Information and Photos of Lichen Specimens on the Tibetan Plateau (2019-2020)

Through the scientific research work in 2019 and 2020, the second Tibetan Plateau Scientific Expedition and Research Task 5 Theme 3 Topic 4 Lichen Scientific Research Team (2019QZKK050304) has supplemented the collection of a large number of lichen collection gaps in the Tibetan Plateau region. 2019 scientific research conducted in-depth lichen biodiversity examination for the first time in the Ali region in northern Tibet, and in 2020, fieldwork and specimen collection will be conducted in the lichen collection gap areas of Hoh Xil and Sanjiangyuan. These expeditions have unveiled the mystery of lichen composition in the Tibetan Plateau region and filled the gaps in the domestic collection of this region. This dataset contains information on 10,283 lichen specimens collected from July 2019 to September 2020 in Tibet Autonomous Region, Qinghai Province, Sichuan Province, and Yunnan Province, including information on collection habitat, collection time, collector, latitude and longitude, altitude, and Latin scientific name. Contains 4,328 specimen photos, including lichen specimen No. 815 in 2019 with 2,425 photos and specimen No. 543 in 2020 with 1,903 photos. The physical specimens are stored in the Herbarium, Kunming Institute of Botany, CAS (KUN). Specimen collection information and field ecological photographs are synchronized between various databases, including the Biotracks database and the KUN herbarium database, to facilitate later research, collation and query by relevant personnel. The specimens are now sorted by time, region and genus name and stored separately in the KUN herbarium to facilitate subsequent studies, and the corresponding molecular materials are preserved or molecular sequences are obtained, laying a good material basis for subsequent taxonomic and systematics studies of the specimens. DNA extraction and systematic taxonomic studies of various groups are also being carried out.
