%X This dataset is based on raw sequence data, which has been double compared with GenBank and local databases, and further analyzed using genetic distance analysis (such as Barcoding Gap and sequence similarity comparison) and phylogenetic tree analysis to systematically eliminate low-quality and redundant sequences. This processing flow significantly improves the accuracy of species identification and the overall reliability of the database, ultimately constructing a high-quality DNA barcode reference database for seed plants in arid regions of China. We have also updated the v2 version of the database, which contains sequence data that has been synchronized and made public in GenBank, in order to provide a more solid, continuously updated, and publicly accessible data foundation for regional biodiversity monitoring and protection.  This data set takes the Tarim Basin and the Junggar Basin in Xinjiang as the core survey areas, taking into account the surrounding Kashgar, Shache, Hotan, Ruoqiang, Aksu, Ili, Tacheng and Turpan, etc., and investigated the main desert plants in these areas in 2017-2021, and collected samples and DNA molecular materials. According to project requirements, sequence 5 DNA barcode fragments (ITS, matK, rbcL, trnL-F, trnH psBA) from each plant material. This dataset contains 1002 copies of 4631 DNA barcodes, including 1317 copies of 331 plant DNA barcodes in Tarim Basin and 3314 copies of DNA barcodes in the Junggar Basin.
