%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 dataset focuses on the semi-arid desert in central and eastern Inner Mongolia as the core survey area, and investigates the main desert plants in the four major sandy areas in northern China and surrounding areas from 2017 to 2021, and collects DNA molecular materials. According to project requirements, sequence 5 DNA barcode fragments (rbcL, matK, psbA trnH, trnL-F, ITS) from each plant material. This data set contains 352 copies and 1760 pieces of DNA barcodes, including 56 copies and 280 pieces of plant DNA barcodes in Hulunbeier Sandy Land, 73 copies and 365 pieces of plant DNA barcodes in Horqin Sandy Land, 133 copies and 665 pieces of plant DNA barcodes in Hunshandake Sandy Land, and 90 copies and 450 pieces of plant DNA barcodes in Maowusu Sandy Land.
