title: Cousinia proxima
design: The PCR products were purified using the AMPure XP system from Beverly, USA. The quality of the libraries was evaluated using the Agilent 5400 system from Agilent, USA, and their concentration was determined by QPCR (1.5 nM). The qualified libraries were combined and sequenced on Illumina platforms using the PE150 strategy at Novogene Bioinformatics Technology Co., Ltd in Beijing, China, according to the required library concentrations and data volume
