DNA barcode was proposed to speed documentation of biodiversity.As a coordinated effort to build a barcode library for major domains of life,DNA barcoding has greatly amplified our understanding of global biodiversity.According to the recently completed Flora of China,there are about 31362 species of 3328 genera of 312 families of vascular plants in China.By 2013,the Germplasm Bank of Wild Species at CAS Kunming Institute of Botany sequenced some 67000 barcodes,representing 23392 individuals of 7438 species in 1825 genera of 242 plant families,as an initial step to build up the framework of a reference library of the entire flora of China.It is hoped that a quarter of the species(ca.8000)and 80％ of the genera(ca.2700)of the flora will be barcoded by 2015.
