The rubber tree Hevea brasiliensis is the almost exclusive commercial source of natural rubber but cannot meet the growing global demands for rubber because of restricted cultivation. More- over, South American leaf blight is a potential risk to decimate tress in terms of production. Plants of rubber-producing Taraxacum, producing high-molecular-weight NR, are fast-growing, widely adaptable and easily harvested and so con- sidered a promising altemative rubber source. We review advances in study of rubber-producing Taraxacum, including germplasm resources and breeding, agronomic techniques, and the biological mechanism of NR biosynthesis. The hot- spots and key issues are discussed to propose study of rubber-producing Taraxacum and to provide references for this research in China Key words natural rubber, Taraxacum koksaghyz, T. brevicorniculatum, germplasm resources, biosynthesis Qiu J, Zhang JC, Luo sQ, Xiao XZ, Wang F, Zhang LQ, Liu SZ(2015).
