According to the crucial enzymes involved in the synthesis of sucrose, starch and lipid, various combinations of crucial enzymes were used to retrieval in NCBI （the National Center for Biotechnology Information） database to screen out species with high similarities. Moreover, comprehensive evaluation formulas were designed to excavate potential biofuel plants, which considered several parameters including the homology index, availability rate, distribution area in China, price index and function index. Finally, tens of superior plant species, for example, Panicum virgatum, Zeal luxuriant and Brassica napus, are suggested to be the potentials in future biofuels productions. These plants have the characteristics of wide distribution, high yield, and low cost in production, and they are useful for environmental protection as well as sources of non-crop biomass fuels in China. The results provide a theoretical basis for further study and exploitation of biofuels.展开更多
