Abstract: Alfalfa (Medicago sativa L.) has been recognized as one of the potential biofuel crops with high biomass and wild adaptability. Most importantly, the stems of alfalfa would be processed to produce ethanol and the leaves could be served separately as a livestock feed. In this paper, the recent advances of the studies and utilization of alfalfa as energy plant were reviewed, which including germplasm evaluations of biofuel traits, development of stem cell wall, biosynthetic pathways and genetic control of cell wall components (cellulose, hemi-cellulose and lignin), and the effects of cultivation management system to ethanol production. The development of stem cell wall and genetic regulation of lignin in alfalfa were discussed. Furthermore, the perspective utilization of alfalfa as biofuel crop was also proposed.

Key words: alfalfa , bioenergy , energy crop , cell wall , lignin
