Abstract: Biomass energy is an important renewable energy source and Miscanthus is considered as one of the most promising biomass energy crops. The research has been funded in the European Union and America for Miscanthus, especially the triploid species Miscanthus×Giganteus. The application of cell engineering in improving Miscanthus as a dedicated bioenergy crop is summarized as follows: 1) Studies of in vitro regeneration systems for Miscanthus, focusing on callus induction and differentiation or shoot proliferation, in which the main factors influencing regeneration efficiency were evaluated, including hormones, explants, supplementary additions, medium compositions, different carbon sources and their sterilization methods; 2) Studies of chromosome ploidy manipulation for Miscanthus, mostly for in vitro chromosome doubling of Miscanthus but one for haploid breeding. At the end of this paper the developing trends of cell engineering for the energy crop Miscanthus are briefly discussed.
