 Miscanthus plants used as an alternative biofuel material: The basic studies on ecology and molecular evolutionChang-Hung Chou Renewable Energy, 2009, vol. 34, issue 8, 1908-1912 Abstract: Miscanthus Anderss, widely distributed in Asia and Pacific Islands, possesses 20 species. Of which 8 species and 1 variety were recorded in Chinese Mainland; 6 species and 1 variety found in Japan; 5 species and 3 varieties distributed in Taiwan; 3 species documented in the Philippines; and rest of species have been recorded in Jawa, eastern Himalaya, and Sikkim. The plant is a C4 perennial grass with high productivity of biomass. In the 19th and early 20th centuries in Taiwan, Miscanthus was a very important crop used for forage grass, clothing, and shelter, etc. The relatively high germination, and high yield of biomass made the plant available for people of Taiwan including aboriginal. The taxonomic study of Miscanthus plants was much done by several scientists, and its ecological study has been only taken by the present author since 1972. Chou and his associates paid a great attention to elucidate the mechanism of dominance of Miscanthus vegetation and found that allelopathy plays an important role. In addition, the population biology of Miscanthus taxa by using polyacrylamide gel electrophoreses technique to examine the patterns of peroxidase and esterase among populations (over 100) of Miscanthus in Taiwan were conducted. They also elucidated the phylogenetic relationship among species and varieties in Taiwan. Chou and Ueng proposed an evolutionary trend of Miscanthus species, indicating that the Miscanthus sinensis was assumed to be the origin of Miscanthus Anderss, which evolved to M. sinensis var. formosana, and M. sinensis var. flavidus, and M. sinensis var. transmorrisonensis, and Miscanthus floridulus was thought to be an out group of M. sinensis complex. Moreover, molecular phylogeny was attempted to clarify the population heterogeneity of M. sinensis complex, resulting in a substantial information. It would be available for making hybridization between Miscanthus species and its related species, such as Saccharum (sugar cane) spp. which is a high energy resource plant. European scientists already brought Asian Miscanthus species and bred a new hybrid called Miscanthus×giganteus, which is now being used as a biofuel material in Europe and would be widely used in the world in the near future if fundamental questions, such as fiber transformation to alcohol or other breeding techniques, are answered.
