How the abundant tree biomass resources can be efficiently used for future biofuel production has attracted a great deal of interest and discussion in the past few years. Capable technologies are expected to be developed to realize the production of biofuel from wood biomass. A significant effort is put into the field of modifying wood properties of trees and simplifying the process of biomass-to-ethanol conversion, which includes mainly genetic engineering of lignin, cellulose and hemicellulose of woods. Current research in this field has achieved some promising results and opened up new opportunities to utilize wood biomass efficiently. This review will discuss the main developments in genetic modification of lignin, cellulose and hemicellulose biosynthesis in trees as well as other potential genetic technology of biofuel production from wood biomass.
在过去几年里，如何有效利用丰富的树木生物质资源用于未来生物燃料生产引起了广泛关注和讨论。人们期望开发出可行的技术来实现从木材生物质生产生物燃料。在改变树木木材特性以及简化生物质到乙醇转化过程的领域投入了大量努力，这主要包括对木材中木质素、纤维素和半纤维素的基因工程改造。该领域目前的研究已取得一些有前景的成果，并为高效利用木材生物质开辟了新机遇。本综述将讨论树木中木质素、纤维素和半纤维素生物合成基因改造的主要进展以及从木材生物质生产生物燃料的其他潜在基因技术。
