Manipulation Of Lignin Biosynthesis To Maximize Ethanol Production From Populus Feedstocks

[摘要] Our research focuses on transgenic strategies for modifying lignification to improve biomass quality, without leading to deleterious effects on plant performance. In order to accomplish this objective, we designed molecular strategies and selected appropriate transgenes for manipulating the expression of lignification-associated genes; we generated poplar engineered for altered lignin content and/or monomer composition, and field-tested them for fitness; we analyzed the impact of these transgenic strategies on metabolism in general and lignin biosynthesis in particular; and evaluated the ease with which cell wall deconstruction can be accomplished using both chemical and enzymatic means using wild-type and high syringyl poplar.
