The conversion of plant biomass into liquid transportation fuels is a complex process that could be simplified by altering the ratios of the cell wall polymers that constitute the main biomass components. The composition of biomass varies naturally depending upon plant species and cell type, including some highly specialized walls that consist mainly of a single component. Progress is being made in understanding the molecular basis of these natural variations in wall composition. This new knowledge will be a valuable resource that can be used during efforts to generate designer biofuel crops using either selected breeding methods or recombinant DNA techniques.
将植物生物质转化为液体运输燃料是一个复杂的过程，可以通过改变构成主要生物质成分的细胞壁聚合物的比例来简化这个过程。生物质的组成会根据植物种类和细胞类型而自然变化，包括一些主要由单一成分组成的高度特化的细胞壁。人们在理解细胞壁组成的这些自然变化的分子基础方面正在取得进展。这些新知识将成为一种有价值的资源，可以用于利用有性选择或重组 DNA 技术来生成设计生物燃料作物的努力。
