摘要
木质素是植物体内仅次于纤维素的一类重要的大分子有机物,具有支持、保护和运输等重要的生物学功能,木质素的生物合成是植物从水生到陆生进化的一种适应。然而,木质素的存在对植物资源的利用有一些不利影响,主要体现在导致造纸污染严重及影响牲畜对饲草的消化和吸收等方面。通过基因工程手段调控木质素的生物合成具有重大的环保价值和经济价值。介绍了近年来研究的木质素生物合成途径,重点综述了调控木质素生物合成的最新研究进展,提出存在的问题并预期今后的发展。
Lignin is a kind of important macromolecular organic material and only inferior to cellulose inside plant with important biology functions like sustaining, protecting, transporting and so on. The ability to synthesize lignin has been essential in the evolutionary adaptation of plants from an aquatic environment to land. Whereas the lignin has negative effect on utilizing the plant resource in some areas, such as resulting in severe environmental pollution in the paper making and reducing the digestibility of silage grass. Regulating of lignin content through gene engineering plays important roles in environment protection and economy. The progress of recent research on the liguin biosynthesis is introduced. The hot area of the new progress of regulation of lignin content was presented. Meanwhile, some problems needed to research are suggested and the possible developments from now on are forecasted.
