植物纤维素合成酶基因和纤维素的生物合成

Cellulose Synthase Gene and Cellulose Biosynthesis in Plants

纤维素地球上最丰富的生物大分子和最重要的可再生资源,1996年克隆了第一个植物纤维素合成酶基因,植物纤维素的生物合成需要多个纤维素合成酶与其他相关酶如Korrigan纤维素酶,蔗糖合成酶等来共同完成。本文介绍了植物纤维素合成酶基因和纤维素的生物合成途径及其相关基因如蔗糖合成酶基因、KORRIG-AN基因等研究进展。

Cellulose,a crystalline β-1,4-glucan, is the world＇s most abundant biopolymer and renewable energy source. Genes for cellulose biosynthesis in plants were isolated in 1996. Many cellulose synthases and other proteins such as Korrigan endocellulase, sucrose synthase had proved to be involved Cellulose biosynthesis in plants,This paper reviews the current achievements in the field of gene cloning and function studies of plant cellulose synthase gene and a pathway of cellulose biosynthesis in plants.
