摘要
纤维素是植物细胞壁的主要成分。自然界中每年大约有 180 0亿吨的纤维素产物生成。纤维素的巨大经济价值使纤维素合成酶基因成为基因工程的热点之一。 1996年 ,Delmer小组首次从植物中克隆出纤维素合成酶基因。近年来 ,在纤维素合成酶的结构、功能、定位和基因功能的研究方面成果斐然。
Cellulose is a major component in plant cell wall.About 180 billion tons of cellulose are produced per year in nature.The commercial importance of cellulose makes the genes coding it one of attractive targets for plant genetic engineering.A number of cellulose synthase genes have been first cloned from plant species by Delmer's group in 1996.Recently,research achievement has been obtained in accumulating to understanding the cellulose synthase function,location,and the gene function.The paper summarized the research progress of cellulose synthase genes in higher plants.
