摘　　要：果聚糖,是由多种细菌和植物产生的一种果糖聚合物,是重要的存储碳水化合物;菊苣是一种商业果聚糖生产作物。果聚糖在菊苣体内的生物合成是难以控制的。特定果聚糖是原本非果聚糖积累植物引进果糖基转移酶基因的成功表达。较为系统地综述了果聚糖的生物合成及修改、特定果聚糖的合成、果聚糖的功能及应用等方面的研究进展。. Fructan, a fructose polymer,is produced by many bacteria and plants and used as carbohydrate re- serve. Chicory is a commercial fructan producing crop. Studies using genetically modification showed that fruc- tan biosynthesis is difficult to steer in chicory. Alternatives for production of tailor-made fructan,fructan with a desired polymer length and linkage type, are originally nonfructanaccumulating plants expressing introduced fructosyltransferase genes. Fructan biosynthesis and its modification, synthesis of tailor-made fructan,and func- tion and utilization of fructan were briefly reviewed in the article.
