摘要: 果聚糖是一类重要的可溶性碳水化合物,其在植物中的积累可提高植物的抗逆性。本文除了介绍果聚糖的有关知识外,重点综述了果聚糖对植物抗逆性的影响,并从果聚糖对渗透的调节,对膜的保护,在低温、干旱条件下果聚糖相关酶活性变化方面阐述了果聚糖抗旱、抗寒机制。此外,综述了提高果聚糖积累方面的基因工程研究进展及存在的相关问题。

Abstract: Fructan is a very important water soluble carbohydrate. The fructan accumulation in plants can improve stress resistance. This paper introduced some knowledge of fructan and reviewed the effect of fructan on plants' stress tolerance. Some mechanism of freezing tolerance or drought tolerance were expatiated at fructan and osmotic adjustment, fructan and membrane and fructosyltansferase activity. In addition, the gene engineering of improving fructan accumulation and correlated quest ion were reviewed.

Key words: Fructan, Stress resistance, Fructosyltansferase, Adjustment, Gene engineering
