摘要
海藻糖是一种非还原性双糖,具有很高的稳定性和很强的吸水性等性质,能够提高生物体对各种非生物胁迫的抵抗能力。目前有很多研究表明通过转化海藻糖合酶基因增加体内海藻糖含量可能成为选育作物抗逆品种的新方法。该文对海藻糖的理化性质、生物学特性及其应用情况作了简要的概述,并介绍了编码酵母海藻糖合酶复合体基因的组成以及各个组成基因的功能,着重阐述了海藻糖合酶基因在植物转基因方面(尤其在提高植物抗逆性)的研究进展。
Trehalose is a non-reducing disaccharide, and it has particular physical and chemical features （high stability and strong water absorption）, so trehalose is able to protect the organism against a variety of abiotic stresses. Many researches have shown that increasing the trehalose content through genetic transforming of plants with trehalose synthase gene, creates a new method of breeding crops tolerant to variety stresses. The physical and chemical properties and the bio-function of trehalose were summarized in this paper, and the composition and function of the Saccharomyces cerevisiae trehalose synthase complex gene were introduced. Moreover, the application of trehalose synthase gene in transgenic plants （especially in stress tolerance of plant） was expatiated.
