植物凝集素在抗刺吸式害虫转基因工程中的应用

Application of plant lectins in sucking pest-resistant genetic engineering

植物凝集素是一类具有高度特异性糖结合活性的蛋白,含有1个或多个可与单糖或寡聚糖特异可逆结合的非催化结构域,在农业生产上应用前景广阔。本文简要概述了几种植物凝集素:雪莲凝集素、天南星科植物凝集素、苋菜类植物凝集素在抗刺吸害虫基因工程上的应用,并简单介绍了转双价抗虫基因方面的研究。

Plant lectins are proteins possessing at least one non-catalytic domain that binds reversibly to specific mono-or oligosaccharides. They distinguish themselves from other plant proteins by the ability of carbohydrate binding. It has a prospective use in agricultural production. The applications of several plant lectins, i. e. galan- thus nivalis agglutinin, agglutinin from Araceae and agglutinin from Amaranthus on the sucking pest-resistant gene engineering were summarized in this paper. The research on the binary insect-resistant transgenic plant was also introduced.
