抗蚜基因及其转基因植物的研究进展

在我国目前的环境条件下，蚜虫作为农业害虫和植物病毒的传播者，已经成为严重威胁农业生产发展重要的害虫之一。抗蚜植物基因工程可以有效抑制蚜虫危害，并且随着对生命科学的深入理解和技术手段的日益成熟，得到广泛的关注和重视。抗蚜植物基因工程的核心是抗蚜基因的筛选、转抗蚜基因植物的培育以及生物安全性。本文讨论了多种抗蚜基因，并重点论述雪花莲凝集素和苋菜凝集素基因在目前科学研究和生产实践的应用。

Progress in the Study and Application of Aphid-resistant Genes

Aphids have been one of the most serious threatens to China's agriculture, being responsible for the direct damage to crop and the transmission of plant viruses under the present environment. With the in-depth understanding of life science and the development of transgenic technology, genetic engineering in developing aphid-resistant plants has already had attention and been proven to be an effective way to resolve the problems caused by aphid pests. The progress is depending on the characterization of genes which have high toxicity or inhibition activity to aphids and the culture of aphid-resistant transgenic plants. This review describes the research on aphid-resistant genes used in current study and application, and will focus on the expression of Galanthus nivalis Agglutinin gene and Amaranthus caudatus agglutinin gene in transgenic plants and their aphid-resistant effects.
