Progress in the Study and Application of Aphid-resistant Genes
抗蚜基因及其转基因植物的研究进展

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.
