马铃薯抗晚疫病转基因的研究进展

Progress on Gene Engeneering in Late Blight Disease of Potato

晚疫病是影响马铃薯最严重的一种真菌性病害,农业技术的综合应用、化学药剂的使用对晚疫病的防治存在种种弊端。因此,寻找新的抗病基因型,获得抗晚疫病的转基因新品种一直是马铃薯抗晚疫病的主要任务。本文简要介绍了马铃薯晚疫病的危害及防治,着重对从Osmotin蛋白诱导抗性、病原诱导葡萄糖氧化酶(GO)基因表达生成H2O2获得抗性、Harpin蛋白基因表达诱导抗性途径对马铃薯抗晚疫病转基因研究进展进行了综述,同时对转基因植物的生物安全性作了评价。

Late blight disease is one of the most serious fiangal diseases in potato plants. But the present agricultural technology and chemical materials have lead to many malpractices in the prevention of this disease. Therefore, cloning of the diseaseresistant genes and the establishment of resistant cultivars, have been the primary tasks in the prevention of potato late blight disease. In this study, we review the harmful effects and preventive ways of the late blight disease in potato plants. The study focuses on osmotin protein induced-resistance, Glucose oxidase （GO） derived H2O2 induced-resistance and hairpin protein induced-resistance. The security provided by transgertic plants is also evaluated.
