Wheat varieties and leaf rust samples of Hebei province were collected in 1982 and study of interaction between host and pathogen was made in 1983. The results expressed by virulence frequency showed that this method of investigation provided directly the information of the interrelationship between the wheat varieties and the rust fungus .

我科研组采取毒力频率来研究河北省小麦品种和河北省叶锈菌的相互作用，我们认为：这种研究方法能直接反应品种与菌株之间相互作用的情况，对生产者和抗病育种工作者提供的信息，要比小麦叶锈菌小种鉴定提供的以编号对小种命名的小种名单要有用得多。

Resistance responses were studied in different Arabidopsis ecotypes after being inoculated by some important plant pathogens. According to the results, molecular mechanisms of resistance and expression of the defense-related genes in resistance and susceptible Arabidopsis ecotypes were studied. Results followed in this paper.All the 11 Arabidopsis ecotypes tested were incompatible to Erysiphe convolvuli, Alternaria brassicicola, Setosphaeria turcica and Verticillium dahliae.
