植物与微生物之间的亲和性是研究植物与微生物相互关系的重要内容。本文采用标记基因法,将外源抗性基因引入分离自棉花植株中的一个假单胞菌(Pseudomonas spp.)菌株B_4中,获得Kmr和Rifr的双重抗性株。利用抗性基因标记法,研究了B_4与棉花幼苗的亲和性,取得比较满意的结果。
Affinity between plants and microorganisms is an important part of studying the relationship between plants and microorganisms. In this study, we used marker gene method to introduce exogenous resistance genes into a Pseudomonas spp. Strain B_4 isolated from cotton plants and obtained double resistant strains of Kmr and Rifr. The resistance of B_4 to cotton seedlings was studied by using resistance gene marker method, and the satisfactory results were obtained.
