Two bifunctional streptomyces - e . coli vectors were constructed that contained the phage lambda promoter ( pr ) upstream of the his6 - tagged recombinant pks gene 构建了两个链霉菌-大肠杆菌双功能pks表达质粒，在重组pks基因上游携带有噬菌体启动子。
We have studied the involvement of signal transduction in the regulation of antibiotic biosynthesis , and the genetics and biochemistry of drug efflux in streptomyces 我们也研究讯号传导系统参与的抗生素合成的调控，以及链?菌抗药性的遗传与生化机转。
The disease is usually caused by a bacterium , e . g . common scab of potatoes ( streptomyces scabies ) , or a fungus , e . g . apple scab ( venturia inaequalis ) 此种疾病通常由细菌或真菌引起，例如土豆的疮痂（由疥疮链霉菌引起） ，和苹果黑星病（由不等黑星菌引起） 。
The sequences difference between other species was on genus level . so it maybe a new genus . strain 10035 belonged to streptomyces 菌株10035属于链霉菌属( streptomyces ) ，与其关系最近的菌株streptomycesyunnanensis16srdna序列相似性为97 . 54 ，可能是新种。
It was demonstrated that the pcr - mediated method to detect the chitinase - producing streptomyces from soil environment is possible and effective , and the primers designed are also qualified 在分子探测基础上，对其中一株链霉菌s93的几丁质酶基因进行了克隆。
Abstract : the efficacy of 1368 streptomyces isolates for controlling cucumber seedling blight diseases caused by phytophthora melons kalsura were screened and evaluated in greenhouse 文摘:应用防治黄瓜苗期疫病生物测定法对分离获得的1368个放线菌菌株进行初步筛选。
In this paper , the homology of transport proteins of streptomyces lydicus and other actionmycetales bacteria is analysed and their evolutional relation is discussed 将获得的利迪链霉菌的转运蛋白基因与其他放线菌的转运蛋白基因进行了同源性分析，探讨了基因的进化关系。
A signal transduction via not only two - component regulatory system but also serine / threonine kinases generally regulates morphological and physiological differentiation in streptomyces 途经双元件调控系统和丝氨酸苏氨酸蛋白激酶的信号传导调控链霉菌的形态和生理分化。
The transformants were cultivated and the harvested cells were used in the procedure of conjugation by which the recombinant plasmid pid03 and pc05 were introduced into streptomyces avermitilis s - 2 respectively 经过在mym平板上的传代和抗性标记的筛选分别得到了同源双交换的菌株aved24和avecg 。
