Abstract
Cupric sulfate induced mRNA specific to the copper resistance gene cluster previously cloned from Pseudomonas syringae pv. tomato PT23. mRNA from each of the four genes of this cluster responded in a similar manner to induction over time and with different concentrations of cupric sulfate. Promoter fusion constructs indicated the presence of a single copper-inducible promoter upstream from the first open reading frame.
摘要
硫酸铜诱导出了与先前从丁香假单胞菌番茄致病变种PT23克隆出的铜抗性基因簇特异的信使核糖核酸。该基因簇四个基因中的每一个基因的信使核糖核酸，对随着时间推移以及不同浓度硫酸铜的诱导，都有相似的反应。启动子融合构建体表明在第一个开放阅读框上游存在一个单一的铜诱导型启动子。
