The preparation and use of nucleic acid promoter fragments derived from several genes from corn, petunia and tobacco which are highly responsive to a number of substituted benzenesulfonamides and related compounds are described. These promoter fragments are useful in creating recombinant DNA constructions comprising nucleic acid sequences encoding any desired gene product operably linked to such promoter fragments which can be utilized to transform plants and bring the expression of the gene product under external chemical control in various tissues of monocotyledonous and dicotyledonous plant.
本文描述了从玉米、矮牵牛和烟草的几个基因中提取的核酸启动子片段的制备和使用方法,这些基因对一些取代的苯磺酰胺类化合物和相关化合物有很强的反应性。这些启动子片段可用于创建重组 DNA 结构,该结构包含编码任何所需基因产物的核酸序列,可与这些启动子片段操作性连接,从而可用于转化植物,并在单子叶和双子叶植物的各种组织中使基因产物的表达受到外部化学控制。
