    摘要: T-DNA tagging with a promoterless .beta.-glucuronidase (GUS) gene generated a transgenic Nicotiana tabacum plant that expressed GUS activity constitutively. The gene fusion has been cloned and sequenced. It has been re-inserted into N. tabacum by Agrobacterium-mediated transformation. The N. tabacum DNA upstream from the GUS gene was approximately 2 kb in length and showed no homology to known sequences. This DNA, which contains a constitutive promoter, is useful in controlling the expression of exogenous genes in transgenic plants of diverse plant species.

    摘要: T-DNA tagging with a promoterless β-glucuronidase (GUS) gene generated transgenic Nicotiana tabacum plants that expressed GUS activity either only in developing seed coats, or constitutively. Cloning and deletion analysis of the GUS fusion revealed that the promoter responsible for seed coat specificity was located in the plant DNA proximal to the GUS gene. Analysis of the region demonstrated that the seed coat-specificity of GUS expression in this transgenic plant resulted from T-DNA insertion next to a cryptic promoter. This promoter is useful in controlling the expression of genes to the developing seed coat in plant seeds. Similarly, cloning and characterization of the cryptic constitutive promoter revealed the occurrence of several cryptic regulatory regions. These regions include promoter, negative regulatory elements, transcriptional enhancers, core promoter regions, and translational enhancers and other regulatory elements.

    摘要: A novel DNA regulatory element that confers microspore-specific gene expression has been discovered, isolated, and characterized. The microspore-specific regulatory element can be used to control the expression of a foreign gene that disrupts the function of microspores. Thus, the control of pollen production can be achieved by using the microspore-specific regulatory element to produce male-sterile plants. Various methods can be used to restore male fertility in the F1 generation of such male-sterile plants. In addition, the microspore-specific regulatory element can be used to confer resistance to viral and insect pests.
