ABSTRACT:
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.
