Isolated dna molecule expression vector process of using the transgenic plant expression vector male-sterile plant production process process of using a specific carpet-regulatory element

摘要

A novel DNA regulatory element that confers anther tapetum-specific gene expression has been discovered, isolated, and characterized. The tapetum-specific regulatory element can be used to control the expression of a foreign gene that disrupts the function of tapetal cells. Thus, the control of maize pollen production can be achieved by using the tapetum-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.
