Maize （Zea mays L. ） genic male-sterile mutant has been widely studied for its biological significance on pollen developmental study and commercial value in hybrid vigor utilization. As the development of molecular biotechnology, several genie male-sterile genes has been cloned and characterized in maize, leading to potential use of genetic engineering male-sterility in commercial hybrid seed production. Here, the progress of cytological characterization, gene cloning and molecular mechanism of genie male-sterility study in maize are reviewe,...
