<p>A variety of genes may be used to express protein which inhibits full expression of selected characteristics of plants. These inhibit functions which are critical to full expression of a genetic characteristic. Also known as 'killer' genes, a particular area of interest is in the expression of a protein inhibitor of mitochondrial function leading to cell death and failure to produce viable pollen, thus imparting male sterility. When inserted as a module in a gene cascade which permits external control of expression, male fertility may be restored.</p> |
