Title: Inhibition of plant cell respiration
Inventor: BRIDGES IAN G
IPC: C07K14/415
Filed: 1990-01-26
Abstract: INHIBITION OF PLANT CELL RESPIRATION                       ABSTRACT     1.  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.
