function: restoring fertility; transgenic RF3 plants contain the barstar gene to restore fertility in the hybrid line. The gene codes for a ribonuclease inhibitor (barstar), which specifically inhibits the barnase expressed by the MS8 line.
As a result, when pollen from the restorer line RF3 is crossed to the male sterile line MS8, the resultant progeny are able to develop normal anthers and pollen. |
