Basic Genetic Modification
| Gene Introduced | Gene Source | Product | Function |
| bar | Streptomyces hygroscopicus | phosphinothricin N-acetyltransferase (PAT) enzyme | eliminates herbicidal activity of glufosinate (phosphinothricin) herbicides by acetylation |
| barnase | Bacillus amyloliquefaciens | barnase ribonuclease (RNAse) enzyme | causes male sterility by interfering with RNA production in the tapetum cells of the anther |
| barstar | Bacillus amyloliquefaciens | barnase ribonuclease inhibitor | restores fertility by repressing the inhibitory effect of barnase on tapetum cells of the anther |

Regulatory and Biosafety Information
The GM Approval Database, or GMAD, is one of ISAAA’s unique features that compiles all the available information about biotech/GM crops that have been approved for planting and importation for food and feed, and commercialization. ISAAA sources out the information from publicly available decision documents per country, Biosafety Clearing Houses and peer-reviewed scholarly articles to maintain the credibility of the database. Your contribution can help expand and maintain the GMAD and make useful information more available to researchers, students, and the general public. You can help by donating as little as $10.
