Phosphinothricin-acetyl-transferase PAT

Glufosinate or phosphinothricin (libeirty and Basta ) inhibits glutamine synthetase that results in the toxic build-up of ammonia in plant cells. LL cotton, commercialized in 2004, was achieved via detoxification by phosphinothricin acetyl transferase (PAT). LL cotton grew from 1 to 3% of the total cotton acres in 2005 (Fig. 6.1.3).
