Use of Phosphinothricin-containing Herbicides in Agriculture and Horticulture

Further registered applications of glufosinate-ammonium cover its use as harvest aid [19], especially for pre-harvest leaf and vine desiccation in potatoes [41]. 

1 Genetic Approaches to generate Glufbsinate-Selectivity in Crops Target-based Approaches 

In parallel, attempts were made to mutate the alfalfa GS c-DNA. Even though it was possible to complement a GS deficient E. coli mutant by the alfalfa GSi cDNA [45], all attempts to generate in the E. coli system glufosinate tolerant GSi mutants failed. The few mutants that showed a reduced binding affinity for glufosinate lost their binding affinity for glutamate as well.
