Application Notes
DL-phosphinothricin is also known as glufosinate-ammonium (GLA) and is an active ingredient in Basta®. It functions by inhibiting the glutamine synthase in the chloroplast from synthesizing glutamine to glutamate, which causes ammonia accumulation, thus results in plant death.2, 3, 4

Typical working concentration of GLA varies by applications. It has been reported that treatment of GLA at 0.5 µg/mL stimulates the somatic embryo formation of Vitis interspecific hybrid2 , while GLA concentrations range from 50 µg/mL to 400 µg/mL are used in the transformation of Magnaporthe grisea3

PhytoTechnology Laboratories® also carries DL-Phosphinothricin solution at 1 mg/mL, Product No. G523.
