Phosphinothricin resistance
Glufosinate (also known as phosphinothricin and often sold as an ammonium salt) is a naturally occurring broad-spectrum herbicide produced by several species of Streptomyces soil bacteria. Glufosinate is a non-selective, contact herbicide, with some systemic action. Plants may also metabolize bialaphos and … See more In the 1960s and early 1970s, scientists at University of Tübingen and at the Meiji Seika Kaisha Company independently discovered that species of Streptomyces bacteria produce a tripeptide they called bialaphos that … See more Phosphinothricin is a glutamine synthetase inhibitor that binds to the glutamate site. Glufosinate-treated plants die due to a buildup of ammonia in the thylakoid lumen, leading to the uncoupling of photophosphorylation. The uncoupling of photophosphorylation … See more Glufosinate is a United States Environmental Protection Agency EPA registered chemical. It is also a California registered chemical. … See more Glufosinate is a broad-spectrum herbicide that is used to control important weeds such as morning glories, hemp sesbania (Sesbania bispinosa), Pennsylvania smartweed ( See more Exposure to humans in foods As glufosinate is often used as a pre-harvest desiccant, residues can also be found in foods that humans ingest.

WebPhosphinothricin (PPT) is a potent inhibitor of glutamine synthetase in plants and is used as a non-selective herbicide. The bar gene which confers resistance in Streptomyces hygroscopicus to bialaphos, a tripeptide containing PPT, encodes a phosphinothricin acetyltransferase (PAT) (see accompanying paper). WebThe present invention relates to specific herbicide combinations comprising (i) L-glufosinate and/or salts thereof and (ii) carfentrazone-ethyl in specific ratios, and to compositions comprising said herbicide combinations in these ratios.
