Abstract:
1. A method for identifying a substance that modulates plant glutamine synthetase activity in vitro comprising the steps of: (a) contacting a plant glutamine synthetase with a test plant glutamine synthetase modulator that comprises an isolated culture or a whole cell broth of (b) determining whether or not the activity of the glutamine synthetase is modulated relative to the activity of a plant glutamine synthetase that has not been contacted with the test plant glutamine synthetase modulator; (c) comparing the activity of the plant glutamine synthetase when contacted with the test plant glutamine synthetase modulator with the activity of the plant glutamine synthetase when contacted with a known plant glutamine synthetase modulator; (d) applying said test plant glutamine synthetase modulator to at least a portion of a plant; and (e) determining if said test plant glutamine synthetase modulator has herbicidal activity.
