US 2003/0200569 A1 · Amino acid:glyoxylate aminotransferase genes from plants and uses thereof

Abstract

The present invention provides plant amino acid:glyoxylate aminotransferase genes. Also disclosed are the recombinant production of these plant amino acid:glyoxylate aminotransferase enzymes in heterologous hosts, screening chemicals for herbicidal activity using these recombinantly produced enzymes, and the use of thereby identified herbicidal chemicals to suppress the growth of undesired vegetation. Furthermore, the present invention provides methods for the development of herbicide tolerance in plants, plant tissues, plant seeds, and plant cells using the amino acid:glyoxylate aminotransferase genes of the invention.

Claims16

Dependent claims

A method of selecting a herbicidal compound, comprising:

(a) combining a polypeptide comprising an amino acid sequence at least 90% identical to SEQ ID NO:2 and a compound to be tested for the ability to bind to said polypeptide under conditions conducive to binding;
(b) selecting a compound identified in step (a) that binds to said polypeptide;
(c) applying a compound selected in step (b) to a plant to test for herbicidal activity;
and
(d) selecting a compound identified in step (c) that has herbicidal activity.
