The present invention discloses methods to screen chemicals for herbicidal activity using recombinantly produced enzymes having HMP-P kinase activity or TMP-PPase activity, and the use of thereby to identify 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 genes encoding enzymes having HMP-P kinase activity or TMP-PPase activity, and methods of using such transgenic plants to selectively suppress weed growth in crop fields. |
