The present inventors have discovered that 3-oxo-5-alpha-steroid 4-dehydrogenase (DET2) is essential for plant growth. Specifically, the inhibition of DET2 gene expression in plant seedlings resulted in seedlings that are shorter than controls and chlorotic. Thus, DET2 can be used as a target for the identification of herbicides. Accordingly, the present invention provides methods for the identification of compounds that inhibit DET2 expression or activity, comprising: contacting a compound with a DET2 and detecting the presence and/or absence of binding between said compound and said DET2, or detecting a decrease in DET2 expression or activity. The methods of the invention are useful for the identification of herbicides. |
