METHODS OF USING 3-HYDROXY-3-METHYLGLUTARYL-COA SYNTHASE TO ENHANCE GROWTH AND/OR SEED YIELD OF GENETICALLY MODIFIED PLANTS

Provided herein is a transgenic plant, seed, or progeny, genetically engineered to overexpress one or more exogenous 3-hydroxy-3-methylglutaryl-CoA synthase 1 (HMGS1) in an amount effective to enhance growth and/or seed yield relative to a control plant. Also provided are methods of enhancing plant growth and/or seed yield by genetically engineering a plant to overexpress one or more exogenous HMGS1 in an amount effective to enhance growth and/or seed yield relative to a control plant. The plant belongs to the Solanaceae family, and the one or more exogenous HMGS1 comprise an amino acid sequence at least 77% identical to Brassica juncea HMGS1 as set forth in SEQ ID NO:6. Further provided are methods of screening for a functional variant of Brassica juncea HMGS1.published_or_final_versio
