PLANTS HAVING ENHANCED YIELD-RELATED TRAITS AND A METHOD FORMAKING THE SAME

摘要

The present invention relates generally to the field of molecular biology and concerns a method for enhancing various economically important yield-re lated traits in plants. More specifically, the present invention concerns a method for enhancing yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding a Yield Enhancing Protein (YEP). The YEP is selected from a Vacuolar Processing Enzyme (VPE) or a CCA1-like polyp eptide ora SAP-like polypeptide or a Seed Yield Promoting Factor 1 (SYPF1) p olypeptide ora Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) act ivase (RCA) polypeptide. The present invention also concerns plants having m odulated expression of a nucleic acid encoding such a YEP, which plants have enhanced yield-related traits relative to control plants. The invention als o provides hitherto unknown YEP-encoding nucleic acids, and constructs compr ising the same, useful in performing the methods of the invention.
