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

摘要

Plants having enhanced yield-related traits and a method for making the same The present invention relates generally to the field of molecular biology and concerns a method for enhancing various economically important yield-related 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 HSFA4 or HSFA5 (Heat Shock Factor of the class A4 or A5) polypeptide. The present invention also concerns plants having modulated expression of a nucleic acid encoding a HSFA4 or a HSFA5 polypeptide, which plants have enhanced yield-related traits relative to control plants. The invention also provides constructs comprising the same, useful in performing the methods of the invention. Furthermore, the present invention relates generally to the field of molecular biology and concerns a method for enhancing various yield-related traits by modulating expression in a plant of a nucleic acid encoding an oligopeptide transporter protein (OPT4-like) polypeptide. The present invention also concerns plants having modulated expression of a nucleic acid encoding an OPT4-like polypeptide, which plants have enhanced yield-related traits relative to corresponding wild type plants or other control plants. The invention also provides constructs useful in the methods of the invention. The invention also provides hitherto unknown OPT4-like-encoding nucleic acids, and constructs comprising the same, useful in performing the methods of the invention. Furthermore, the present invention relates generally to the field of molecular biology and concerns a method for enhancing various yield-related traits by modulating expression in a plant of a nucleic acid encoding a plastochron2-like (PLA2-like) polypeptide. The present invention also concerns plants having modulated expression of a nucleic acid encoding a PLA2-like polypeptide, which plants have enhanced yield-related traits relative to corresponding wild type plants or other control plants. The invention also provides constructs useful in the methods of the invention. Furthermore, the present invention relates generally to the field of molecular biology and concerns a method for enhancing yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding a Wuschel related homeobox 1 -like (W0X1 -like) polypeptide. The present invention also concerns plants having modulated expression of a nucleic acid encoding a W0X1 -like polypeptide, which plants have enhanced yield-related traits relative to corresponding wild type plants or other control plants. The invention also provides constructs useful in the methods of the invention.
