Embodiment Construction

[0240]It has now surprisingly been found that modulating expression in plants of a nucleic acid encoding a HSFA4 or HSFA5 polypeptide gives plants having enhanced yield-related traits relative to control plants. According to a first embodiment, the present invention provides a method for enhancing the yield-related traits of a plant relative to a control plant, comprising regulating expression in a plant of a nucleic acid encoding a HSFA4 or HSFA5 polypeptide and / or regulating the level and / or activity of the HSFA4 protein and Plants are optionally selected for enhanced yield-related traits.

[0241] Furthermore, it has now surprisingly been found that modulating expression in plants of a nucleic acid encoding an OPT4-like polypeptide gives plants having enhanced yield-related traits relative to control plants.

[0242] The present invention also provides heretofore unknown OPT4-like nucleic acid and polypeptide sequences.

[0243] Provided are isolated nucleic acid molecules...

Abstract

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.

Description

technical field [0001] The present invention relates generally to the field of molecular biology and relates to methods of enhancing various economically important yield-related traits in plants. More specifically, the present invention relates to a method for enhancing yield-related traits by modulating expression in plants of a nucleic acid encoding a HSFA4 or HSFA5 (heat shock factor of class A4 or A5) polypeptide. The present invention also relates to plants having modulated expression of a nucleic acid encoding a HSFA4 or HSFA5 polypeptide, which plants have enhanced yield-related traits relative to control plants. The invention also provides constructs comprising said nucleic acid which can be used to practice the methods of the invention. [0002] Furthermore, the present invention relates generally to the field of molecular biology and relates to methods for enhancing various yield-related traits by modulating expression in plants of nucleic acids encoding oligopeptid...
