Problems solved by technology

However, artificial limitations on yield due to poor pollination (caused by lack of wind or insects) or insufficient space for mature root or canopy growth, etc., limit the use of these controlled environments for testing yield differences

Embodiment Construction

[0241] It has now surprisingly been found that modulating the expression of a nucleic acid encoding an HSFA4 or HSFA5 polypeptide in plants can produce plants with enhanced yield-related traits relative to control plants. According to the first embodiment, the present invention provides a method for enhancing yield-related traits of plants relative to control plants, comprising modulating the expression in plants of nucleic acids encoding HSFA4 or HSFA5 polypeptides and / or modulating the level and / or activity of HSFA4 protein, and Plants with enhanced yield-related traits are optionally selected.

[0242] In addition, it has now surprisingly been found that modulating the expression of a nucleic acid encoding an OPT4-like polypeptide in a plant can produce plants with enhanced yield-related traits relative to control plants.

[0243] The invention also provides hitherto unknown OPT4-like nucleic acid and polypeptide sequences.

[0244] An isolated nucleic acid molecule is provided, ...

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.

Description

[0001] This application is a divisional application of Chinese patent application 201080014740.0 (PCT / EP2010 / 050310) with the title of "plants with enhanced yield-related traits and preparation methods" on January 13, 2010. Technical field [0002] The present invention generally relates to the field of molecular biology, and relates to methods for enhancing various economically important yield-related traits in plants. More specifically, the present invention relates to methods for enhancing yield-related traits by modulating the expression in plants of nucleic acids encoding HSFA4 or HSFA5 (A4 or A5 heat shock factor) polypeptides. The present invention also relates to plants having regulated expression of a nucleic acid encoding a HSFA4 or HSFA5 polypeptide, which plants have enhanced yield-related traits relative to control plants. The present invention also provides a construct comprising the nucleic acid that can be used to implement the method of the present invention. [0...
