Embodiment Construction

[0234] It has now surprisingly been found that modulating expression in plants of a nucleic acid encoding an alfin-like polypeptide gives plants having increased tolerance to abiotic stress relative to control plants. According to a first embodiment, the present invention provides a method for enhancing the tolerance of a plant to various abiotic stresses relative to control plants, comprising regulating expression in a plant of a nucleic acid encoding an alfin-like polypeptide and optionally selecting a plant with Plants with enhanced tolerance to abiotic stress.

[0235]Furthermore, it has now surprisingly been found that modulating expression in plants of a nucleic acid encoding a YRP polypeptide can give plants having increased tolerance to abiotic stress relative to control plants. According to a first embodiment, the present invention provides a method for enhancing the tolerance of a plant to a variety of abiotic stresses relative to control plants, comprising regulatin...

Abstract

The present invention relates generally to the field of molecular biology and relates to methods for enhancing various plant yield-related traits by increasing expression in plants of nucleic acid sequences encoding Brevis Radix-like (BRXL) polypeptides. The present invention also relates to plants having increased expression of a nucleic acid sequence encoding a BRXL polypeptide, said plants having enhanced yield-related traits relative to control plants. The invention also relates to nucleic acid sequences, nucleic acid constructs, vectors and plants comprising said nucleic acid sequences.

Description

technical field [0001] The present invention relates generally to the field of molecular biology and relates to methods of enhancing abiotic stress tolerance by modulating expression in plants of nucleic acids encoding alfin-like polypeptides. The present invention also relates to plants having modulated expression of an alfin-like polypeptide-encoding nucleic acid, which plants have enhanced abiotic stress tolerance relative to corresponding wild-type plants or other control plants. The invention also provides constructs that 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 abiotic stress tolerance in plants by modulating the expression in plants of a nucleic acid encoding YRP. The present invention also relates to plants having modulated expression of a YRP-encoding nucleic acid, which plants have enhanced abiotic stress tolerance relati...
