The present invention relates to a method of improving stress tolerance and/or preventing growth reduction of a plant by introducing a polynucleotide encoding a Repetitive Proline-rich Protein (RePRP) into the plant.

Method for improving stress tolerance of plants

The present disclosure relates to transgenic plants that over-express PP2CABA and methods of using such for enhancing osmotic stress tolerance.

Transgenic plants expressing type 2C protein phosphatase abscisic acid (PP2CABA) proteins and uses thereof

The present invention relates to a method for enhancing root growth of a plant by introducing a polynucleotide encoding late embryogenesis abundant protein, group 3 (LEA3) into the plant. Plant root architecture is essential for its functions in water and nutrient uptake, anchorage and interactions with microbes in the soil.

Methods for enhancing root growth of plants

The present invention relates to mutant gibberellin 2-oxidase (GA2ox) genes and uses thereof. In particular, the effective mutations disclosed herein can reduce GA2ox enzymatic activity to different extents, leading to various degrees of GA deficient yet beneficial agronomic traits in transgenic plants.

Mutant gibberellin 2-oxidase genes and uses thereof

A method of making a transgenic plant by transforming into a host plant a recombinant DNA construct that expresses in the transgenic plant a rice polypeptide and the transgenic plant thus produced.

Use of rice polypeptides for the enhancement of grain size

Novel gibberellin 2-oxidase (GA2ox) genes were identified. Differential expression of GA2ox genes correlated with flower development, seed germination, tiller growth and other developmental processes. In addition, the early and increased growth of tiller and adventitious root and altered root architecture caused by overexpression of GA2oxs further suggest the pleiotropic role of GA2oxs in controlling growth and architecture in plants such as rice. GA2ox5, GA2ox6 and GA2ox9 were three genes encoding class C20 GA2oxs in rice. Mutants or transgenic rice overexpressing class C20 GA2oxs exhibited a broad range of mutant phenotypes, including semi-dwarfism, increased root system and higher tiller numbers that may favor grain yield. Mutations in the conserved domain III were found to affect the physiological activity of class C20 GA2oxs. Methods are described for controlling plant growth and architecture by controlling gene expression of gibberellin 2-oxidase in the plant.
