The invention relates to high-protein-content soybeans and methods of producing high-protein-content soybeans. The methods can relate to proteome rebalancing and regulating the abscisic acid (ABA) pathway. The methods can relate to modulating transcription factors such as AiP2. AiP2 modification can increase soybean protein content and indicates the strategic path to alter seed protein is contained within the mechanisms of abscisic acid control of seed development.

The present invention provides for transgenic plants and methods of producing such transgenic plants, wherein the transgenic plants express an increased amounts of PYL9 to interact with abscisic acid (ABA) thereby activating enhanced drought resistance and leaf senescence relative to control or wild-type plants.

This disclosure provides methods of downregulating or eliminating gene expression of one or more Dynamic Influencer of Gene expression (DIG) and/or one or more DIG-like (DIL) sequences in plants and plant cells, as well as constructs and compositions useful in such methods. Such recombinant plants can have decreased abscisic acid (ABA) sensitivity, decreased salt sensitivity, or both.

Described herein are recombinant polynucleotides and vectors that can encode and/or express WRKY transcription factor polypeptides. Also described herein are recombinant WRKY transcription factor polypeptides. Also described herein are transgenic plant cells and plants that can overexpress a WRKY transcription factor polypeptide and methods of increasing tolerance to abiotic and/or biotic stressors in plants.

Provided are a method for improving rice yield by jointly knocking out ABA receptor PYL family genes and a use thereof.

Hypersensitive PYR/PYL receptor polypeptides comprising an amino acid substitution in a type 2 protein phosphatase (PP2C) binding interface are provided. Compositions and plants comprising the hypersensitive PYR/PYL receptor polypeptides and methods of producing plants comprising a hypersensitive PYR/PYL receptor polypeptide are also provided.

The invention relates to high-protein-content soybeans and methods of producing high-protein-content soybeans. The methods can relate to proteome rebalancing and regulating the abscisic acid (ABA) pathway. The methods can relate to modulating transcription factors such as AiP2. AiP2 modification can increase soybean protein content and indicates the strategic path to alter seed protein is contained within the mechanisms of abscisic acid control of seed development.

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.

The present invention provides for transgenic plants and methods of producing such transgenic plants, wherein the transgenic plants express an increased amounts of PYL9 to interact with abscisic acid (ABA) thereby activating enhanced drought resistance and leaf senescence relative to control or wild-type plants.

Hypersensitive PYR/PYL polypeptides, compositions, and methods are provided.
