The invention relates to novel maize plants, seeds and compositions, as well as improvements to maize plant breeding and methods for creating modifications in maize plant genomes.

Modified PYR/PYL receptors activated by orthogonal ligands are provided.

The invention relates to plant transcription factor polypeptides, polynucleotides that encode them, homologs from a variety of plant species, and methods of using the polynucleotides and polypeptides to produce transgenic plants having advantageous properties compared to a reference plant. Sequence information related to these polynucleotides and polypeptides can also be used in bioinformatic search methods and is also disclosed.

The present disclosure provides methods for regulating stomata in plants, improving drought tolerance, and increasing resistance to bacterial pathogens through overexpression of genes NHR1 or GCN4. Also provided are transgenic plants with improved drought tolerance and increased resistance to bacterial pathogens produced by such methods.

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.

Protein dimers that are modified to detect plant hormones are provided. In some embodiments, a protein dimer is provided comprising a first amino acid sequence and a second amino acid sequence, wherein the protein dimer dissociates in the presence of a plant hormone and the dissociation results in a detectable signal.

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