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.

Disclosed herein are methods for identifying amino acid residues of NLRs that are likely involved in pathogen immunity. Also disclosed are methods for modifying plant immunity which comprise modifying (e.g., substituting, deleting, or adding an amino acid before or after) one or more of the amino acid residues that have been identified as being likely involved in pathogen immunity.

This technology relates in part to methods of identifying plant cultivars based on the terpene synthase genes that are identified and/or quantified (e.g., copy number, ploidy) in the cultivars. The methods provided herein permit plant cultivars with desired characteristics/phenotypes, e.g., a desired terpene production profile, to be selected for use in various applications, such as agriculture (e.g., selecting cultivars for breeding desired characteristics and/or lineages) and medicine (e.g., therapeutic activity).

Provided are compositions and methods for altering TFL1 levels in soybean plants. Methods and compositions are also provided for altering the expression of genes related to the timing of terminal differentiation of stem tips through suppression, mutagenesis and/or editing of the TFL1 gene. Modified plant cells and plants having a suppression element or mutation reducing the expression or activity of a TFL1 gene are further provided comprising reduced TFL1 levels and improved characteristics, such as reduced plant height and increased lodging resistance.

Improved methods and means are provided to modify in a targeted manner the genome of a plant cell or plant at a predefined site via bacterial transformation.

This invention relates to a plant E3 ubiquitin ligase (termed DA2) which acts synergistically with DA1 to control seed and organ size. Methods of increasing plant yield are provided that comprise reducing the expression or activity of DA2 in a plant that is deficient in DA1 expression or activity. Plants with increased yield and methods of producing such plants are also 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.

A CC-NBS-LRR gene NLR1-V encoded by the enduring and broad-spectrum gene Pm21 which is resistant to powdery mildew in the wheat-Haynaldia villosa 6VS/6AL translocation line in Nannong 9918, and an expression vector and use thereof. The ORF sequence of the NLR1-V gene having an NLR domain is as shown in SEQ ID NO: 1, and the encoded amino acid sequence is as shown in SEQ ID NO: 2.

The present invention relates to a transgenic plant which integrated into its genome an exogenous polynucleotide encoding a polypeptide which confers resistance to one or more races of Puccinia graminis f. sp. tritici, such as the Ug99 group of races Puccinia graminis f. sp. tritici.

Provided are isolated polypeptides, isolated polynucleotides encoding same, nucleic acid constructs comprising same, transgenic cells expressing same, transgenic plants expressing same and method of using same for increasing yield, abiotic stress tolerance, growth rate, biomass, vigor, oil content, photosynthetic capacity, seed yield, fiber yield, fiber quality, fiber length, early flowering, grain filling period, harvest index, plant height, and/or nitrogen use efficiency of a plant.
