The present disclosure provides methods for increasing meiotic recombination in crop plants, as well as plants and seeds produced by such methods.

The invention provides corn event MON 87411, and plants, plant cells, seeds, plant parts, and commodity products comprising event MON 87411. The invention also provides polynucleotides specific for event MON 87411 and plants, plant cells, seeds, plant parts, and commodity products comprising polynucleotides specific for event MON 87411. The invention also provides methods related to event MON 87411.

Compositions and methods for controlling pests are provided. The methods involve transforming organisms with a nucleic acid sequence encoding an insecticidal protein. In particular, the nucleic acid sequences are useful for preparing plants and microorganisms that possess insecticidal activity. Thus, transformed bacteria, plants, plant cells, plant tissues and seeds are provided. Compositions are insecticidal nucleic acids and proteins of bacterial species. The sequences find use in the construction of expression vectors for subsequent transformation into organisms of interest including plants, as probes for the isolation of other homologous (or partially homologous) genes. The pesticidal proteins find use in controlling, inhibiting growth or killing Hemipteran, Lepidopteran, Coleopteran, Dipteran, fungal, and nematode pest populations and for producing compositions with insecticidal activity.

Provided herein is a method for improving growth, stress tolerance and productivity of a plant. Also provided herein is a method for increasing seed quality of a plant. Specifically, the disclosure provides a method for improving growth, stress tolerance and productivity of a plant, comprising: providing a transgenic plant, which includes a reduced expression on an MYBS2 gene as relative to its wild-type counterpart; and a method for increasing seed quality of a plant, comprising: providing a seed from a transgenic plant, which overexpresses a full-length MYBS2 gene or a mutant MYBS2 gene as relative to its wild-type counterpart.

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.

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.

A Yr4DS gene of Aegilops tauschii and its use thereof in stripe rust resistance breeding of Triticeae plants. Said gene has a sequence as shown in SEQ ID NO. 1, SEQ ID NO. 3, SEQ ID NO. 5, SEQ ID NO. 7, SEQ ID NO. 9, or SEQ ID NO. 10.

A method according to an embodiment of the present disclosure is for enhancing disease resistance of a plant against Soybean mosaic virus compared to a non-transformant. The method may include transforming a plant cell of the plant with a recombinant vector containing a gene encoding Glycine max purple acid phosphatase 2.1 (GmPAP2.1) protein from Glycine max to overexpress the gene encoding GmPAP2.1 protein. As the GmPAP2.1 gene from Glycine max of the present invention can modulate disease resistance against Soybean mosaic virus, it is expected to be applied for development of new cultivars with enhanced resistance to Soybean mosaic virus to thereby increase soybean productivity.
