The present invention provides polynucleotides and related polypeptides of the ZmARGOS gene family. The invention provides genomic sequence for the ZmARGOS genes. ZmARGOS is responsible for controlling plant growth, organ size and yield in crop plants.

Compositions and methods comprising polynucleotides and polypeptides having 4-hydroxyphenylpyruvate dioxygenase (HPPD) activity and having insensitivity to an HPPD inhibitor are provided. Further provided are nucleic acid constructs, plants, plant cells, explants, seeds and grain having the HPPD sequences. Various methods of employing the HPPD sequences are provided. Such methods include, for example, methods for producing an HPPD inhibitor tolerant plant, plant cell, explant or seed and methods of controlling weeds in a field containing a crop employing the plants and/or seeds disclosed herein. Methods are also provided to identify additional HPPD variants. Further provided are various methods and compositions that allow the various HPPD polypeptides and variant and fragments thereof to be expressed in a chloroplast or transported to a chloroplast.

Methods of making a targeted modification in a male fertility gene in the genome of a plant are disclosed. The methods involve contacting a plant cell with an engineered double-strand-break-inducing agent capable of inducing a double-strand break in a target sequence in the male fertility gene and identifying a cell comprising an alteration in the target sequence. Also disclosed are plants, plant cells, plant parts, and seeds comprising a male fertility gene with an alteration in a male fertility gene. Nucleic acid molecules comprising male fertility genes with at least one targeted modification therein, optimized nucleic acid molecules encoding endonucleases that are engineered double-strand-break-inducing agents and expression cassettes, host cells, and plants comprising one or more of the nucleic acid molecules are further disclosed.

The invention relates to methods and compositions for identifying soybean plants that are tolerant, have improved tolerance or are susceptible to Charcoal Rot Drought Complex. The methods use molecular genetic markers to identify, select and/or construct tolerant plants or identify and counter-select susceptible plants. Soybean plants that display tolerance or improved tolerance to Charcoal Rot Drought Complex that are generated by the methods of the invention are also a feature of the invention. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

Transgenic oilseeds having increased total fatty acid content of at least 10% and altered fatty acid profiles when compared to the total fatty acid content of null segregant oilseeds are described. Novel DGAT genes are used to achieve the increase in seed storage lipids.

Compositions and methods useful in identifying and/or selecting maize plants that have anthracnose stalk rot resistance are provided herein. The resistance may be newly conferred or enhanced relative to a control plant. The methods use maize markers on chromosome 10 to identify, select and/or construct resistant plants. Maize plants generated by the methods also provided.

Increased availability of high throughput genotyping technology together with advances in DNA sequencing and in the development of statistical methodology appropriate for genome-wide association scan mapping in presence of considerable population structure contributed to the increased interest association mapping in plants. While most published studies in crop species are candidate gene-based, genome-wide studies are on the increase. New types of populations providing for increased resolution and power of detection of modest-size effects and for the analysis of epistatic interactions have been developed. Classical biparental mapping remains the method of choice for mapping the effects of alleles rare in germplasm collections, such as some disease resistance genes or alleles introgressed from exotic germplasm. © 2010 Elsevier Ltd.

A seed handling tool includes a handle connected to a working body. The working body includes a working surface, which further includes a plurality of seed retention points. A seed retention source is provided to allow the seed handling tool to pick up and retain seeds at the seed retention points. In some embodiments, the seeds may also be released from the seed retention points. A method for retaining a plurality of seeds by the seed handling tool includes moving the seed handling tool to a position where the working surface is adjacent to a plurality of seeds, and picking up and retaining seeds at a plurality of seed retention points fixed at the working surface. In some embodiments, the method may also include releasing the plurality of seeds from the seed retention points.

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 isolated insecticidal proteins and nucleic acids. The sequences find use in the construction of expression vectors for subsequent transformation into organisms of interest, as probes for the isolation of other homologous (or partially homologous) genes. The insecticidal proteins find use in controlling or killing lepidopteran, coleopteran, dipteran, fungal, hemipteran, and nematode pest populations and for producing compositions with insecticidal activity.
