Methods and systems for producing a protein of interest within a plant or a portion of a plant are provided herein. The method includes introducing one or more nucleic acid into the plant or the portion of the plant, the nucleic acid including a nucleotide sequence encoding the protein of interest and incubating the plant or the portion of the plant under conditions that permit the expression of the nucleotide sequence encoding the protein of interest. The method also includes adding a medium amendment including a calcium carbonate source, such as aragonite, to a medium environment of the plant.

Transgenic seed for crops with enhanced agronomic traits are provided by trait-improving recombinant DNA in the nucleus of cells of the seed where plants grown from such transgenic seed exhibit one or more enhanced traits as compared to a control plant. Of particular interest are transgenic plants that have increased yield. The present invention also provides recombinant DNA molecules for expression of a protein, and recombinant DNA molecules for suppression of a protein.

Disclosed herein are genetically modified plants expressing multiple animal milk proteins. Further disclosed are vectors for expressing in a plant and parts thereof, multiple mammalian milk proteins; genetically modified and or gene-edited plants having at least one cell expressing and producing at least two recombinant mammalian milk proteins wherein expression may be in a seed, bean, grain, fruit, nut, legume, leaf, stem, root, or portion thereof, the recombinant protein being produced by the plant cell; and a method of producing a food, medicament, cosmetic or blocking composition from the genetically modified or gene-edited plant. Reduction or elimination of seed storage proteins in a cell or cells wherein the milk proteins are expressed, or reduction of plant enzymes that can increase the content of oleic and/or stearic fatty acids and/or reduce the content of saturated fats in the plants or plant products are also disclosed.

This invention provides recombinant DNA constructs, transgenic plant nuclei and cells with such recombinant DNA construct for expression of proteins that are useful for imparting enhanced agronomic trait(s) to transgenic crop plants. This invention also provides transgenic plants and progeny seed comprising the transgenic plant cells where the plants are selected for having an enhanced trait selected from the group of traits consisting of enhanced water use efficiency, enhanced cold tolerance, increased yield, enhanced nitrogen use efficiency, enhanced seed protein and enhanced seed oil. Also disclosed are methods for manufacturing transgenic seed and plants with enhanced traits.

Provided are compositions comprising polynucleotides encoding modified diacylglycerol acyltransferase-1 (DGAT1) polypeptides having improved properties, such as increased enzymatic activity and/or increased stability. Plants, plant cells, seed, grain and comprising the polynucleotides are provided which have one or more of increased fatty acid or protein content. Methods of generating the polynucleotides in plant cells include transformation and genetic modification. Methods of employing the polynucleotides in plants, methods for increasing DGAT1 activity in a plant, and methods for increasing fatty acid content or protein content in a plant are provided.

The invention relates to methods for increasing seed yield, increasing the total content of protein and/or lipid in seeds and reducing glucosinolate levels by reducing the expression or activity of UPL3. The invention also relates to genetically altered plants characterised by the above phenotypes and methods of producing such plants.

Provided herein are compositions and methods for producing milk proteins in plants, which allow for safe, sustainable and humane production of milk proteins for commercial use, such as use in food compositions. The disclosure provides recombinant fusion proteins comprising a milk protein, or fragment thereof and a structured mammalian, avian, plant, or fungal protein, or fragment thereof. The disclosure also provides methods for producing the recombinant fusions proteins, and food compositions comprising the same.

The present invention is directed to a transgenic soybean plant having increased seed protein content and/or increased seed oil content comprising a polynucleotide encoding a β-ConGlycinin soybean seed storage promoter that functions in the soybean plant operably linked to a polynucleotide encoding a soybean seed storage polypeptide having β-ConGlycinin activity. The invention is further directed to a method of increasing seed protein content and/or increasing seed oil content of a soybean plant comprising transforming the soybean plant with a polynucleotide encoding a β-ConGlycinin soybean seed storage promoter that functions in the soybean plant operably linked to a polynucleotide encoding a soybean seed storage polypeptide having β-ConGlycinin activity.

Method of increasing protein content in a eukaryotic cell comprising an NF-YC4 gene comprising modifying the transcriptional repressor binding site; method of producing a plant with increased protein content comprising crossing and selecting for increased protein content; method of increasing resistance to a pathogen or a pest in a plant cell or plant comprising an NF-YC4 gene comprising modifying the transcriptional repressor binding site, alone or in further combination with expressing QQS in the plant cell or plant; method for producing a plant with increased resistance to a pathogen or a pest comprising crossing and selecting for increased resistance to the pathogen or the pest; a cell, collection of cells, tissue, organ, or organism, such as a plant, in which the NF-YC4 gene comprises a promoter comprising a transcriptional repressor binding site that has been modified so that the transcriptional repressor cannot prevent transcription of the NF-YC4; plants and hybrids thereof; and seeds.
