Abstract: The present invention relates to a method of separating amino acids from an aqueous solution comprising amino acids as well as proteins and/or protein decomposition products by combining phosphoric acid with the aqueous solution to precipitate an amino acid monophosphate. The precipitate so formed may be separated from the aqueous solution and used as such, e.g. in plant fertilizer compositions. The precipitate may be redissolved in a suitable liquid, after which phosphate and amino acid may be separated following conventional methods. In either case, the present invention enables highly selective precipitation of arginine and/or lysine monophosphate as crystals.

Abstract: The present invention relates to a fertilizer comprising at least one basic L-amino acid, such as arginine or lysine, wherein a substantial portion of the basic L-amino acid content is present as its monophosphate. The basic L-amino acid phosphate may be combined with a binder and/or provided with an outermost layer acting as a coating. The invention also relates to a method of enhancing the growth of a plant by making a basic L-amino acid phosphate available to the plant.

Abstract: A composition, such as a liquid seed coating composition, comprises at least one macro nutrient and at least one microbe, which macro nutrient includes nitrogen in the form of a basic L-amino acid in association with phosphorus. The composition allows for an enhanced environment for planted seeds, e.g. by providing nitrogen in a form which is available for extended periods of time. Further, as compared to prior art products, the nitrogen is provided in a form which has been shown to be more beneficial to microbes present in soil surrounding the plant in terms of toxicity. The composition is advantageously a liquid slow release seed coating composition. Further, the invention includes a seed treated to extend the duration of the nitrogen effect without lethal effects to surrounding microbes, and a method of treating a seed to achieve the same objective.

Abstract: The present invention relates to the promotion of the growth of at least one plant by providing a fertilizer composition-comprising at least one zeolite, into the pores of which at least one basic L-amino acid has been adsorbed; adding the fertilizer composition to a medium for plant growth; and culturing a plant therein. The invention will provide the release of nitrogen from the fertilizer composition during culture of the plant at a rate which is advantageously used by the plant. The invention also relates to a fertilizer composition as such, optionally combined with a medium for plant growth to make up a growth-promoting material. The invention is advantageously used to reduce the resources required in the fertilization of slowly growing plants, where repeated supply of nutrients as well as leakage of nitrogen amounts to large costs to society.

Abstract: Transcription factor polynucleotides and polypeptides incorporated into nucleic acid constructs, including expression vectors, have been introduced into plants and were ectopically expressed. Transgenic plants transformed with many of these constructs have been shown to have increased tolerance to an abiotic stress (in some cases, to more than one abiotic stress), increased growth, and/or increased biomass. The abiotic stress may include, for example, salt, hyperosmotic stress, water deficit, heat, cold, drought, and/or low nutrient conditions.

Abstract: This invention relates to fertilizer and herbicide compositions. The present invention provides a composition for selective fertilization of a transgenic plant comprising a polypeptide which metabolizes a D-amino acid substrate; said composition comprising said D-amino acid substrate. Another aspect of the present invention provides a selective herbicide composition comprising a D-amino acid. Such a herbicide will inhibit or reduce the growth of plants which do not contain the appropriate D-amino acid metabolizing enzyme, while the growth of transgenic plants which are able to metabolize the D-amino acid will be unaffected or, more preferably, be increased or enhanced. Methods and means are also provided for selectively modulating the growth and stress tolerance such plants using D-amino acids.
